The function used by "git pull" to stop the user when the working
tree has changes is useful in other places.
Let's move it into a more prominent (and into an actually reusable)
spot: wt-status.[ch].

When converting the pull command to a builtin, the
require_clean_work_tree() function was renamed and the pull-specific
parts hard-coded.
This makes it impossible to reuse the code, so let's modify the code to
make it more similar to the original shell script again.
Note: when the hint "Please commit or stash them" was introduced first,
Git did not have the convention of continuing error messages in lower
case, but now we do have that convention, therefore we reintroduce this
hint down-cased, obeying said convention.

In cmd_pull(), when verifying that there are no changes preventing a
rebasing pull, we diligently pass the prefix parameter to the
die_on_unclean_work_tree() function which in turn diligently passes it
to the has_unstaged_changes() and has_uncommitted_changes() functions.
The casual reader might now be curious (as this developer was) whether
that means that calling `git pull --rebase` in a subdirectory will
ignore unstaged changes in other parts of the working directory. And be
puzzled that `git pull --rebase` (correctly) complains about those
changes outside of the current directory.
The puzzle is easily resolved: while we take pains to pass around the
prefix and even pass it to init_revisions(), the fact that no paths are
passed to init_revisions() ensures that the prefix is simply ignored.
That, combined with the fact that we will *always* want a *full* working
directory check before running a rebasing pull, is reason enough to
simply do away with the actual prefix parameter and to pass NULL
instead, as if we were running this from the top-level working directory
anyway.

"git clone --resurse-submodules --reference $path $URL" is a way to
reduce network transfer cost by borrowing objects in an existing
$path repository when cloning the superproject from $URL; it
learned to also peek into $path for presense of corresponding
repositories of submodules and borrow objects from there when able.
* sb/submodule-clone-rr:
clone: recursive and reference option triggers submodule alternates
clone: implement optional references
clone: clarify option_reference as required
clone: factor out checking for an alternate path
submodule--helper update-clone: allow multiple references

When `--recursive` and `--reference` is given, it is reasonable to
expect that the submodules are created with references to the submodules
of the given alternate for the superproject.
An initial attempt to do this was presented to the mailing list, which
used flags that are passed around ("--super-reference") that instructed
the submodule clone to look for a reference in the submodules of the
referenced superproject. This is not well thought out, as any further
`submodule update` should also respect the initial setup.
When a new submodule is added to the superproject and the alternate
of the superproject does not know about that submodule yet, we rather
error out informing the user instead of being unclear if we did or did
not use a submodules alternate.
To solve this problem introduce new options that store the configuration
for what the user wanted originally.

Allow the user to pass in multiple references to update_clone.
Currently this is only internal API, but once the shell script is
replaced by a C version, this is needed.
This fixes an API bug between the shell script and the helper.
Currently the helper accepts "--reference" "--reference=foo"
as a OPT_STRING whose value happens to be "--reference=foo", and
then uses
if (suc->reference)
argv_array_push(&child->args, suc->reference)
where suc->reference _is_ "--reference=foo" when invoking the
underlying "git clone", it cancels out.
With this change we omit one of the "--reference" arguments when
passing references from the shell script to the helper.

Collect extra per-file data for porcelain V2 format.
The output of `git status --porcelain` leaves out many
details about the current status that clients might like
to have. This can force them to be less efficient as they
may need to launch secondary commands (and try to match
the logic within git) to accumulate this extra information.
For example, a GUI IDE might want the file mode to display
the correct icon for a changed item (without having to stat
it afterwards).

Receive-pack feeds its input to either index-pack or

a sender is willing to provide. Let's allow an arbitrary

related problem that is not addressed by this patch.

Change the default behavior of git-format-patch to generate numbered
sequence of 0/1 and 1/1 when generating both a cover-letter and a single
patch. This standardizes the cover letter to have 0/N which helps
distinguish the cover letter from the patch itself. Since the behavior
is easily changed via configuration as well as the use of -n and -N this
should be acceptable default behavior.
Add tests for the new default behavior.

Since 3b75ee9 ("blame: allow to blame paths freshly added to the index",
2016-07-16) git blame also looks at the index to determine if there is a
file that was freshly added to the index.
cache_name_pos returns -pos - 1 in case there is no match is found, or
if the name matches, but the entry has a stage other than 0. As git
blame should work for unmerged files, it uses strcmp to determine
whether the name of the returned position matches, in which case the
file exists, but is merely unmerged, or if the file actually doesn't
exist in the index.
If the repository is empty, or if the file would lexicographically be
sorted as the last file in the repository, -cache_name_pos - 1 is
outside of the length of the active_cache array, causing git blame to
segfault. Guard against that, and die() normally to restore the old
behaviour.

