Fix backwards-incompatible handling of core.sharedRepository
06cbe85 (Make core.sharedRepository more generic, 2008-04-16) broke the
traditional setting of core.sharedRepository to true, which was to make
the repository group writable: with umask 022, it would clear the
permission bits for 'other'. (umask 002 did not exhibit this behaviour
since pre-chmod() check in adjust_shared_perm() fails in that case.)
The call to adjust_shared_perm() should only loosen the permission.
If the user has umask like 022 or 002 that allow others to read, the
resulting files should be made readable and writable by group, without
restricting the readability by others.
This patch fixes the adjust_shared_perm() mode tweak based on Junio's
suggestion and adds the appropriate tests to t/t1301-shared-repo.sh.

A lot of modules that have nothing to do with git-shell functionality
were linked in, bloating git-shell more than 8 times.
This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
later self sufficient;
3. moving make_absolute_path into a new separate file.
The following numbers have been received with the default optimization
settings on master using GCC 4.1.2:

Once we find the absolute paths for git_dir and work_tree, we can make
git_dir a relative path since we know pwd will be work_tree. This should
save the kernel some time traversing the path to work_tree all the time
if git_dir is inside work_tree.
Daniel's patch didn't apply for me as-is, so I recreated it with some
differences, and here are the numbers from ten runs each.
There is some IO for me - probably due to more-or-less random flushing of
the journal - so the variation is bigger than I'd like, but whatever:
Before:
real 0m8.135s
real 0m7.933s
real 0m8.080s
real 0m7.954s
real 0m7.949s
real 0m8.112s
real 0m7.934s
real 0m8.059s
real 0m7.979s
real 0m8.038s
After:
real 0m7.685s
real 0m7.968s
real 0m7.703s
real 0m7.850s
real 0m7.995s
real 0m7.817s
real 0m7.963s
real 0m7.955s
real 0m7.848s
real 0m7.969s
Now, going by "best of ten" (on the assumption that the longer numbers
are all due to IO), I'm saying a 7.933s -> 7.685s reduction, and it does
seem to be outside of the noise (ie the "after" case never broke 8s, while
the "before" case did so half the time).
So looks like about 3% to me.
Doing it for a slightly smaller test-case (just the "arch" subdirectory)
gets more stable numbers probably due to not filling the journal with
metadata updates, so we have:
Before:
real 0m1.633s
real 0m1.633s
real 0m1.633s
real 0m1.632s
real 0m1.632s
real 0m1.630s
real 0m1.634s
real 0m1.631s
real 0m1.632s
real 0m1.632s
After:
real 0m1.610s
real 0m1.609s
real 0m1.610s
real 0m1.608s
real 0m1.607s
real 0m1.610s
real 0m1.609s
real 0m1.611s
real 0m1.608s
real 0m1.611s
where I'ld just take the averages and say 1.632 vs 1.610, which is just
over 1% peformance improvement.
So it's not in the noise, but it's not as big as I initially thought and
measured.
(That said, it obviously depends on how deep the working directory path is
too, and whether it is behind NFS or something else that might need to
cause more work to look up).

Particularly for the "alternates" file, if one will be created, we
want a path that doesn't depend on the current directory, but we want
to retain any symlinks in the path as given and any in the user's view
of the current directory when the path was given.

Make git recognize a new environment variable that prevents it from
chdir'ing up into specified directories when looking for a GIT_DIR.
Useful for avoiding slow network directories.
For example, I use git in an environment where homedirs are automounted
and "ls /home/nonexistent" takes about 9 seconds. Setting
GIT_CEILING_DIRS="/home" allows "git help -a" (for bash completion) and
"git symbolic-ref" (for my shell prompt) to run in a reasonable time.

git init --shared=0xxx, where '0xxx' is an octal number, will create
a repository with file modes set to '0xxx'. Users with a safe umask
value (0077) can use this option to force file modes. For example,
'0640' is a group-readable but not group-writable regardless of
user's umask value. Values compatible with old Git versions are written
as they were before, for compatibility reasons. That is, "1" for
"group" and "2" for "everybody".
"git config core.sharedRepository 0xxx" is also handled.

git_install_prefix() returns the install prefix of msysgit. For
all other architectures it returns "". The path returned contains
slashes.
make_native_separator() takes a unix path (slashes) and converts
the separators in place. On Windows slashes are converted to
backslashes.
All the code was available in help.c and is now moved to path.c.

We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime. Likewise we should always be
treating unsigned values as unsigned values, not as signed values.
Most of these are very straightforward. The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case. Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

This allows "git checkout v1.4.3" to dissociate the HEAD of
repository from any branch. After this point, "git branch"
starts reporting that you are not on any branch. You can go
back to an existing branch by saying "git checkout master", for
example.
This is still experimental. While I think it makes sense to
allow commits on top of detached HEAD, it is rather dangerous
unless you are careful in the current form. Next "git checkout
master" will obviously lose what you have done, so we might want
to require "git checkout -f" out of a detached HEAD if we find
that the HEAD commit is not an ancestor of any other branches.
There is no such safety valve implemented right now.
On the other hand, the reason the user did not start the ad-hoc
work on a new branch with "git checkout -b" was probably because
the work was of a throw-away nature, so the convenience of not
having that safety valve might be even better. The user, after
accumulating some commits on top of a detached HEAD, can always
create a new branch with "git checkout -b" not to lose useful
work done while the HEAD was detached.
We'll see.

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).
