Kay Sievers noticed that you can have both path and path/file in
the cache and write-tree happily creates a tree object from such
a state. Since a merge can result in such situation and the
user should be able to see the situation by looking at the
cache, rather than forbidding add_cache_entry() to create such
conflicts, fix it by making write-tree refuse to write such an
nonsensical tree. Here is a test case.

$ ls -a
./ ../
$ git-init-db

Introduce xmalloc and xrealloc to die gracefully with a descriptive
message when out of memory, rather than taking a SIGSEGV.

Of course, we can't even generate such an index yet, but give me
some time. This is a cunning plan. Let's see if it actually works.
(I feel like Wile E Coyote, waiting for the big rock to fall).
This allows using a git tree over NFS with different byte order, and
makes it possible to just copy a fully populated repository and have
the end result immediately usable (needing just a refresh to update
the stat information).
Now there is error() for "library" errors and die() for fatal "application"
errors. usage() is now used strictly only for usage errors.

It now requires the "--add" flag before you add any new files, and
a "--remove" file if you want to mark files for removal. And giving
it the "--refresh" flag makes it just update all the files that it
already knows about.
It's got some debugging printouts etc still in it, but testing on the
kernel seems to show that it does indeed fix the issue with huge tree
files for each commit.
The tool interface sucks (especially "committing" information, which is just
me doing everything by hand from the command line), but I think this is in
theory actually a viable way of describing the world. So copyright it.
