b539c5e8fb git-merge-one: new merge world order.
This does two things:

 - Use new --stage=2 option to create the working tree file with
   leading paths and correct permission bits using
   checkout-index, as before.

 - Make sure we do not confuse "merge" program when the file
   being merged has an unfortunate name, '-L'.

3bd348aeea checkout-index: allow checking out from higher stages.
The new option, --stage=<n>, lets you copy out from an unmerged,
higher stage.  This is to help the new merge world order during
a nontrivial merge.

9754563ca9 Use printf rather than echo -n.
On AIX, there is no -n option to the system's echo.  Instead,
it needs the '\c' control character.  We could replace
  echo -n "foo"
with
  echo -e "foo\c"
but printf is recommended by most man pages.  Tested on AIX
5.3, Solaris 8, and Debian.

[jc: futureproofed two instances that uses variable with '%s'
 so later feeding different messages would not break things too
 easily; others are emitting literal so whoever changes the
 literal ought to notice more easily so they are safe.]

a6da9395a5 [PATCH] Initial AIX portability fixes.
Added an AIX clause in the Makefile; that clause likely
will be wrong for any AIX pre-5.2, but I can only test
on 5.3.  mailinfo.c was missing the compat header file,
and convert-objects.c needs to define a specific
_XOPEN_SOURCE as well as _XOPEN_SOURCE_EXTENDED.

be61db922a git-merge-one-file: resurrect leading path creation.
Since we do not use git-update-index followed by
git-checkout-index -u to create the half-merged file on
conflicting case anymore, we need to make sure the leading
directories are created here.

Maybe a better solution would be to allow update-index to add to
higher stage, and checkout-index to extract from such, but that
is a change slightly bigger than I would like to have so close
to 1.0, so this should do for now.

8d69195124 Fix 5501 test
Not everybody can rely on /bin/sh to be sane, and we support
SHELL_PATH for that.  Use it.

mktemp(1) is not used anywhere else in the core git.  Do not
introduce dependency on it.

Not everybody's "which" gives a sane return value.  For example,
on Solaris 'which XXX' says "no XXX in /usr/bin /bin ..." and
exits with zero status.  The lesson here is to never use 'which'
in your scripts.

4050c0df8e Clean up compatibility definitions.
This attempts to clean up the way various compatibility
functions are defined and used.

 - A new header file, git-compat-util.h, is introduced.  This
   looks at various NO_XXX and does necessary function name
   replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
   Makefile.

 - Those function name replacements are removed from the Makefile.

 - Common features such as usage(), die(), xmalloc() are moved
   from cache.h to git-compat-util.h; cache.h includes
   git-compat-util.h itself.

1494e03888 sha1_file.c: make sure packs in an alternate odb is named properly.
We somehow ended up registering packs in alternate object
directories as "dir/object//pack/pack-*", which confusd the
update-server-info code very badly.  Also we did not attempt to
detect a mistake of listing the object directory itself as one
of the alternates. This does not lead to incorrect behaviour,
but is simply wasteful, so try to do so when we are trivially
able to.

d79374c7b5 [PATCH] daemon.c and path.enter_repo(): revamp path validation.
The whitelist of git-daemon is checked against return value from
enter_repo(), and enter_repo() used to return the value obtained
from getcwd() to avoid directory aliasing issues as discussed
earier (mid October 2005).

Unfortunately, it did not go well as we hoped.

For example, /pub on a kernel.org public machine is a symlink to
its real mountpoint, and it is understandable that the
administrator does not want to adjust the whitelist every time
/pub needs to point at a different partition for storage
allcation or whatever reasons.  Being able to keep using
/pub/scm as the whitelist is a desirable property.

So this version of enter_repo() reports what it used to chdir()
and validate, but does not use getcwd() to canonicalize the
directory name.  When it sees a user relative path ~user/path,
it internally resolves it to try chdir() there, but it still
reports ~user/path (possibly after appending .git if allowed to
do so, in which case it would report ~user/path.git).

What this means is that if a whitelist wants to allow a user
relative path, it needs to say "~" (for all users) or list user
home directories like "~alice" "~bob".  And no, you cannot say
/home if the advertised way to access user home directories are
~alice,~bob, etc.  The whole point of this is to avoid
unnecessary aliasing issues.

Anyway, because of this, daemon needs to do a bit more work to
guard itself.  Namely, it needs to make sure that the accessor
does not try to exploit its leading path match rule by inserting
/../ in the middle or hanging /.. at the end.  I resurrected the
belts and suspender paranoia code HPA did for this purpose.

This check cannot be done in the enter_repo() unconditionally,
because there are valid callers of enter_repo() that want to
honor /../; authorized users coming over ssh to run send-pack
and fetch-pack should be allowed to do so.
