Allow to store and track symlink in the repository. A symlink is stored
the same way as a regular file, only with the appropriate mode bits set.
The symlink target is therefore stored in a blob object.
This will hopefully make our udev repository fully functional. :)

As suggested by Nicolas Pitre

Not everybody has "d_type".

The show-files long options are cumbersome to type.  This patch adds
equivalent short options.

Also add missing "unmerged" to usage string.

Finally reduce the number of lines for argument parsing in half.

This can be used with the famous dontdiff file as follows to find out
about uncommitted files just like dontdiff is used with the diff
command:

    show-files --others --exclude-from=dontdiff

and the exclude list can be reversed with the --ignore switch.

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

We use that to specify alternative index files, which can be useful
if you want to (for example) generate a temporary index file to do
some specific operation that you don't want to mess with your main
one with.

It defaults to the regular ".git/index" if it hasn't been specified.

The flag also implies "--stage", since unmerged file information doesn't
make sense without the full output.

This adds --stage option to show-files command.  It shows
file-mode, SHA1, stage and pathname.  Record separator follows
the usual convention of -z option as before.

This adds NUL-terminated output (-z) to show-files.  This is necessary
for merge-trees script to deal with filenames with embedded newlines.
