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.

a92678b5f1 Do not unnecessarily strdup() environment variables
This reverts the memory duplication introduced in commit 60a2627, while
keeping everything else that has been cleaned up. The environment
variables are never modified, so we do not need to call xstrdupn() here.

Also, remove xstrdupn() which is no longer needed.

996f86e664 Return const char * in cgit_{httpscheme, hosturl, rooturl}()
The return values of these functions are essentially constant and should
never be modified.

Note that this will introduce a compiler warning when we try to free the
return value of any of these functions. However, given that all of these
currently return statically allocated strings in some cases, they need
to be refactored before this can be done anyway.

849ecd961d Update git to v1.8.2.1
This requires a small change to how we handle notes, but otherwise just
works.

Note that we can't use anything from v1.8.0 until v1.8.2.1 because some
of the symbols that we need for graph drawing were made private in
v1.8.0 and this was not reverted until v1.8.2.1.

1c32e008c8 ui-blob: don't segfault when no path is given
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
still causes strlen to be run on a null pointer.  Fix this.

This error was introduced by commit c1633c6 (Update git to v1.7.6.5 -
2013-03-02).

977a3ad7bf ui-summary.c: Move urls variable into print_urls()
There's no need for this variable to be global. Printing the header in
print_urls() instead of print_url() allows for moving this variable into
print_urls() without having to pass any status to print_url().

Note that this only works as long as we don't call print_urls() more
than once.

6d7e3596eb html: check return value of write
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.

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.

6d8a789d61 ui-shared: fix return type of cgit_self_link
cgit_self_link() is a void function but implements each case it handles
by doing "return <another_void_function>" which is not valid C; section
6.8.6.4 of C11 says:

	A return statement with an expression shall not appear in a
	function whose return type is void.

Fix this by removing the return keywords and converting the final code
block into an "else".

fb5a37317d ui-tree.c: Pass current revision to print_object()
No longer access the global curr_rev variable in print_object().

This will make it easier to squash the curr_rev variable into a context
structure without having to pass the context to the print_object()
function.

b1db30cd25 ui-plain.c: Use a context structure in walk_tree()
Do not misuse global variables to save the context. Instead, use the
context pointer which was designed to share information between a
read_tree_fn and the caller.

a6317505ea ui-plain.c: Do not access match variable in print_*()
Move all code setting the match variable to walk_tree().

This allows for easily moving this variable into a context structure
without having to pass the context to print_*().

41f9c4e2f6 ui-blob.c: Use a context structure in walk_tree()
Do not misuse global variables to save the context. Instead, use the
context pointer which was designed to share information between a
read_tree_fn and the caller.

This also prevents from potential misuse of the global pointers
match_path and matched_sha1 after the referenced values have been
overwritten on the stack.

973deda0ea ui-snapshot.c: Fill argv[0] with dummy.
parse_archive_args does not pass PARSE_OPT_KEEP_ARGV0 to parse_args,
which means the first argument will be discarded, as though it were a
function being called from the command-line. Thus, we fill argv[0] with
a dummy argument to prevent this from happening.
