traverse_trees_recursive(): propagate merge errors up
There were few places where merge errors detected deeper in the call chain
were ignored and not propagated up the callchain to the caller.
Most notably, this caused switching branches with "git checkout" to ignore
a path modified in a work tree are different between the HEAD version and
the commit being switched to, which it internally notices but ignores it,
resulting in an incorrect two-way merge and loss of the change in the work
tree.
unpack_trees(): minor memory leak fix in unused destination index
This adds a "discard_index(&o->result)" to the failure path, to reclaim
memory from an in-core index we built but ended up not using.
The *big* memory leak comes from the fact that we leak the cache_entry
things left and right. That's a very traditional and deliberate leak:
because we used to build up the cache entries by just mapping them
directly in from the index file (and we emulate that in modern times
by allocating them from one big array), we can't actually free them
one-by-one.
So doing the "discard_index()" will free the hash tables etc, which is
good, and it will free the "istate->alloc" but that is never set on the
result because we don't get the result from the index read. So we don't
actually free the individual cache entries themselves that got created
from the trees.
That's not something new, btw. We never did. But some day we should just
add a flag to the cache_entry() that it's a "free one by one" kind, and
then we could/should do it. In the meantime, this one-liner will fix
*some* of the memory leaks, but not that old traditional one.

Make 'unpack_trees()' have a separate source and destination index
We will always unpack into our own internal index, but we will take the
source from wherever specified, and we will optionally write the result
to a specified index (optionally, because not everybody even _wants_ any
result: the index diffing really wants to just walk the tree and index
in parallel).
This ends up removing a fair number more lines than it adds, for the
simple reason that we can now skip all the crud that tried to be
oh-so-careful about maintaining our position in the index as we were
traversing and modifying it. Since we don't actually modify the source
index any more, we can just update the 'o->pos' pointer without worrying
about whether an index entry got removed or replaced or added to.

Move 'unpack_trees()' over to 'traverse_trees()' interface
This not only deletes more code than it adds, it gets rid of a

replaces it with a set of smaller and simpler functions that use the

Make 'traverse_trees()' traverse conflicting DF entries in parallel
This makes the traverse_trees() entry comparator routine use the more
relaxed form of name comparison that considers files and directories
with the same name identical.
We pass in a separate mask for just the directory entries, so that the
callback routine can decide (if it wants to) to only handle one or the
other type, but generally most (all?) users are expected to really want
to see the case of a name 'foo' showing up in one tree as a file and in
another as a directory at the same time.
In particular, moving 'unpack_trees()' over to use this tree traversal
mechanism requires this.

Make 'traverse_tree()' use linked structure rather than 'const char *base'
This makes the calling convention a bit less obvious, but a lot more
flexible. Instead of allocating and extending a new 'base' string, we
just link the top-most name into a linked list of the 'info' structure
when traversing a subdirectory, and we can generate the basename by
following the list.
Perhaps even more importantly, the linked list of info structures also
gives us a place to naturally save off other information than just the
directory name.

This new helper is identical to base_name_compare(), except it compares
conflicting directory/file entries as equal in order to help handling DF
conflicts (thus the name).
Note that while a directory name compares as equal to a regular file
with the new helper, they then individually compare _differently_ to a
filename that has a dot after the basename (because '\0' < '.' < '/').
So a directory called "foo/" will compare equal to a file "foo", even
though "foo.c" will compare after "foo" and before "foo/"
This will be used by routines that want to traverse the git namespace
but then handle conflicting entries together when possible.

When the rewriteRoot setting is used with git-svn, it causes the svn
IDs added to commit messages to bear a different URL than is actually
used to retrieve Subversion data.
It is common for Subversion repositories to be available multiple
ways: for instance, HTTP to the public, and svn+ssh to people with
commit access. The need to switch URLs for access is fairly common as
well -- perhaps someone was just given commit access. To switch URLs
without having to rewrite history, one can use the old url as a
rewriteRoot, and use the new one in the svn-remote url setting.
This works well for svn fetching and general git commands.
However, git-svn dcommit, rebase, and perhaps other commands do not
work in this scenario. They scan the svn ID lines in commit messages
and attempt to match them up with url lines in [svn-remote] sections
in the git config.
This patch allows them to match rewriteRoot options, if such options
are present.

get_pathspec(): die when an out-of-tree path is given
An earlier commit d089ebaa (setup: sanitize absolute and funny paths) made
get_pathspec() aware of absolute paths, but with a botched interface that
forced the callers to count the resulting pathspecs in order to detect
an error of giving a path that is outside the work tree.
This fixes it, by dying inside the function.
We had ls-tree test that relied on a misfeature in the original
implementation of its pathspec handling. Leading slashes were silently
removed from them. However we allow giving absolute pathnames (people
want to cut and paste from elsewhere) that are inside work tree these
days, so a pathspec that begin with slash _should_ be treated as a full
path. The test is adjusted to match the updated rule for get_pathspec().
Earlier I mistook three tests given by Robin that they should succeed, but
these are attempts to add path outside work tree, which should fail
loudly. These tests also have been fixed.

Teach git mergetool to use custom commands defined at config time
Currently git mergetool is restricted to a set of commands defined
in the script. You can subvert the mergetool.<tool>.path to force
git mergetool to use a different command, but if you have a command
whose invocation syntax does not match one of the current tools then
you would have to write a wrapper script for it.
This patch adds two git config variable patterns which allow a more
flexible choice of merge tool.
If you run git mergetool with -t/--tool or the merge.tool config
variable set to an unrecognized tool then git mergetool will query the
mergetool.<tool>.cmd config variable. If this variable exists, then git
mergetool will treat the specified tool as a custom command and will use
a shell eval to run the command with the documented shell variables set.
mergetool.<tool>.trustExitCode can be used to indicate that the exit
code of the custom command can be used to determine the success of the
merge.
