[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.

DFS block cache: Refactor to enable parallel index loading
With this change bitmap index creation is not blocked on index and
reverse index full initialization in DfsPackFile. Now bitmap index and index could be
read from storage in parallel in separate threads.
Update PackBitmapIndexV1 constructor to get packIndex and reverseIndex
suppliers instead of actual objects. Inner class IdxPositionBitmap was added to initialize pack objects after bitmap
index is fully read from storage. Update DfsPackFile and PackBitmapIndex
accordingly.

[sshd] Distinguish key type and signature algorithm for host key
Since the introduction of the rsa-sha2-512 and rsa-sha2-256 signature
types, the key type for RSA is no longer automatically the signature
algorithm. We re-order the list for the host key proposal such that
keys we already have are preferred; this minimizes warnings about new
host keys. When doing so, put all of rsa-sha2-512, rsa-sha2-256, and
ssh-rsa at the front, in that order, not just ssh-rsa.
This ensures that we do prefer RSA keys if we already have an RSA host
key, but at the same time we still prefer the stronger signature
algorithms over the weaker and deprecated SHA1-based ssh-rsa signature.
It also helps avoid a bug found in some Github versions where the Github
SSH server uses a rsa-sha2-512 signature even though ssh-rsa was
negotiated.[1]

[sshd] Implement SSH config KexAlgorithms
Make the used KEX algorithms configurable via the ssh config. Also
implement adding algorithms not in the default set: since sshd 2.6.0
deprecated SHA1-based algorithms, it is possible that the default set
has not all available algorithms, so adding algorithms makes sense.
This enables users who have to use a git server that only supports
old SHA1-based key exchange methods to enable those methods in the
ssh config:
KexAlgorithms +diffie-hellman-group1-sha1
There are two more SHA1 algorithms that are not enabled by default:
diffie-hellman-group14-sha1 and diffie-hellman-group-exchange-sha1.
KeyAlgorithms accepts a comma-separated list of algorithm names.
Since adding algorithms is now supported, adapt the handling of
signature algorithms, too. Make sure that definitions for the KEX
exchange signature (HostKeyAlgorithms) don't conflict with the
definition for signatures for pubkey auth (PubkeyAcceptedAlgorithms).
HostKeyAlgorithms updates the signature factories set on the session
to include the default factories plus any that might have been added
via the SSH config. Move the handling of PubkeyAcceptedAlgorithms
from the client to the JGitPubkeyAuthentication, where it can be done
only if pubkey auth is attempted at all and where it can store its
adapted list of factories locally.

Retry loose object read upon "Stale file handle" exception
When reading loose objects over NFS it is possible that the OS syscall
would fail with ESTALE errors: This happens when the open file
descriptor no longer refers to a valid file.
Notoriously it is possible to hit this scenario when git data is shared
among multiple clients, for example by multiple gerrit instances in HA.
If one of the two clients performs a GC operation that would cause the
packing and then the pruning of loose objects, the other client might
still hold a reference to those objects, which would cause an exception
to bubble up the stack.
The Linux NFS FAQ[1] (at point A.10), suggests that the proper way to
handle such ESTALE scenarios is to:
"[...] close the file or directory where the error occurred, and reopen
it so the NFS client can resolve the pathname again and retrieve the new
file handle."
In case of a stale file handle exception, we now attempt to read the
loose object again (up to 5 times), until we either succeed or encounter
a FileNotFoundException, in which case the search can continue to
Packfiles and alternates.
The limit of 5 provides an arbitrary upper bounds that is consistent to
the one chosen when handling stale file handles for packed-refs
files (see [2] for context).

Teach independent negotiation (no pack file) using an option "wait-for-done"
From Git commit 9c1e657a8f:
Currently, the packfile negotiation step within a Git fetch cannot be
done independent of sending the packfile, even though there is at
least one application wherein this is useful - push negotiation.
Therefore, make it possible for this negotiation step to be done
independently.
This feature is for protocol v2 only.
In the protocol, the main hindrance towards independent negotiation is
that the server can unilaterally decide to send the packfile. This is
solved by a "wait-for-done" argument: the server will then wait for
the client to say "done". In practice, the client will never say it;
instead it will cease requests once it is satisfied.
Advertising the server capability option "wait-for-done" is behind the
transport config: uploadpack.advertisewaitfordone, which by default is
false.
