Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g
