Sometimes users want to report a bug they experience on their
repository, but they are not at liberty to share the contents of
the repository. "fast-export" was taught an "--anonymize" option

The number of refs that can be pushed at once over smart HTTP was
limited by the command line length. The limitation has been lifted

Fsck tries hard to detect missing objects, and will complain
(and exit non-zero) about any inter-object links that are
missing. However, it will not exit non-zero for any missing
ref tips, meaning that a severely broken repository may
still pass "git fsck && echo ok".
The problem is that we use for_each_ref to iterate over the
ref tips, which hides broken tips. It does at least print an
error from the refs.c code, but fsck does not ever see the
ref and cannot note the problem in its exit code. We can solve
this by using for_each_rawref and noting the error ourselves.
In addition to adding tests for this case, we add tests for
all types of missing-object links (all of which worked, but
which we were not testing).

When fsck'ing an incoming pack, we need to fsck objects that cannot be
read via read_sha1_file() because they are not local yet (and might even
be rejected if transfer.fsckobjects is set to 'true').
For commits, there is a hack in place: we basically cache commit
objects' buffers anyway, but the same is not true, say, for tag objects.
By refactoring fsck_object() to take the object buffer and size as
optional arguments -- optional, because we still fall back to the
previous method to look at the cached commit objects if the caller
passes NULL -- we prepare the machinery for the upcoming handling of tag
objects.
The assumption that such buffers are inherently NUL terminated is now
wrong, of course, hence we pass the size of the buffer so that we can
add a sanity check later, to prevent running past the end of the buffer.

Making the strbuf local in each function that needs to print errors
saves the reader from having to think about action at a distance,
such as
* errors piling up and being concatenated with no newline between
them
* errors unhandled in one function, to be later handled in another
* concurrency issues, if this code starts using threads some day
No functional change intended.

Wrap all the ref updates inside a transaction.
In the new API there is no distinction between failure to lock and
failure to write a ref. Both can be permanent (e.g., a ref
"refs/heads/topic" is blocking creation of the lock file
"refs/heads/topic/1.lock") or transient (e.g., file system full) and
there's no clear difference in how the client should respond, so
replace the two statuses "failed to lock" and "failed to write" with
a single status "failed to update ref". In both cases a more
detailed message is sent by sideband to diagnose the problem.
Example, before:
error: there are still refs under 'refs/heads/topic'
remote: error: failed to lock refs/heads/topic
To foo
! [remote rejected] HEAD -> topic (failed to lock)
After:
error: there are still refs under 'refs/heads/topic'
remote: error: Cannot lock the ref 'refs/heads/topic'.
To foo
! [remote rejected] HEAD -> topic (failed to update ref)

Add an err argument to _begin so that on non-fatal failures in future ref
backends we can report a nice error back to the caller.
While _begin can currently never fail for other reasons than OOM, in which
case we die() anyway, we may add other types of backends in the future.
For example, a hypothetical MySQL backend could fail in _begin with
"Can not connect to MySQL server. No route to host".
