Move initialization of log_all_ref_updates
The patches to prevent Porcelainish that require working tree
from doing any damage in a bare repository make a lot of sense,
and I want to make the is_bare_git_dir() function more reliable.
In order to allow the repository owner override the heuristic
implemented in is_bare_git_dir() if/when it misidentifies a
particular repository, it would make sense to introduce a new
configuration variable "[core] bare = true/false", and make
is_bare_git_dir() notice it.
The scripts would do a 'repo-config --bool --get core.bare' and
iff the command fails (i.e. there is no such variable in the
configuration file), it would use the heuristic implemented at
the script level [*1*].
However, setup_git_env() which is called a lot earlier than we
even read from the repository configuration currently makes a
call to is_bare_git_dir(), in order to change the default
setting for log_all_ref_updates. It somehow feels that this is
a hack.
By the way, [*1*] is another thing I hate about the current
config mechanism. "git-repo-config --get" does not know what
the possible configuration variables are, let alone what the
default values for them are. It allows us not to maintain a
centralized configuration table, which makes it easy to
introduce ad-hoc variables and gives a warm fuzzy feeling of
being modular, but my feeling is that it is turning out to be a
rather high price to pay for scripts.

Custom compression levels for objects and packs
Add config variables pack.compression and core.loosecompression ,
and switch --compression=level to pack-objects.
Loose objects will be compressed using core.loosecompression if set,
else core.compression if set, else Z_BEST_SPEED.
Packed objects will be compressed using --compression=level if seen,
else pack.compression if set, else core.compression if set,
else Z_DEFAULT_COMPRESSION. This is the "pack compression level".
Loose objects added to a pack undeltified will be recompressed
to the pack compression level if it is unequal to the current
loose compression level by the preceding rules, or if the loose
object was written while core.legacyheaders = true. Newly
deltified loose objects are always compressed to the current
pack compression level.
Previously packed objects added to a pack are recompressed
to the current pack compression level exactly when their
deltification status changes, since the previous pack data
cannot be reused.
In either case, the --no-reuse-object switch from the first
patch below will always force recompression to the current pack
compression level, instead of assuming the pack compression level
hasn't changed and pack data can be reused when possible.
This applies on top of the following patches from Nicolas Pitre:
[PATCH] allow for undeltified objects not to be reused
[PATCH] make "repack -f" imply "pack-objects --no-reuse-object"

Clean up work-tree handling
The old version of work-tree support was an unholy mess, barely readable,
and not to the point.
For example, why do you have to provide a worktree, when it is not used?
As in "git status". Now it works.
Another riddle was: if you can have work trees inside the git dir, why
are some programs complaining that they need a work tree?
IOW it is allowed to call
$ git --git-dir=../ --work-tree=. bla
when you really want to. In this case, you are both in the git directory
and in the working tree. So, programs have to actually test for the right
thing, namely if they are inside a working tree, and not if they are
inside a git directory.
Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was
specified, unless there is a repository in the current working directory.
It does now.
The logic to determine if a repository is bare, or has a work tree
(tertium non datur), is this:
--work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true,
which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR
ends in /.git, which overrides the directory in which .git/ was found.
In related news, a long standing bug was fixed: when in .git/bla/x.git/,
which is a bare repository, git formerly assumed ../.. to be the
appropriate git dir. This problem was reported by Shawn Pearce to have
caused much pain, where a colleague mistakenly ran "git init" in "/" a
long time ago, and bare repositories just would not work.
