DFS block cache: fix lock issue and support parallel index loading
This change is a fix to http://git.eclipse.org/r/c/jgit/jgit/+/183562
that was reverted in http://git.eclipse.org/r/c/jgit/jgit/+/184978

on getting value from DfsBlockCache with region locking in place.

reverse index full initialization in DfsPackFile. Now bitmap index
and index could be read from storage in parallel in separate threads.

Unfortunately, the existing UploadPackTest didn't reveal this issue
although it provided the test case needed to do so: testV2LsRefsPeel.
This is because The UploadPackTest uses InMemoryRepository which
internally uses Dfs* implementations. The issue is only reproducible
when using the FileRepository.
It is a non-trivial task to refactor the UploadPackTest to work against
both InMemoryRepository and FileRepository and this change is not trying
to do that. This change creates a new test:
UploadPackLsRefsFileRepositoryTest and copies the necesssary code from
the UploadPackTest.
DFS block cache: allow multiple passes for blocks before eviction
Let certain pack extensions that are expensive to load from storage
(e.g. pack index, bitmap index) stay in DFS block cache longer than
others by overriding default cache count through DfsBlockCacheConfig
Don't change default behavior when cache override map is empty. Use int
cacheCount instead of boolean hot for Ref<T>
Find out which branches is 2 merged into:
After we calculated that master contains 2, we can mark 6 as TEMP_MARK
to avoid unwanted walks.
When we want to figure out if 2 is merge into the topic, the traversal
path would be [7, 6] instead of [7, 6, 5, 3, 2].
Test:
This change can significantly improve performance for tags.
On a copy of the Linux repository, the command 'git tag --contains
<commit>' had the following performance improvement:
The current version ignores tags, even though the tag is a type of
the ref.
Follow-up commits I'll fix it.

Enable compiler option --release
This ensures the compiler compiles against the public, supported and
documented API for a specific VM version (here 11) [1]. This also means
that
we don't need EE descriptors in Eclipse anymore in order to ensure that
only supported APIs of the selected Java version can be used.
According to [2] if option --release is used --source and --target
options can't be used.
While we are at it also add default value for all new jdt core options
added in Eclipse 4.21.
The reftable format is a block based format, but allows for variably
sized blocks. This obviously happens for reflog blocks (which are zlib
compressed), but is also accepted for index blocks: In the spec, this
is motivated as
To achieve constant O(1) disk seeks for lookups the index must be
a single level, which is permitted to exceed the file's
configured block size, but not the format's max block size of
15.99 MiB.
Hence, when parsing a block, one cannot be sure of its exact size:
after reading a default-size block (eg. 4kb), the block header may
state that the block is in fact larger.
Before, the code would mark the block as `truncated`, noting
// Its OK during sequential scan for an index block to have been
// partially read and be truncated in-memory. This happens when
// the index block is larger than the file's blockSize. Caller
// will break out of its scan loop once it sees the blockType.
This looks like either
* a remnant of never-implemented functionality. There is no reason to
ever sequentially scan an index block.
* alluding to sequential scan of the data blocks before the index
blocks (eg. scanning refs, which ends when we find the first ref index
block, and we can then ignore the index block).
This comment is followed by code that populates the
restartTbl/restartCnt fields relative to the (possibly truncated)
buffer. If the buffer is truncated, this essentially reads garbage,
leading to OOB array access when using the index block.
Fix this by dropping the truncated logic and issuing a second read if
the first read was short.
Add a test.
We have never observed this failure scenario at Google. We use 64kb
blocksize, which requires us to need fewer index entries. The reftable
spec mentions an Android repo of size 36M. With 64kb blocks, that's
just 562 index entries. Even with historical growth, we are long from
requiring an index whose size exceeds a single block.
When adding the analogous test for seeking refs, there was no failure.
This points to another possibility which is that the code tries to
avoid writing large index blocks for refs.

GitServlet: allow to override default error handlers
GitServlet delegates repository access over HTTP to the GitFilter
servlet.
GitServlet, in turn, can be extended by jgit consumers to provide custom
logic when handling such operations.
This is the case, for example, with Gerrit Code Review, which provides
custom behavior with a GitOverHttpServlet [1].
Among possible customizations, the ability of specifying a custom error
handler for UploadPack and ReceivePack was already introduced in
GitFilter by Idd3b87d6b and I9c708aa5a2, respectively.
However the `setUploadPackErrorHandler` and `setReceivePackErrorHandler`
methods were never added to the GitServlet.
Expose the `setUploadPackErrorHandler` and `setReceivePackErrorHandler`
methods to the GitServlet, so that consumers of the jgit library might
specify custom error handlers.
Sometimes it is useful to obtain metadata associated with an object
without the need to first download it locally. This is specially useful
when using partial clones.
This change implements the object-info capability that allows clients to
query the remote server for object metadata (currently only size). This
is a backport of the same capability that was recently added to the Git
project a2ba162cda (object-info: support for retrieving object info,
2021-04-20).

[gpg] Better GPG home directory determination
GPG can use customized directories instead of the standard ~/.gnupg or
%APPDATA%\gnupg directories:
* Environment variable GNUPGHOME can define the location.
* On Windows, a registry key may define the location (but this is
deprecated).
* Portable installations may use a directory defined via a file
"gpgconf.ctl".
* GPG programs may take a --homedir command-line argument, which
overrides anything.
Implement handling of environment variable GNUPGHOME. The other ways of
GPG to get its home directory are outside the reach of JGit. Provide a
system property "jgit.gpg.home" that the user can set in such cases.
Do tilde replacement for the system property and for GNUPGHOME.
Note that on VMS, the default directory would be ~/gnupg (without dot).
This is not accounted for, but a user on VMS could now use either the
system property or GNUPGHOME to direct JGit to the right directory.
