The merge functions duplicate entries as needed and they don't free
them. Release them in unpack_nondirectories, the same function
where they were allocated, after we're done.
As suggested by Felipe, use the same loop style (zero-based for loop)
for freeing as for allocating.

Change the type merge_fn_t to accept the array of cache_entry pointers
as const pointers to const pointers. This documents the fact that the
merge functions don't modify the cache_entry contents or replace any of
the pointers in the array.
Only a single cast is necessary in unpack_nondirectories because adding
two const modifiers at once is not allowed in C. The cast is safe in
that it doesn't mask any modfication; call_unpack_fn only needs the
array for reading.

Duplicate the merge entry right away and work with that instead of
modifying the entry we got and duplicating it only at the end of
the function. Then mark that pointer const to document that we
don't modify the referenced cache_entry.
This change is safe because all existing merge functions call
merged_entry just before returning (or not at all), i.e. they don't
care about changes to the referenced cache_entry after the call.
unpack_nondirectories and unpack_index_entry, which call the merge
functions through call_unpack_fn, aren't interested in such changes
neither.
The change complicates merged_entry a bit because we have to free the
copy if we error out, but allows callers to pass a const pointer.

As of 95c6f271 "dir.c: unify is_excluded and is_path_excluded APIs", the
is_excluded API no longer recurses into directories that match an ignore
pattern, and returns the directory's ignored state for all contained paths.
This is OK for normal ignore patterns, i.e. ignoring a directory affects
the entire contents recursively.
Unfortunately, this also "works" for negated ignore patterns ('!dir'), i.e.
the entire contents is "not-ignored" recursively, regardless of ignore
patterns that match the contents directly.
In prep_exclude, skip recursing into a directory only if it is really
ignored (i.e. the ignore pattern is not negated).

Case folding is not done correctly when matching against the [:upper:]
character class and uppercased character ranges (e.g. A-Z).
Specifically, an uppercase letter fails to match against any of them
when case folding is requested because plain characters in the pattern
and the whole string are preemptively lowercased to handle the base case
fast.
That optimization is kept and ISLOWER() is used in the [:upper:] case
when case folding is requested, while matching against a character range
is retried with toupper() if the character was lowercase, as the bounds
of the range itself cannot be modified (in a case-insensitive context,
[A-_] is not equivalent to [a-_]).

There are some index handling subtleties in 'commit --only' that are
best tested when we have an existing index, but an unborn or empty
HEAD. These circumstances are easily produced by 'checkout --orphan',
but we did not previously have a test for it.
The main expected failure mode would be: erroneously loading the
existing index contents when building the temporary index that is used
for --only. Cf.

With this change, the output of the push (with push.default set to
current) changes subtly from:
$ git push
...
* [new branch] HEAD -> push-current-head
to:
$ git push
...
* [new branch] push-current-head -> push-current-head
This patch was written with a different motivation. There is a problem
unique to push.default = current:
# on branch push-current-head
$ git push
# on another terminal
$ git checkout master
# return to the first terminal
# the push tried to push master!
This happens because the 'git checkout' on the second terminal races
with the 'git push' on the first terminal. Although this patch does not
solve the core problem (there is still no guarantee that 'git push' on
the first terminal will resolve HEAD before 'git checkout' changes HEAD
on the second), it works in practice.

Setting push.default to current adds the refspec "HEAD" for the
transport layer to handle. If "HEAD" doesn't resolve to a branch (and
since no refspec rhs is specified), the push fails after some time with
a cryptic error message:
$ git push
error: unable to push to unqualified destination: HEAD
The destination refspec neither matches an existing ref on the remote nor
begins with refs/, and we are unable to guess a prefix based on the source ref.
error: failed to push some refs to 'git@github.com:artagnon/git'
Fail early with a nicer error message:
$ git push
fatal: You are not currently on a branch.
To push the history leading to the current (detached HEAD)
state now, use

However, the set of files to be copied back is computed

This new feature allows a rebase to be executed on a dirty worktree or
index. It works by creating a temporary "dangling merge commit" out
of the worktree and index changes (via 'git stash create'), and
automatically applying it after a successful rebase or abort.
rebase stores the SHA-1 hex of the temporary merge commit, along with
the rest of the rebase state, in either
.git/{rebase-merge,rebase-apply}/autostash depending on the kind of
rebase. Since $state_dir is automatically removed at the end of a
successful rebase or abort, so is the autostash.
The advantage of this approach is that we do not affect the normal
stash's reflogs, making the autostash invisible to the end-user. This
means that you can use 'git stash' during a rebase as usual.
When the autostash application results in a conflict, we push
$state_dir/autostash onto the normal stash and remove $state_dir
ending the rebase. The user can inspect the stash, and pop or drop at
any time.
Most significantly, this feature means that a caller like pull (with
pull.rebase set to true) can easily be patched to remove the
require_clean_work_tree restriction.
