Re: realloc

I could be wrong, but shouldn't

be changed to call xrealloc?  That, or assign to a different variable and check
for NULL.

This should affect the last four hits below.

/scratch/welinder/git> grep -w realloc *.c
daemon.c:               newlist = realloc(socklist, sizeof(int) *
(socknum + 1));
diff-delta.c:                           out = realloc(out, outsize);
git.c:          cmdname = realloc(cmdname, cmdname_alloc * sizeof(*cmdname));
ls-files.c:             which->excludes = realloc(which->excludes,
sha1_file.c:                            buf = realloc(buf, size);

There is no excuse for not using xrealloc() in git.c,
ls-files.c, and sha1_file.c.

The diff-delta.c code wants to be independent from the rest of
git code, so it probably should check the returned value itself.

Historically to a certain degree daemon.c also wanted to be
independent from the rest of git, but I suspect it still is the
case (it uses small pieces from packet interface but that is
about it).
