Fix pack-index issue on 64-bit platforms a bit more portably.
Apparently <stdint.h> is not enough for uint32_t on OpenBSD; use
"unsigned int" -- hopefully that would stay 32-bit on every
platform we care about, at least until we update the pack-index
file format.
Our sha1 routines optimized for architectures use uint32_t and
expects '#include <stdint.h>' to be enough, so OpenBSD on arm or
ppc might have similar issues down the road, I dunno.
The previous commit makes -u to mean "I do want to remove the
local changes, just update it from the read tree" only for
one-way merge. It makes sense to have it depend on the
"--reset" flag instead.

send-email: quiet some warnings, reject invalid addresses
I'm not sure why we never actually rejected invalid addresses in
the first place. We just seemed to be using our email validity
checkers to kill duplicates.
Now we just drop invalid email addresses completely and warn
the user about it.
Since we support local sendmail, we'll also accept username-only
addresses.

send-email: allow sendmail binary to be used instead of SMTP
This should make local mailing possible for machines without
a connection to an SMTP server.
It'll default to using /usr/sbin/sendmail or /usr/lib/sendmail
if no SMTP server is specified (the default). If it can't find
either of those paths, it'll fall back to connecting to an SMTP
server on localhost.

read-tree -u one-way merge fix to check out locally modified paths.
The "-u" flag means "update the working tree files", but to
other types of merges, it also implies "I want to keep my local
changes" -- because they prevent local changes from getting lost
by using verify_uptodate. The one-way merge is different from
other merges in that its purpose is opposite of doing something
else while keeping unrelated local changes. The point of
one-way merge is to nuke local changes. So while it feels
somewhat wrong that this actively loses local changes, it is the
right thing to do.
builtin-grep: use external grep when we can take advantage of it
It's not perfect, but it gets the "git grep some-random-string" down to
the good old half-a-second range for the kernel.
It should convert more of the argument flags for "grep", that should be
trivial to expand (I did a few just as an example). It should also bother
to try to return the right "hit" value (which it doesn't, right now - the
code is kind of there, but I didn't actually bother to do it _right_).
Also, right now it _just_ limits by number of arguments, but it should
also strictly speaking limit by total argument size (ie add up the length
of the filenames, and do the "exec_grep()" flush call if it's bigger than
some random value like 32kB).
But I think that it's _conceptually_ doing all the right things, and it
seems to work. So maybe somebody else can do some of the final polish.

When renaming leading/a/filename to leading/b/filename (and
"filename" is sufficiently long), we tried to squash the rename
to "leading/{a => b}/filename". However, when "/a" or "/b" part
is empty, we underflowed and tried to print a substring of
length -1.
Now that the one-way merge strategy does the right thing wrt files that do
not exist in the result, just remove all the random crud we did in "git
reset" to do this all by hand.
Instead, just pass in "-u" to git-read-tree when we do a hard reset, and
depend on git-read-tree to update the working tree appropriately.
This basically means that git reset turns into
# Always update the HEAD ref
git update-ref HEAD "$rev"
case "--soft"
# do nothing to index/working tree
case "--hard"
# read index _and_ update working tree
git-read-tree --reset -u "$rev"
case "--mixed"
# update just index, report on working tree differences
git-read-tree --reset "$rev"
git-update-index --refresh
which is what it was always semantically doing, it just did it in a
rather strange way because it was written to not expect git-read-tree to
do anything to the working tree.

git diff: support "-U" and "--unified" options properly
We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS
environment variable, but strangely enough we would _not_ parse them as
part of the normal diff command line (where we only accepted "-u").
This adds parsing of -U and --unified, both with an optional numeric
argument. So now you can just say
git diff --unified=5
to get a unified diff with a five-line context, instead of having to do
something silly like
GIT_DIFF_OPTS="--unified=5" git diff -u
(that silly format does continue to still work, of course).

* lt/fix-config:
git config syntax updates
Another config file parsing fix.
checkout: use --aggressive when running a 3-way merge (-m).
Fix git-pack-objects for 64-bit platforms
with manual adjustment of t/t1300 for "git repo-config --list" option.
This updates the hierarchical section name syntax to
[section<space>+"<randomstring>"]
where the only rule for "randomstring" is that it can't contain a newline,
and if you really want to insert a double-quote, you do it with \".
It turns that into the section name "secion.randomstring". The
"section" part is still case insensitive, but the "randomstring"
part is case sensitive.
So you could use this for things like
[email "torvalds@osdl.org"]
name = Linus Torvalds
if you wanted to do the "email->name" conversion as part of the config
file format (I'm not claiming that is sensible, I'm just giving it as an
insane example). That would show up as the association
email.torvalds@osdl.org.name -> Linus Torvalds
which is easy to parse (the "." in the email _looks_ ambiguous, but it
isn't: you know that there will always be a single key-name, so you find
the key name with "strrchr(name, '.')" and things are entirely
unambiguous).
Repo-config is updated to be able to parse the new format, and also
write things out in the new format.
[jc: rolled two patches from Linus and one fix-up from Sean into one,
with additional adjustments for t/t1300 test to check the case
insensitiveness of section base and variable and case sensitiveness
of the extended section part. Then stripped some part off to make
the result applicable to the stale 1.3.X series that does not have
recent enhancements. ]

