This introduces ReftableBatchRefUpdate and ReftableDatabase, as
generic classes, with some code moved to DfsReftableBatchRefUpdate and
DfsReftableDatabase.
Clarify thread-safety requirements by asserting locked status in
accessors, and acquiring locks in callers. This does not fix threading
problems, because ReftableBatchRefUpdate already wraps the whole
transaction in a lock.
This also fixes a number of bugs in ReftableBatchRefUpdate:
* non-atomic updates should not bail on first failure
* isNameConflicting should also check for conflicts between names that
are added and removed in the BatchRefUpdate.

reftable: fix lookup by ID in merged reftables
On changing a ref, the old SHA1 is not updated in the object => ref
mapping. This means search by object ID may still turn up a ref from
deeper within the stack. To fix this, check all refs produced by the
merged iterator against the merged reftables.
The flag enabling sideband-all is used in two places: in UploadPack
for advertisement and in the protocol parser to read it from the
request.
This leds to problems in distributed deployments where the two requests of
a fetch can go to different servers with different configurations.
Use the existing allowsidebandall to accept the sideband-all request
(and respond to it) and introduce a new "advertisesidebandall" to toggle
the advertising of the feature.

http: Allow specifying a custom error handler for UploadPack
By abstracting the error handler, this lets a user customize the error
handler for UploadPack. A customized error handler can show a custom
error message to the clients based on the exception thrown from the
hook, create a monitoring system for server errors, or do custom
logging.
ErrorWriter writes an error message to the user. The implementation is
swapped once it detects that the client supports sideband. By default it
uses the protocol level ERR packet, which was introduced recently.
In total the error output is done in two different places;
UploadPack#upload and UploadPack#sendPack. These will be consolidated in
the next change.

Rename servlet-api-3_1 to match Gerrit master
JGit is built from source on Gerrit-CI: the Bazel build
dependencies need to be aligned. On Gerrit master the servlet-api-3_1
is renamed to servlet-api (see [1]): do the same on the JGit master
branch.
In addition, removing the version suffix from dependency rule makes
it much easier to upgrade. The actual reason the for the renaming it
in Gerrit core is upgrade attempt to servlet-api 4.0, done in [2].
MergedReftable is not used as an AutoCloseable, because closing tables
is currently handled by DfsReftableStack#close.
Encode that a MergedReftable is a list of ReftableReaders. The previous
code suggested that we could form nested trees of MergedReftables,
which is not how we use reftables.
Do not rely on ArrayIndexOutOfBoundsException to detect end of input
In the Config#StringReader we relied on ArrayIndexOutOfBoundsException
to detect the end of the input. Creation of exception with (deep) stack
trace can significantly degrade performance in case when we read
thousands of config files, like in the case when Gerrit reads all
external ids from the NoteDb.
Use the buf.length to detect the end of the input.

Bazel: Reuse version from .bazelversion for minimum used version check

That why minimum used Bazel version check is still needed in WORKSPACE

currently, bazel version is maintained in two places:
* .bazelversion
* WORKSPACE

WorkingTreeIterator: handle different timestamp resolutions
Older JGit stored only milliseconds timestamps in the index. Newer
JGit may get finer timestamps from the file system. This leads to
slow index diffs when a new JGit runs against an index produced
by older JGit because many timestamps will differ and JGit will
then do many content checks. See [1].
Handle this migration case by only comparing milliseconds if the
index entry has only millisecond precision.
The inverse may also occur; also compare only milliseconds if the
file timestamp has only millisecond precision.
Do the same also for microsecond resolution. On Windows, NTFS may
provide 100ns resolution and may be used by external programs writing
the index, but Java's WindowsFileAttributes may provide only
microseconds.
File timestamp precision in Java depends not only on the Java APIs
used by different JGit versions but may also change when running the
same Java code on different VMs. And of course the resolution may
vary among operating and file systems. Moreover, timestamp precision
in the index depends on the program that wrote the index. Canonical
git may use a different resolution, maybe even different between git
versions.

Remove an old work-around for core.autocrlf = input
The removed code was trying to avoid mistakenly reporting differences
when core.autocrlf was set to "input" but a file had already been
committed with CR-LF. It did that by running the blob from the cache
through a CRLF-to-LF filter because older JGit would also run the file
from the working tree through such a filter.
The real fix for this case was done in commit 60cf85a. Since then files
are not normalized if they have already been committed with CR-LF and
this old fix attempt from bug 372834 is no longer needed.
