Improve native Git transport when following repository
If the client is only following the remote repository and has not
created any new non-common commits, the client will wind up sending
a "have %s" line for each tag in the repository. For some projects
like git.git, this is 339 tags and growing, resulting in more than
16 KiB needing to be POSTed over 12 HTTP requests.
Teach UploadPack (server side) to always execute the okToGiveUp()
logic at least once per negotiation round to determine if the server
can compute a pack right now. If it can, shove in an "ACK %s ready"
message to tell the client this and try to prevent receiving ancient
tags in future negotiation rounds.
Teach BasePackFetchConnection (client side) to honor a "ACK %s ready"
from the remote and break out of its SEND_HAVE loop once the remote
knows it can create a pack. This avoids sending the remaining 307
tags of git.git.

ObjectIdOwnerMap: More lightweight map for ObjectIds
OwnerMap is about 200 ms faster than SubclassMap, more friendly to the
GC, and uses less storage: testing the "Counting objects" part of
PackWriter on 1886362 objects:
The major difference with OwnerMap is entries must extend from
ObjectIdOwnerMap.Entry, where the OwnerMap has injected its own
private "next" field into each object. This allows the OwnerMap to use
a singly linked list for chaining collisions within a bucket. By
putting collisions in a linked list, we gain the entire table back for
the SHA-1 bits to index their own "private" slot.
Unfortunately this means that each object can appear in at most ONE
OwnerMap, as there is only one "next" field within the object instance
to thread into the map. For types that are very object map heavy like
RevWalk (entity RevObject) and PackWriter (entity ObjectToPack) this
is sufficient, these entity types are only put into one map by their
container. By introducing a new map type, we don't break existing
applications that might be trying to use ObjectIdSubclassMap to track
RevCommits they obtained from a RevWalk.
The OwnerMap uses less memory. Each object uses 1 reference more (so
we're up 1,886,362 references), but the table is 1/2 the size (2^20
rather than 2^21). The table itself wastes only 210,790 slots, rather
than 2,307,942. So OwnerMap is wasting 200k fewer references.
OwnerMap is more friendly to the GC, because it hardly ever generates
garbage. As the map reaches its 100% load factor target, it doubles in
size by allocating additional segment arrays of 2048 entries. (So the
first grow allocates 1 segment, second 2 segments, third 4 segments,
etc.) These segments are hooked into the pre-allocated directory of
1024 spaces. This permits the map to grow to 2 million objects before
the directory itself has to grow. By using segments of 2048 entries,
we are asking the GC to acquire 8,204 bytes in a 32 bit JVM. This is
easier to satisfy then 2,307,942 bytes (for the 512k table that is
just an intermediate step in the SubclassMap). By reusing the
previously allocated segments (they are re-hashed in-place) we don't
release any memory during a table grow.
When the directory grows, it does so by discarding the old one and
using one that is 4x larger (so the directory goes to 4096 entries on
its first grow). A directory of size 4096 can handle up to 8 millon
objects. The second directory grow (16384) goes to 33 million objects.
At that point we're starting to really push the limits of the JVM
heap, but at least its many small arrays. Previously SubclassMap would
need a table of 67108864 entries to handle that object count, which
needs a single contiguous allocation of 256 MiB. That's hard to come
by in a 32 bit JVM. Instead OwnerMap uses 8192 arrays of about 8 KiB
each. This is much easier to fit into a fragmented heap.

PackWriter: Don't reuse commit or tag deltas
JGit doesn't generate deltas for commit or tag objects when it packs
a repository from scratch. This is an explicit design decision that
is (mostly) justified by the fact that these objects do not delta
compress well.
Annotated tags are made once on stable points of the project history,
it is unlikely they will ever appear again with sufficient common
text to justify using a delta over just deflating the raw content.
JGit never tries to delta compress annotated tags and I take the
stance that these are best stored as non-deltas given how frequently
they might be accessed by repository viewers.
Commits only have sufficient common text when they are cherry-picked
to forward-port or back-port a change from one branch to another.
Even in these cases the distance between the commits as returned
by the log traversal has to be small enough that they would both
appear in the delta search window at the same time in order to
delta compress one of the messages against the other. JGit never
tries to delta compress commits, as it requires a lot of CPU time
but typically does not produce a smaller pack file.
Avoid reusing deltas for either of these types when constructing a
new pack. To avoid killing performance during serving of network
clients, UploadPack disables this code change by allowing PackWriter
to reuse delta commits. Repositories that were already repacked by
C Git will not have their delta commits decompressed and recompressed
on the fly during object writing, saving server-side CPU resources.

searched when their containing pack was generated and they were

The isReuseAsIs() flag is checked before isDoNotDelta() because it

RevWalk: Don't release during inMergeBase()
In bc1af8459e ("RevWalk: Don't reset ObjectReader when stopping") we
stopped releasing the reader when the current log traversal is over.
This should have also been applied to the merge base logic that is
buried within MergeGenerator, but got missed.

PackWriter: Add missing timers to Statistics
We did not record the time spent on the object reuse search or the
object size lookup, both of which occur between the counting phase and
the compressing phase. If there are enough objects involved, these
times can be significant so its worth timing them and recording it.

Show notes in Log CLI command
Support for --no-standard-notes and --show-notes=REF options is added
to the Log command. The --show-notes option can be specified more than
once if more than one notes branch should be used for showing notes.
The notes are displayed from note branches in the order how the note
branches are specified in the command line. However, the standard note,
from the refs/notes/commits, is always displayed as first unless
the --no-standard-notes options is given.