If the variable we need to store should go into a section
that currently only has a single variable (not matching
the one we're trying to insert), we will already be into
the next section before we notice we've bypassed the correct
location to insert the variable.
To handle this case we store the current location as soon
as we find a variable matching the section of our new
variable.
This breakage was brought up by Linus.

checkout: use --aggressive when running a 3-way merge (-m).
After doing an in-index 3-way merge, we always do the stock
"merge-index merge-one-file" without doing anything fancy;
use of --aggressive helps performance quite a bit.
The offset of an object in the pack is recorded as a 4-byte integer
in the index file. When reading the offset from the mmap'ed index
in prepare_pack_revindex(), the address is dereferenced as a long*.
This works fine as long as the long type is four bytes wide. On
NetBSD/sparc64, however, a long is 8 bytes wide and so dereferencing
the offset produces garbage.

apply: fix infinite loop with multiple patches with --index
When multiple patches are passed to git-apply, it will attempt
to open multiple file descriptors to an index, which means
multiple entries will be in the circular cache_file_list.

When we cut off the front of a filename to make it fit on the line, we add
a "..." in front. However, the way the "git diff" code was written, we
will never reset the prefix back to the empty string, so every single
filename afterwards will have the "..." prefix, whether appropriate or
not.
You can see this with "git diff v2.6.16.." on the current kernel tree,
since there are filenames with long names that changed there:
notice how the two Documentation/firmware** filenames caused the "..." to
be added, but then the later filenames don't want it, and it also screws
up the alignment of the line numbering afterwards.
Trivially fixed by moving the declaration (and initial setting) of the
"prefix" variable into the for-loop where it is used.

* Fixed Directory method, I _believe_ it's now correct in both cmdline and Eclipse.
* Directory method Now looks for localdir of "." and compares the repo dir, uses THIS as a basis for all directory level calculations.
* Added extra parameter to filenamesplit() to force stripping of "prepended" directory name. This ensures commits/updates etc work from any directory in the source tree.
* Modified argsfromdir() so it is "always" called. This means that when the client specifies a directory, the method can detect this and behave accordingly (this is currently only implemented for the '.' directory)
* Fixed "commit" method to correctly work from in a subdir
Fix users of prefix_path() to free() only when necessary
Unfortunately, prefix_path() sometimes returns a newly xmalloc()ed buffer,
and in other cases it returns a substring!
For example, when calling
git update-index ./hello.txt
prefix_path() returns "hello.txt", but does not allocate a new buffer. The
original code only checked if the result of prefix_path() was different from
what was passed in, and thusly trigger a segmentation fault.

This updates the user interface and generated diff data format.
* "diff --binary" is used to signal that we want an e-mailable
binary patch. It implies --full-index and -p.
* "apply --allow-binary-replacement" acquired a short synonym
"apply --binary".
* After the "GIT binary patch\n" header line there is a token
to record which binary patch mechanism was used, so that we
can extend it later. Currently there are two mechanisms
defined: "literal" and "delta". The former records the
deflated postimage and the latter records the deflated delta
from the preimage to postimage.
For purely implementation convenience, I added the deflated
length after these "literal/delta" tokens (otherwise the
decoding side needs to guess and reallocate the buffer while
inflating). Improvement patches are very welcomed.
This adds "binary patch" to the diff output and teaches apply
what to do with them.
On the diff generation side, traditionally, we said "Binary
files differ\n" without giving anything other than the preimage
and postimage object name on the index line. This was good
enough for applying a patch generated from your own repository
(very useful while rebasing), because the postimage would be
available in such a case. However, this was not useful when the
recipient of such a patch via e-mail were to apply it, even if
the preimage was available.
This patch allows the diff to generate "binary" patch when
operating under --full-index option. The binary patch follows
the usual extended git diff headers, and looks like this:
Each line is prefixed with a "length-byte", whose value is upper
or lowercase alphabet that encodes number of bytes that the data
on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ...,
'Z' means 26, 'a' means 27, ...). <data> is 1 or more groups of
5-byte sequence, each of which encodes up to 4 bytes in base85
encoding. Because 52 / 4 * 5 = 65 and we have the length byte,
an output line is capped to 66 characters. The payload is the
same diff-delta as we use in the packfiles.
On the consumption side, git-apply now can decode and apply the
binary patch when --allow-binary-replacement is given, the diff
was generated with --full-index, and the receiving repository
has the preimage blob, which is the same condition as it always
required when accepting an "Binary files differ\n" patch.