Since 4804aab (help (Windows): Display HTML in default browser using
Windows' shell API, 2008-07-13), Git for Windows used to call
`ShellExecute()` to launch the default Windows handler for `.html`

The idea was to avoid going through a shell script, for performance
reasons.
However, this change ignores the `help.browser` config setting. Together
with browsing help not being a performance-critical operation, let's
just revert that patch.

"git blame file" allowed the lineage of lines in the uncommitted,
unadded contents of "file" to be inspected, but it refused when
"file" did not appear in the current commit. When "file" was
created by renaming an existing file (but the change has not been
committed), this restriction was unnecessarily tight.

Use the macro FLEX_ALLOC_MEM instead of open-coding it. This shortens
and simplifies the code a bit.

When "git rebase" tries to compare set of changes on the updated
upstream and our own branch, it computes patch-id for all of these
changes and attempts to find matches. This has been optimized by
lazily computing the full patch-id (which is expensive) to be
compared only for changes that touch the same set of paths.
* kw/patch-ids-optim:
rebase: avoid computing unnecessary patch IDs
patch-ids: add flag to create the diff patch id using header only data
patch-ids: replace the seen indicator with a commit pointer
patch-ids: stop using a hand-rolled hashmap implementation

The `rebase` family of Git commands avoid applying patches that were
already integrated upstream. They do that by using the revision walking
option that computes the patch IDs of the two sides of the rebase
(local-only patches vs upstream-only ones) and skipping those local
patches whose patch ID matches one of the upstream ones.
In many cases, this causes unnecessary churn, as already the set of
paths touched by a given commit would suffice to determine that an
upstream patch has no local equivalent.
This hurts performance in particular when there are a lot of upstream
patches, and/or large ones.
Therefore, let's introduce the concept of a "diff-header-only" patch ID,
compare those first, and only evaluate the "full" patch ID lazily.
Please note that in contrast to the "full" patch IDs, those
"diff-header-only" patch IDs are prone to collide with one another, as
adjacent commits frequently touch the very same files. Hence we now
have to be careful to allow multiple hash entries with the same hash.
We accomplish that by using the hashmap_add() function that does not even
test for hash collisions. This also allows us to evaluate the full patch ID
lazily, i.e. only when we found commits with matching diff-header-only
patch IDs.
We add a performance test that demonstrates ~1-6% improvement. In
practice this will depend on various factors such as how many upstream
changes and how big those changes are along with whether file system
caches are cold or warm. As Git's test suite has no way of catching
performance regressions, we also add a regression test that verifies
that the full patch ID computation is skipped when the diff-header-only
computation suffices.

"git mv dir non-existing-dir/" did not work in some environments
the same way as existing mainstream platforms. The code now moves
"dir" to "non-existing-dir", without relying on rename("A", "B/")
that strips the trailing slash of '/'.

When calling `rename("dir", "non-existing-dir/")` on Linux, it silently
succeeds, stripping the trailing slash of the second argument.
This is all good and dandy but this behavior disagrees with the specs at
http://pubs.opengroup.org/onlinepubs/9699919799/functions/rename.html
that state clearly regarding the 2nd parameter (called `new`):
If the `new` argument does not resolve to an existing directory
entry for a file of type directory and the `new` argument
contains at least one non- <slash> character and ends with one
or more trailing <slash> characters after all symbolic links
have been processed, `rename()` shall fail.
Of course, we would like `git mv dir non-existing-dir/` to succeed (and
rename the directory "dir" to "non-existing-dir"). Let's be extra
careful to remove the trailing slash in that case.
This lets t7001-mv.sh pass in Bash on Windows.

Call strbuf_add_unique_abbrev() to add abbreviated hashes to strbufs

buffer. This is shorter and a bit more efficient.

Call string_list_split() for cutting a space separated list into pieces
instead of reimplementing it based on struct strategy. The attr member
of struct strategy was not used split_merge_strategies(); it was a pure
string operation. Also be nice and clean up once we're done splitting;
the old code didn't bother freeing any of the allocated memory.
