get_remote_merge_branch with zero or one arguments returns the
upstream branch. But a detached HEAD does no have an upstream branch,
as it is not tracking anything. Handle this case testing the exit code
of "git symbolic-ref -q HEAD".

Since c85c792 (pull --rebase: be cleverer with rebased upstream
branches, 2008-01-26), "git pull --rebase" has used the reflog to try to
rebase from the old upstream onto the new upstream.
Make this work if the local repository is explicitly passed on the
command line as in 'git pull --rebase . foo'.

Some scripts are expected to be sourced instead of executed on their own.
Avoid some confusion by not marking them executable.
The executable bit was confusing the valgrind support of our test scripts,
which assumed that any executable without a #!-line should be intercepted
and run through valgrind. So during valgrind-enabled tests, any script
sourcing these files actually sourced the valgrind interception script
instead.

Expand get_remote_merge_branch to compute the tracking branch to merge
when called without arguments (or only the remote name). This allows
"git pull --rebase" without arguments (default upstream branch) to
work with a rebased upstream. With explicit arguments it already worked.
Also add a test to check for this case.

The only user of get_remote_refs_for_fetch was "git pull --rebase" and
it only wanted the tracking branch to be merge. So, add a simple
function (get_remote_merge_branch) with this new meaning.
No behavior changes. The new function behaves like the old code in
"git pull --rebase". In particular, it only works with the default
refspec mapping and with remote branches, not tags.

not only from the three defined: heads, tags and remotes.
Noticed when I tried to fetch the references created by git-p4-import.bat:
they are placed into separate namespace (refs/p4import/, to avoid showing
them in git-branch output). As canon_refs_list_for_fetch always prepended
refs/heads/ it was impossible, and annoying: it worked before. Normally,
the p4import references are useless anywhere but in the directory managed
by perforce, but in this special case the cloned directory was supposed
to be a backup, including the p4import branch: it keeps information about
where the imported perforce state came from.

This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like
[remote "local"]
url = .
fetch = refs/heads/*:refs/heads/*
Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names. The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.
To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'. In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations. In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.
The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created. Finally, it fixes a typo in git-checkout.sh.

This reverts commit 80c797764a.
Back when I committed this, it seemed to be a good idea. People
who always use remote tracking branches can optionally use the
local name they happen to use to specify what to merge, which meant
that I did not have to teach them why we use the name at the remote
side every time they are confused.
But allowing it seems to break other people's scripts. The real
solution is not to allow more ways to express the same thing, but
to educate people to use the right syntax.

When we are on a detached HEAD, there is no current branch.
There is no reason to leak the error messages to the end user
since this is a situation we expect to see.
This adds -q option to git-symbolic-ref to exit without issuing
an error message if the given name is not a symbolic ref.
By the way, with or without this patch, there currently is no
good way to tell failure modes between "git symbolic-ref HAED"

When your fetch configuration has only the wildcards, we would

We used to support specifying the top part of remote URL in
remotes and use that as a short-hand for the URL.
$ cat .git/remotes/jgarzik

$ git pull jgarzik/misc-2.6
This is confusing when somebody attempts to do this:
$ git pull origin/foo
which is not syntactically correct (unless you have origin/foo.git
repository) and should fail, but it resulted in a mysterious
access to the 'foo' subdirectory of the origin repository.
Which was what it was designed to do, but because this is an
oddball "feature" I suspect nobody uses, let's remove it.

This will not be backward compatible no matter how you cut it.

An earlier commit a71fb0a1 implemented much requested safety
valve to refuse "git pull" or "git pull origin" without explicit
refspecs from using the first set of remote refs obtained by
reading .git/remotes/origin file or branch.*.fetch configuration
variables to create a merge. The argument was that while on a
branch different from the default branch, it is often wrong to
merge the default remote ref suitable for merging into the master.
That is fine as a theory. But many repositories already in use
by people in the real world do not have any of the per branch
configuration crap. They did not need it, and they do not need
it now. Merging with the first remote ref listed was just fine,
because they had only one ref (e.g. 'master' from linux-2.6.git)
anyway.
So this changes the safety valve to be a lot looser. When "git
fetch" gets only one remote branch, the irritating warning would
not trigger anymore.
I think we could also make the warning trigger when branch.*.merge
is not specified for the current branch, but is for some other
branch. That is for another commit.

This reverts commit a71fb0a141.
The logic to decide when to refuse to use the default "first set of
refs fetched" for merge was utterly bogus.
In a repository that happily worked correctly without any of the
per-branch configuration crap did not have (and did not have to
have) any branch.<current>.merge. With that broken commit, pulling
from origin no longer would work.
The warning triggered even when running "git fetch" only
when resulting .git/FETCH_HEAD only contained
branches marked as 'not-for-merge'.

(2) Many command names with 'cache' in them are renamed with
