Shortcut during git fetch for avoiding looping through all local refs
The FetchProcess needs to verify that all the refs received point
to objects that are reachable from the local refs, which could be
very expensive but is needed to avoid missing objects exceptions
because of broken chains.
When the local repository has a lot of refs (e.g. millions) and the
client is fetching a non-commit object (e.g. refs/sequences/changes in
Gerrit) the reachability check on all local refs can be very expensive
compared to the time to fetch the remote ref.
Example for a 2M refs repository:
- fetching a single non-commit object: 50ms
- checking the reachability of local refs: 30s
A ref pointing to a non-commit object doesn't have any parent or
successor objects, hence would never need to have a reachability check
done. Skipping the askForIsComplete() altogether would save the 30s
time spent in an unnecessary phase.

FetchCommand: fix fetchSubmodules to work on a Ref to a blob
FetchCommand#fetchSubmodules assumed that FETCH_HEAD can always be
parsed as a tree. This isn't true if it refers to a Ref referring to a
BLOB. This is e.g. used in Gerrit for Refs like refs/sequences/changes
which are used to implement sequences stored in git.

Allow the exclusions of refs prefixes from bitmap
When running a GC.repack() against a repository with over one
thousands of refs/heads and tens of millions of ObjectIds,
the calculation of all bitmaps associated with all the refs
would result in an unreasonable big file that would take up to
several hours to compute.
Test scenario: repo with 2500 heads / 10M obj Intel Xeon E5-2680 2.5GHz
Before this change: 20 mins
After this change and 2300 heads excluded: 10 mins (90s for bitmap)
Having such a large bitmap file is also slow in the runtime
processing and have negligible or even negative benefits, because
the time lost in reading and decompressing the bitmap in memory
would not be compensated by the time saved by using it.
It is key to preserve the bitmaps for those refs that are mostly
used in clone/fetch and give the ability to exlude some refs
prefixes that are known to be less frequently accessed, even
though they may actually be actively written.
Example: Gerrit sandbox branches may even be actively
used and selected automatically because its commits are very
recent, however, they may bloat the bitmap, making it ineffective.
A mono-repo with tens of thousands of developers may have
a relatively small number of active branches where the
CI/CD jobs are continuously fetching/cloning the code. However,
because Gerrit allows the use of sandbox branches, the
total number of refs/heads may be even tens to hundred
thousands.

PackWriterBitmapPreparer: do not include annotated tags in bitmap
The annotated tags should be excluded from the bitmap associated
with the heads-only packfile. However, this was not happening
because of the check of exclusion of the peeled object instead
of the objectId to be excluded from the bitmap.
When creating a bitmap for the above commit graph, before this
change all the commits are included (3 bitmaps), which is
incorrect, because all commits reachable from annotated tags
should not be included.
The heads-only bitmap should include only commit0 and commit1
but because PackWriterBitPreparer was checking for the peeled
pointer of tag1 to be excluded (commit2) which was not found in
the list of tags to exclude (annotated-tag1), the commit2 was
included, even if it wasn't reachable only from the head.
Add an additional check for exclusion of the original objectId
for allowing the exclusion of annotated tags and their pointed
commits. Add one specific test associated with an annotated tag
for making sure that this use-case is covered also.
Example repository benchmark for measuring the improvement:
# refs: 400k (2k heads, 88k tags, 310k changes)
# objects: 11M (88k of them are annotate tags)
# packfiles: 2.7G
Before this change:
GC time: 5h
clone --bare time: 7 mins
After this change:
GC time: 20 mins

Speedup GC listing objects referenced from reflogs
GC needs to get a ReflogReader for all existing refs to list all objects
referenced from reflogs. The existing Repository#getReflogReader method
accepts the ref name and then resolves the Ref to create a ReflogReader.
GC calling that for a huge number of Refs one by one is very slow. GC
first gets all Refs in bulk and then calls getReflogReader for each of
them.
Fix this by adding another getReflogReader method to Repository which
accepts a Ref directly.
This speeds up running JGit gc on a mirror clone of the Gerrit
repository from 15:36 min to 1:08 min. The repository used in this test
had 45k refs, 275k commits and 1.2m git objects.

