Often a fast-import stream builds a new commit on top of the
previous commit it built, and it often unconditionally emits a
"from" command to specify the first parent, which can be omitted in
such a case. This caused fast-import to forget the tree of the
previous commit and then re-read it from scratch, which was
inefficient. Optimize for this common case.

The "rev-parse --parseopt" mode parsed the option specification
and the argument hint in a strange way to allow '=' and other
special characters in the option name while forbidding them from
the argument hint. This made it impossible to define an option
like "--pair <key>=<value>" with "pair=key=value" specification,
which instead would have defined a "--pair=key <value>" option.

In a superproject some commands need to interact with submodules. They
need to query values from the .gitmodules file either from the worktree
of from certain revisions. At the moment this is quite hard since a
caller would need to read the .gitmodules file from the history and then
parse the values. We want to provide an API for this so we have one
place to get values from .gitmodules from any revision (including the
worktree).
The API is realized as a cache which allows us to lazily read
.gitmodules configurations by commit into a runtime cache which can then
be used to easily lookup values from it. Currently only the values for
path or name are stored but it can be extended for any value needed.
It is expected that .gitmodules files do not change often between
commits. Thats why we lookup the .gitmodules sha1 from a commit and then
either lookup an already parsed configuration or parse and cache an
unknown one for each sha1. The cache is lazily build on demand for each
requested commit.
This cache can be used for all purposes which need knowledge about
submodule configurations. Example use cases are:
* Recursive submodule checkout needs to lookup a submodule name from
its path when a submodule first appears. This needs be done before
this configuration exists in the worktree.
* The implementation of submodule support for 'git archive' needs to
lookup the submodule name to generate the archive when given a
revision that is not checked out.
* 'git fetch' when given the --recurse-submodules=on-demand option (or
configuration) needs to lookup submodule names by path from the
database rather than reading from the worktree. For new submodule it
needs to lookup the name from its path to allow cloning new
submodules into the .git folder so they can be checked out without
any network interaction when the user does a checkout of that
revision.

After running "git am --abort", and then running "git reset --hard",
files that were not modified would still be re-checked out.
This is because clean_index() in builtin/am.c mistakenly called the
read_tree() function, which overwrites all entries in the index,
including the stat info.
"git am --skip" did not seem to have this issue because am_skip() called
am_run(), which called refresh_cache() to update the stat info. However,
there's still a performance penalty as the lack of stat info meant that
refresh_cache() would have to scan all files for changes.
Fix this by using unpack_trees() instead to merge the tree into the
index, so that the stat info from the index is kept.

First, the current code in untracked_cache_invalidate_path() is wrong
because it can only handle paths "a" or "a/b", not "a/b/c" because
lookup_untracked() only looks for entries directly under the given
directory. In the last case, it will look for the entry "b/c" in
directory "a" instead. This means if you delete or add an entry in a
subdirectory, untracked cache may become out of date because it does not
invalidate properly. This is noticed by David Turner.
The second problem is about invalidation inside a fully untracked/excluded
directory. In this case we may have to invalidate back to root. See the
comment block for detail.

Previously, some calls lookup_untracked would pass a full path. But
lookup_untracked assumes that the portion of the path up to and
including to the untracked_cache_dir has been removed. So
lookup_untracked would be looking in the untracked_cache for 'foo' for
'foo/bar' (instead of just looking for 'bar'). This would cause
untracked cache corruption.
Instead, treat_directory learns to track the base length of the parent
directory, so that only the last path component is passed to
lookup_untracked.

Teach notes about a new "notes.<name>.mergeStrategy" option for
configuring the notes merge strategy when merging into
refs/notes/<name>. This option allows for the selection of merge
strategy for particular notes refs, rather than all notes ref merges, as
user may not want cat_sort_uniq for all refs, but only some. Note that
the <name> is the local reference we are merging into, not the remote
ref we merged from. The assumption is that users will mostly want to
configure separate local ref merge strategies rather than strategies
depending on which remote ref they merge from.
