This teaches @{upstream} syntax to interpret_branch_name(), instead
of dwim_ref() machinery.
There are places in git UI that behaves differently when you give a local
branch name and when you give an extended SHA-1 expression that evaluates
to the commit object name at the tip of the branch. The intent is that
the special syntax such as @{-1} can stand in as if the user spelled the
name of the branch in such places.
The name of the branch "frotz" to switch to ("git checkout frotz"), and
the name of the branch "nitfol" to fork a new branch "frotz" from ("git
checkout -b frotz nitfol"), are examples of such places. These places
take only the name of the branch (e.g. "frotz"), and they are supposed to
act differently to an equivalent refname (e.g. "refs/heads/frotz"), so
hooking the @{upstream} and @{-N} syntax to dwim_ref() is insufficient
when we want to deal with cases a local branch is forked from another
local branch and use "forked@{upstream}" to name the forkee branch.
The "upstream" syntax "forked@{u}" is to specify the ref that "forked" is
configured to merge with, and most often the forkee is a remote tracking
branch, not a local branch. We cannot simply return a local branch name,
but that does not necessarily mean we have to returns the full refname
(e.g. refs/remotes/origin/frotz, when returning origin/frotz is enough).
This update calls shorten_unambiguous_ref() to do so.

This adds a few more tests that exercises @{upstream} syntax by commands
that operate differently when they are given branch name as opposed to a
refname (i.e. where "master" and "refs/heads/master" makes a difference).

When switching to a different commit, we first see the named rev exists
as a commit using lookup_commit_reference_gently(), and set new.path to
a string "refs/heads/" followed by the name the user gave us (but after
taking into special short-hands like @{-1} == "previous branch" and
"@{upstream}" == "the branch we merge with" into account). If the
resulting string names an existsing ref, then we are switching to that
branch (and will be building new commits on top of it); otherwise we are
detaching HEAD at that commit.
When the "master..." syntax is used as a short-hand for "master...HEAD",
we do want to detach HEAD at the merge base. However, on Windows, when
asked if ".git/refs/heads/master..." exists, the filesystem happily says
"it does" when ".git/refs/heads/master" exists.
Work this issue around by first calling check_ref_format(new.path) to see
if the string can possibly be a valid ref under "refs/heads/", before
asking resolve_ref().
We used to run another lookup_commit_reference(rev) even though we know it
succeeded and we have a good commit in new.commit already; this has been
with us from 782c2d6 (Build in checkout, 2008-02-07), the first version we
had "git checkout" implemented in C. Drop it.

We need to update the index before hooks run when actually making a
commit, but we shouldn't have to write the index when running "status".
If we can, then we have already spent cycles to refresh the index and
it is a waste not to write it out, but it is not a disaster if we cannot
write it out. The main reason the user is running "git status" is to get
the "status", and refreshing the index is a mere side effect that we can
do without.

Previously, these variables were set before there was a chance to set
NO_CURL.
This made a difference only during 'make install', because by installing
$(REMOTE_CURL_ALIASES), the rule tries to access $(REMOTE_CURL_PRIMARY),
which was never installed. On Windows, this fails; on Unix, stale symbolic

This gets rid of the whole tree cache refresh. Instead only path that
we touch will get refreshed. We may still lstat() more than needed,
but it'd be better playing safe.
This potentially reduces a large number of lstat() on big trees. Take
gentoo-x86 tree for example, which has roughly 80k files:

The original patch that became cfe370c (grep: do not segfault when -f is
used, 2009-10-16), was made against "maint" or newer branch back then, but
the fix addressed the issue that was present as far as in 1.6.4 series.
The maintainer backported the patch to the 1.6.4 maintenance branch, but
failed to notice that the new tests assumed the setup done by the script
in "maint", which did quite a lot more than the same test script in 1.6.4
series, and the output didn't match the expected result.
This should fix it.

In the worst case is_submodule_modified() got called three times for
each submodule. The information we got from scanning the whole
submodule tree the first time can be reused instead.
New parameters have been added to diff_change() and diff_addremove(),
the information is stored in a new member of struct diff_filespec. Its
value is then reused instead of calling is_submodule_modified() again.
When no explicit "-dirty" is needed in the output the call to
is_submodule_modified() is not necessary when the submodules HEAD
already disagrees with the ref of the superproject, as this alone
marks it as modified. To achieve that, get_stat_data() got an extra
argument.

This makes "subtree" more orthogonal to the rest of recursive merge, so
that you can use subtree and ours/theirs features at the same time. For
example, you can now say:
git merge -s subtree -Xtheirs other
to merge with "other" branch while shifting it up or down to match the
shape of the tree of the current branch, and resolving conflicts favoring
the changes "other" branch made over changes made in the current branch.
It also allows the prefix used to shift the trees to be specified using
the "-Xsubtree=$prefix" option. Giving an empty prefix tells the command
to figure out how much to shift trees automatically as we have always
done. "merge -s subtree" is the same as "merge -s recursive -Xsubtree="
(or "merge -s recursive -Xsubtree").
Based on an old patch done back in the days when git-merge was a script;
Avery ported the script part to builtin-merge.c. Bugs in shift_tree()
