This adds test for unpacking deltified objects with --strict option.
- unpacking full trees with --strict should pass;
- unpacking only trees with --strict should be rejected due to
missing blobs;
- unpacking only trees with --strict into an existing
repository with necessary blobs should succeed.

This patch introduces a strict mode, which ensures that:
- no malformed object will be written
- no object with broken links will be written
The patch ensures this by delaying the write of all non blob object.
These object are written, after all objects they link to are written.
An error can only result in unreferenced objects.

The new option --rebasing is used internally for rebase to tell am that
it is being used for its purpose. This would leave .dotest/rebasing to
help "completion" scripts tell if the ongoing operation is am or rebase.
Also the option at the same time stands for --binary, -3 and -k which
are always given when rebase drives am as its backend.
Using the information "am" leaves, git-completion.bash tells ongoing
rebase and am apart.

ba002f3 (builtin-fsck: move common object checking code to fsck.c) did
more than what it claimed to. Most notably, it wrongly made an empty tree
object an error by pretending to only move code from fsck_tree() in
builtin-fsck.c to fsck_tree() in fsck.c, but in fact adding a bogus check
to barf on an empty tree.
An empty tree object is _unusual_. Recent porcelains try reasonably hard
not to let the user create a commit that contains such a tree. Perhaps
warning about them in git-fsck may have some merit.
HOWEVER.
Being unusual and being errorneous are two quite different things. This
is especially true now we seem to use the same fsck_$object() code in
places other than git-fsck itself. For example, receive-pack should not
reject unusual objects, even if it would be a good idea to tighten it to
reject incorrect ones.

If the remote peer upload-pack process supports the include-tag
protocol extension then we can avoid running a second fetch cycle
on the client side by letting the server send us the annotated tags
along with the objects it is packing for us. In the following graph
we can now fetch both "tag1" and "tag2" on the same connection that
we fetched "master" from the remote when we only have L available
on the local side:
T - tag1 S - tag2
/ /
L - o ------ o ------ B
\ \
\ \
origin/master master
The objects for "tag1" are implicitly downloaded without our direct
knowledge. The existing "quickfetch" optimization within git-fetch
discovers that tag1 is complete after the first connection and does
not open a second connection.

The new protocol extension "include-tag" allows the client side
of the connection (fetch-pack) to request that the server side of the
native git protocol (upload-pack / pack-objects) use --include-tag
as it prepares the packfile, thus ensuring that an annotated tag object
will be included in the resulting packfile if the object it refers to
was also included into the packfile.

The new option "--include-tag" allows the caller to request that
any annotated tag be included into the packfile if the object the tag
references was also included as part of the packfile.
This option can be useful on the server side of a native git transport,
where the server knows what commits it is including into a packfile to
update the client. If new annotated tags have been introduced then we
can also include them in the packfile, saving the client from needing
to request them through a second connection.
This change only introduces the backend option and provides a test.
Protocol extensions to make this useful in fetch-pack/upload-pack
are still necessary to activate the logic during transport.

Back in 212945d4 ("Teach git-describe to verify annotated tag names

stored under in this repository's ref namespace.
This test case verifies this is working correctly by renaming the ref
for an annotated tag to a different name that what is recorded in the
tag body, and verifying that tag is returned. We also verify there is
a message shown on stderr to inform the user that the tag is possibly
stored under the wrong name locally.

git-merge used to use either the --squash,--no-squash, --no-ff,--ff,
--no-commit,--commit option, whichever came last in the command line.
This lead to some un-intuitive behavior, having
git merge --no-commit --no-ff <branch>
actually commit the merge. Now git-merge respects --no-commit together
with --no-ff, as well as other combinations of the options. However,
this broke a selftest in t/t7600-merge.sh which expected to have --no-ff
completely override the --squash option, so that
git merge --squash --no-ff <branch>
fast-forwards, and makes a merge commit; combining --squash with --no-ff
doesn't really make sense though, and is now refused by git-merge. The
test is adapted to test --no-ff without the preceding --squash, and
another test is added to make sure the --squash --no-ff combination is
refused.

Some callers may find it useful if "git describe" always gave back a
string that can be used as a shorter name for a commit object, rather than
checking its exit status (while squelching its error message, which could
potentially talk about more grave errors that should not be squelched) and
implementing a fallback themselves.
This teaches describe/name-rev a new option, --always, to use an
abbreviated object name when no tags or refs to use is found.

If the situation is the following on the remote and L is the common
base between both sides:
T - tag1 S - tag2
/ /
L - A - O - O - B
\ \
origin/master master
and we have decided to fetch "master" to acquire the range L..B we
can also nab tag S at the same time during the first connection,
as we can clearly see from the refs advertised by upload-pack that
S^{} = B and master = B.
Unfortunately we still cannot nab T at the same time as we are not
able to see that T^{} will also be in the range implied by L..B.
Such computations must be performed on the remote side (not yet
supported) or on the client side as post-processing (the current
behavior).
This optimization is an extension of the previous one in that it
helps on projects which tend to publish both a new commit and a
new tag, then lay idle for a while before publishing anything else.
Most followers are able to download both the new commit and the new
tag in one connection, rather than two. git.git tends to follow
such patterns with its roughly once-daily updates from Junio.
A protocol extension and additional server side logic would be
necessary to also ensure T is grabbed on the first connection.

If autofollowing of tags is enabled, we see a new tag on the remote
that we don't have, and we already have the SHA-1 object that the
tag is peeled to, then we can fetch the tag while we are fetching
the other objects on the first connection.
This is a slight optimization for projects that have a habit of
tagging a release commit after most users have already seen and
downloaded that commit object through a prior fetch session. In
such cases the users may still find new objects in branch heads,
but the new tag will now also be part of the first pack transfer
and the subsequent connection to autofollow tags is not required.
Currently git.git does not benefit from this optimization as any
release usually gets a new commit at the same time that it gets a
new release tag, however git-gui.git and many other projects are
in the habit of tagging fairly old commits.
Users who did not already have the tagged commit still require
opening a second connection to autofollow the tag, as we are unable
to determine on the client side if $tag^{} will be sent to the
client during the first transfer or not. Such computation must be
performed on the remote side of the connection and is deferred to
another series of changes.

The previous code mistakenly used wt_status_prepare to check whether the

The correct way with wt_status_* would be to call wt_status_print with the

both examining the working tree and spewing status information to nowhere.