Cache trustFolderStat/trustPackedRefsStat value per-instance
Instead of re-reading the config every time the methods using these
values were called, cache the config value at the time of instance
construction. Caching the values improves performance for each of the
method calls. These configs are set based on the filesystem storing the
repository and unlikely to change while an application is running.
Refresh 'objects' dir and retry if a loose object is not found
A new loose object may not be immediately visible on a NFS
client if it was created on another client. Refreshing the
'objects' dir and trying again can help work around the NFS
behavior.
Here's an E2E problem that this change can help fix. Consider
a Gerrit multi-primary setup with repositories based on NFS.
Add a new patch-set to an existing change and then immediately
fetch the new patch-set of that change. If the fetch is handled
by a Gerrit primary different that the one which created the
patch-set, then we sometimes run into a MissingObjectException
that causes the fetch to fail.
Currently, we always read packed-refs file when 'trustFolderStat'
is false. Introduce a new config 'trustPackedRefsStat' which takes
precedence over 'trustFolderStat' when reading packed refs. Possible
values for this new config are:
* always: Trust packed-refs file attributes
* after_open: Same as 'always', but refresh the file attributes of
packed-refs before trusting it
* never: Always read the packed-refs file
* unset: Fallback to 'trustFolderStat' to determine if the file
attributes of packed-refs can be trusted
Folks whose repositories are on NFS and have traditionally been
setting 'trustFolderStat=false' can now get some performance improvement
with 'trustPackedRefsStat=after_open' as it refreshes the file
attributes of packed-refs (at least on some NFS clients) before
considering it.
For example, consider a repository on NFS with ~500k packed-refs. Here
are some stats which illustrate the improvement with this new config
when reading packed refs on NFS:

Fix crashes on rare combination of file names
The NameConflictTreeWalk class is used in merge for iterating over
entries in commits. The class uses a separate iterator for each
commit's tree. In rare cases it can incorrectly report the same entry
twice. As a result, duplicated entries are added to the merge result
and later jgit throws an exception when it tries to process merge
result.
The problem appears only when there is a directory-file conflict for
the last item in trees. Example from the bug:
Commit 1:
* subtree - file
* subtree-0 - file
Commit 2:
* subtree - directory
* subtree-0 - file
Here the names are ordered like this:
"subtree" file <"subtree-0" file < "subtree" directory.
The NameConflictTreeWalk handles similar cases correctly if there are
other files after subtree... in commits - this is processed in the
AbstractTreeIterator.min function. Existing code has a special
optimization for the case, when all trees are pointed to the same
entry name - it skips additional checks. However, this optimization
incorrectly skips checks if one of trees reached the end.
The fix processes a situation when some trees reached the end, while
others are still point to an entry.

This can be useful in cases when we run programs which have exclusive
access to a Git repository and we know that locking loose refs is
unnecessary and just a performance loss.
PushCommand: allow users to disable use of bitmaps for push
Reachability bitmaps are designed to speed up the "counting objects"
phase of generating a pack during a clone or fetch. They are not
optimized for Git clients sending a small topic branch via "git push".
In some cases (see [1]), using reachability bitmaps during "git push"
can cause significant performance regressions.
Add PushCommand#setUseBitmaps(boolean) to allow users to tell "git push"
not to use bitmaps.

I/O redirection for the pre-push hook
Fix and complete the implementation of calling the pre-push hook.
Add the missing error stream redirect, and add the missing setters
in Transport and in PushCommand. In Transport, delay setting up a
PrePushHook such that it happens only on a push. Previously, the
hook was set up also for fetches.

PackParser: populate full size of the PackedObjectInfos
We need the full size of the objects to populate the object-size index
of a pack. This size is not always the one encoded in the object header
in the pack (e.g. for deltas).
Populate the full size of PackedObjectInfos in the PackParser, which is
invoked when receiving a pack e.g. in a push.
