Add support for a new attribute, specfile. Files marked as being
specfiles are expanded by git-archive when they are written to an
archive. It has no effect on worktree files. The same placeholders
as those for the option --pretty=format: of git-log et al. can be
used.
The attribute is useful for creating auto-updating specfiles. It is
limited by the underlying function format_commit_message(), though.
E.g. currently there is no placeholder for git-describe like output,
and expanded specfiles can't contain NUL bytes. That can be fixed
in format_commit_message() later and will then benefit users of
git-log, too.

As noted by Johan Herland, git-archive is a kind of checkout and needs
to apply any checkout filters that might be configured.
This patch adds the convenience function convert_sha1_file which returns
a buffer containing the object's contents, after converting, if necessary
(i.e. it's a combination of read_sha1_file and convert_to_working_tree).
Direct calls to read_sha1_file in git-archive are then replaced by calls
to convert_sha1_file.
Since convert_sha1_file expects its path argument to be NUL-terminated --
a convention it inherits from convert_to_working_tree -- the patch also
changes the path handling in archive-tar.c to always NUL-terminate the
string. It used to solely rely on the len field of struct strbuf before.
archive-zip.c already NUL-terminates the path and thus needs no such
change.

Both archive-tar and archive-zip needed to be taught about subprojects.
The tar function died when trying to read the subproject commit object,
while the zip function reported "unsupported file mode".
This fixes both by representing the subproject as an empty directory.

We currently have two parallel notation for dealing with object types
in the code: a string and a numerical value. One of them is obviously
redundent, and the most used one requires more stack space and a bunch
of strcmp() all over the place.
This is an initial step for the removal of the version using a char array
found in object reading code paths. The patch is unfortunately large but
there is no sane way to split it in smaller parts without breaking the
system.

In order to make the generated tar files more friendly to users who
extract them as root using GNU tar and its implied -p option, change
the default umask to 002 and change the owner name and group name to
root. This ensures that a) the extracted files and directories are
not world-writable and b) that they belong to user and group root.
Before they would have been assigned to a user and/or group named
git if it existed. This also answers the question in the removed
comment: uid=0, gid=0, uname=root, gname=root is exactly what we
want.
Normal users who let tar apply their umask while extracting are
only affected if their umask allowed the world to change their
files (e.g. a umask of zero). This case is so unlikely and strange
that we don't need to support it.

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

This patch doesn't change any functionality, it only moves code around. It
makes seeing the few remaining lines of git-tar-tree code easier. ;-)
