read_line is now strbuf_getline, and is a first class citizen, it returns 0
when reading a line worked, EOF else.
The ->eof marker was used non-locally by fast-import.c, mimic the same
behaviour using a static int in "read_next_command", that now returns -1 on
EOF, and avoids to call strbuf_getline when it's in EOF state.
Also no longer automagically strbuf_release the buffer, it's counter
intuitive and breaks fast-import in a very subtle way.
Note: being at EOF implies that command_buf.len == 0.

* Add strbuf_rtrim to remove trailing spaces.
* Add strbuf_insert to insert data at a given position.
* Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
\0 so the overflow test for snprintf is the strict comparison. This is
not critical as the growth mechanism chosen will always allocate _more_
memory than asked, so the second test will not fail. It's some kind of
miracle though.
* Add size extension hints for strbuf_init and strbuf_read. If 0, default
applies, else:
+ initial buffer has the given size for strbuf_init.
+ first growth checks it has at least this size rather than the
default 8192.

Make every builtin-*.c file #include "builtin.h".
Also takes care of some declaration/definition mismatches.

When defined, this allows plumbing commands that update the
index (add, apply, checkout-index, merge-recursive, mv,
read-tree, rm, update-index, and write-tree) to write their
resulting index to an alternative index file while holding a
lock to the original index file. With this, git-commit that
jumps the index does not have to make an extra copy of the index
file, and more importantly, it can do the update while holding
the lock on the index.
However, I think the interface to let an environment variable
specify the output is a mistake, as shown in the documentation.
If a curious user has the environment variable set to something
other than the file GIT_INDEX_FILE points at, almost everything
will break. This should instead be a command line parameter to
tell these plumbing commands to write the result in the named
file, to prevent stupid mistakes.

This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily. Leftover from this will be fixed in a separate step, including
idiotic conversions like
if (!strncmp("foo", arg, 3))
=>
if (!(-prefixcmp(arg, "foo")))
This was done by using this script in px.perl
#!/usr/bin/perl -i.bak -p
if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
}
if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
}
and running:
$ git grep -l strncmp -- '*.c' | xargs perl px.perl

According to sys/paramh.h it's a "BSD name" for values defined in
<limits.h>. Besides PATH_MAX seems to be more commonly used.
