IndexEventConsumer metrics are reported per index PackExt and reverse
indexes did not have one, so they were not included.
Now that there is a REVERSE_INDEX PackExt, enable reporting
IndexEventConsumer metrics for reverse indexes.

Keys used for identifying reverse indexes in the DfsBlockCache use a
custom subclass ForReverseIndex because there was no PackExt for them.
This conflates BlockCacheMetrics for reverse indexes with those for
packs, since the key falls back onto 0 when there is no extension.
Replace the custom ForReverseIndex with a DfsStreamKey usage to bring
keys for the new REVERSE_INDEX extension in line with INDEX and BITMAP
and separate reverse index and pack BlockCacheMetrics.

There is no reverse index PackExt because the reverse index is not currently
written to a file. This prevents fine-grained performance reporting for reverse
indexes, which will be useful when introducing a reverse index file and
observing performance changes.
Add a reverse index extension that matches the one in cgit
(9bf691b78c/Documentation/gitformat-pack.txt (L302))
in preparation for adding a reverse index file while observing
performance before and after.

The change If6da9833 moved the computation of SHA1 from the JVM's
JCE to a pure Java implementation with collision detection.
The extra security for public sites comes with a cost of slower
SHA1 processing compared to the native implementation in the JDK.
When JGit is used internally and not exposed to any traffic from
external or untrusted users, the extra cost of the pure Java SHA1
implementation can be avoided, falling back to the previous
native MessageDigest implementation.

448052dc2e made WorkTreeUpdater package visible which breaks API for
subclasses of ResolveMerger since they cannot access WorkTreeUpdater.
Fix this by moving WorkTreeUpdater into ResolveMerger as a nested class
and mark it protected so that subclasses can use it.

This is from SonarLint (rule.java:S4348)
Regex patterns should not be created needlessly:
When String::replaceAll is used, the first argument should be a real
regular expression. If it’s not the case, String::replace does exactly
the same thing as String::replaceAll without the performance drawback of
the regex.

Before this change JGit did not support the session-id capability
implemented by native Git in UploadPack. This change implements
advertising the capability from the server and parsing the session-id
received from the client during an UploadPack operation.
Enable the transfer.advertisesid config setting to advertise the
capability from the server. The client may send a session-id capability
in response. If received, the value from this is parsed and available
via the getClientSID method on the UploadPack object.
This change does not add the capability to send a session-id from the
JGit client.

The config setting to enable advertising the session-id capability is
currently read in the ReceivePack class. This change moves it to a
common location in the TransferConfig class so that it can be reused
in other places like UploadPack. TransferConfig is also a more logical
place for the setting as it resides in the `transfer` config section.
Set the transfer.advertisesid setting to true to send the session-id
capability to the client.

In protocol V0 the client capabilities are appended to the first line.
Parsing session-id is currently only supported during a ReceivePack
operation. This change will parse the client session-id capability if
it has been sent by the client.
If the server sends the session-id capability to the client. The client
may respond with a session ID of its own. FirstWant.fromLine will now
parse the ID and make it available via the getClientSID method.
This change does not add support to send the session-id capability from
the server. The change is necessary to support session-id in UploadPack.

Add another newBatchUpdate method in the RefDirectory where we can
control if the created PackedBatchRefUpdate will lock the loose refs or
not.
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.

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.

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.

Partial clones filter the objects to send by size calling
ObjectReader#getObjectSize per object. This method reads the object from
storage to get the size, which can be expensive.
Offer a #isNotLargerThan method. The default implementation reads the
object, but subclasses can override it with more efficient lookups (e.g.
adding an index).
isNotLargerThan gives implementors more options to optimize than
getObjectIndex (e.g. can be implemented storing only object over certain
size).
