Handle core.symlinks=false case in merge-recursive.
If the file system does not support symbolic links (core.symlinks=false),
merge-recursive must write the merged symbolic link text into a regular
file.
While we are here, fix a tiny memory leak in the if-branch that writes
real symbolic links.

Add core.symlinks to mark filesystems that do not support symbolic links.
Some file systems that can host git repositories and their working copies
do not support symbolic links. But then if the repository contains a symbolic
link, it is impossible to check out the working copy.
This patch enables partial support of symbolic links so that it is possible
to check out a working copy on such a file system. A new flag
core.symlinks (which is true by default) can be set to false to indicate
that the filesystem does not support symbolic links. In this case, symbolic
links that exist in the trees are checked out as small plain files, and
checking in modifications of these files preserve the symlink property in
the database (as long as an entry exists in the index).
Of course, this does not magically make symbolic links work on such defective
file systems; hence, this solution does not help if the working copy relies
on that an entry is a real symbolic link.

show_date(): rename the "relative" parameter to "mode"
Now, show_date() can print three different kinds of dates: normal,
relative and short (%Y-%m-%s) dates.
To achieve this, the "int relative" was changed to "enum date_mode
mode", which has three states: DATE_NORMAL, DATE_RELATIVE and
DATE_SHORT.
Since existing users of show_date() only call it with relative_date
being either 0 or 1, and DATE_NORMAL and DATE_RELATIVE having these
values, no behaviour is changed.

that's an illogical thing to do, since "git show" is defined to be a
non-revision-walking action, which means the range operator be pointless
and wrong. The fact that we happily accept it (and then _only_ show
v1.5.0, which is the positive end of the range) is quite arguably not very
logical.
We should complain, and say that you can only do "no_walk" with positive
refs. Negative object refs really don't make any sense unless you walk
the obejct list (or you're "git diff" and know about ranges explicitly).

cvsserver: Make always-binary mode a config file option
The config option gitcvs.allbinary may be set to force all entries to
get the -kb flag.
In the future the gitattributes system will probably be a more
appropriate way of doing this, but that will easily slot in as the
entries lines sent to the CVS client now have their kopts set via the
function kopts_from_path().
In the interim it might be better to not just have a all-or-nothing
approach, but rather detect based on file extension (or file contents?).
That would slot in easily here as well. However, I personally prefer
everything to be binary-safe, so I just switch the switch.

cvsserver: Remove trailing "\n" from commithash in checkin function
The commithash for updating the ref is obtained from a call to
git-commit-tree. However, it was returned (and stored) with the
trailing newline. This meant that the later call to git-update-ref that
was trying to update to $commithash was including the newline in the
parameter - obviously that hash would never exist, and so git-update-ref
would always fail.
The solution is to chomp() the commithash as soon as it is returned by
git-commit-tree.

Make 'cvs ci' lockless in git-cvsserver by using git-update-ref
This makes "ci" codepath lockless by following the usual
"remember the tip, do your thing, then compare and swap at the
end" update pattern using update-ref. Incidentally, by updating
the code that reads where the tip of the head is to use
show-ref, it makes it safe to use in a repository whose refs are
pack-pruned.
I noticed that other parts of the program are not yet pack-refs
safe, but tried to keep the changes to the minimum.
This function is called only once in the whole source tree. Let's move
its code inline instead, which is also in the spirit of removing as much
object type char arrays as possible (not that this patch does anything for
that but at least it is now a local matter).

convert object type handling from a string to a number
We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value. One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.
This is an initial step for the removal of the version using a char array
found in object reading code paths. The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

First there are too many offsets there and it is getting confusing.
So 'offset' is now 'curpos' to distinguish from other offsets like
'obj_offset'.
Then structures like x = foo(x, &y) are now done as y = foo(&x).
It looks more natural that the result y be returned directly and
x be passed as reference to be updated in place. This has the effect
of reducing some line length and removing a few, needing a bit less
stack space, and it even reduces the compiled code size.

Let's have hdr be a simple char pointer/array when possible, and let's

The object type is already restricted to 10 bytes in parse_sha1_header()

32 bytes is plenty.

git-apply: do not fix whitespaces on context lines.
Internal function apply_line() is called to copy both context lines
and added lines to the output buffer, while possibly fixing the
whitespace breakages depending on --whitespace=strip settings.
However, it did its fix-up on both context lines and added lines.
This resulted in two symptoms:
(1) The number of lines reported to have been fixed up included
these context lines.
(2) However, the lines actually shown were limited to the added
lines that had whitespace breakages.
diff --cc: integer overflow given a 2GB-or-larger file
Few of us use git to compare or even version-control 2GB files,
but when we do, we'll want it to work.
Reading a recent patch, I noticed two lines like this:
int len = st.st_size;
Instead of "int", that should be "size_t". Otherwise, in the
non-symlink case, with 64-bit size_t, if the file's size is 2GB,
the following xmalloc will fail:
result = xmalloc(len + 1);
trying to allocate 2^64 - 2^31 + 1 bytes (assuming sign-extension
in the int-to-size_t promotion). And even if it didn't fail, the
subsequent "result[len] = 0;" would be equivalent to an unpleasant
"result[-2147483648] = 0;"
The other nearby "int"-declared size variable, sz, should also be of
type size_t, for the same reason. If sz ever wraps around and becomes
negative, xread will corrupt memory _before_ the "result" buffer.

was meaningless. This fixes it.

Allow arbitrary number of arguments to git-pack-objects
If a repository ever gets in a situation where there are too many
packs (more than 60 or so), perhaps because of frequent use of
git-fetch -k or incremental git-repack, then it becomes impossible to
fully repack the repository with git-repack -a. That command just
dies with the cryptic message
fatal: too many internal rev-list options
This message comes from git-pack-objects, which is passed one command
line option like --unpacked=pack-<SHA1>.pack for each pack file to be
repacked. However, the current code has a static limit of 64 command
line arguments and just aborts if more arguments are passed to it.
Fix this by dynamically allocating the array of command line
arguments, and doubling the size each time it overflows.
