e83b51b4f6 filter: basic write hooking infrastructure
Filters can now call hook_write and unhook_write if they want to
redirect writing to stdout to a different function. This saves us from
potential file descriptor pipes and other less efficient mechanisms.

We do this instead of replacing the call in html_raw because some places
stdlib's printf functions are used (ui-patch or within git itself),
which has its own internal buffering, which makes it difficult to
interlace our function calls. So, we dlsym libc's write and then
override it in the link stage.

While we're at it, we move considerations of argument count into the
generic new filter handler.

9973ef0207 Use argv_array in place of vector
Instead of using our own vector implementation, use argv_array from Git
which has been specifically designed for dynamic size argv arrays.

Drop vector.h and vector.c which are no longer needed.

a5e4ad2d8b cgit.mk: fix dependency handling
Git calculates the dependency files to be included using a simply
expanded Makefile variable, so it does not include the CGit objects that
are added after that Makefile has been processed.

We therefore need to include the dependency files ourselves in order to
get the dependency calculations right.  Do this.

cfb77e97fa Makefile: re-include cgit.conf in cgit.mk
This avoids needed to export every variable that might be used in
cgit.mk from the top-level Makefile.

7669f7f730 cgit.mk: Use SHELL_PATH_SQ to run gen-version.sh
On some platforms (notably Solaris) /bin/sh doesn't support enough of
POSIX for gen-version.sh to run.  Git's Makefile provides SHELL_PATH_SQ
to address this issue so we just have to use it.

d6768a6709 cgit.mk: don't rebuild everything if CGIT_VERSION changes
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
to be rebuilt.  Avoid this by using EXTRA_CPPFLAGS to add the version
for only those files that are affected and make them depend on VERSION.

5f323c1ff4 Makefile: re-use Git's Makefile where possible
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.
