This removes many uses of "fmt" which uses a fixed size static pool of
fixed size buffers. Instead of relying on these, we now pass around

This adds the fmtalloc helper, html_txtf, html_vtxtf, and html_attrf.
These takes a printf style format string like htmlf but escapes the
resulting string. The html_vtxtf variant takes a va_list whereas
html_txtf is variadic.

The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':
if (virtual_root[strlen(virtual_root) - 1] != '/')
Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'. Do this with a new
"ensure_end" helper.

print_tag_header() is only called from cgit_print_tags() -- the
conditional invocation in print_tag() is never executed since
print_tag() is only called by cgit_print_tags() which already executes
print_tag_header() before (resulting in the global variable being always
set in when the condition is evaluated).

While doing this, remove declarations from header files where the

Git calculates the dependency files to be included using a simply

The return values of these functions are essentially constant and should

It it possible to inspect blobs by specifying only the SHA-1, and CGit
provides links to do so, for example if a tag points directly at a blob.
In this case the path_items structure is never used, but creating it

This squelches a gcc warning. It's also correct that we check to see if
there are any partial or failed writes. For now, we just print a warning
to stderr. In the future, perhaps it will prove wise to exit(1) on
partial writes.
Since tail is initialized to 0, we will never get a warning on the last
if statement, but recent gcc complains anyway. So, we initialize len as
well. Future gcc versions should be able to optimize this out anyway.

If CGIT_VERSION is in CGIT_CFLAGS then a change in version (for example
because you have committed your changes) causes all of the CGit objects

We already have a global cgit_version which is set from the #define'd
CGIT_VERSION in cgit.c. Change ui-patch.c to use this so that we only

Signed-off-by: John Keeping <john@keeping.me.uk>
Git does quite a lot of platform-specific detection in its Makefile,
which can result in it defining preprocessor variables that are used in
its header files. If CGit does not define the same variables it can
result in different sizes of some structures in different places in the
same application.
For example, on Solaris Git uses it's "compat" regex library which has a
different sized regex_t structure than that available in the platform
regex.h. This has a knock-on effect on the size of "struct rev_info"
and leads to hard to diagnose runtime issues.
In order to avoid all of this, introduce a "cgit.mk" file that includes
Git's Makefile and make all of the existing logic apply to CGit's
objects as well. This is slightly complicated because Git's Makefile
must run in Git's directory, so all references to CGit files need to be
prefixed with "../".
In addition, OBJECTS is a simply expanded variable in Git's Makefile so
we cannot just add our objects to it. Instead we must copy the two
applicable rules into "cgit.mk". This has the advantage that we can
split CGit-specific CFLAGS from Git's CFLAGS and hence avoid rebuilding
all of Git whenever a CGit-specific value changes.
