UploadPack: Implement deepen-not for protocol v2
This allows clients to use the --shallow-exclude parameter (producing a
"deepen-not <ref>" line when communicating with the server) in their fetch
commands when fetching against a JGit server using protocol v2.
Note that the implementation in this commit is somewhat inefficient, as
described in the TODO comment in DepthGenerator.

Throw error when deepen-since excludes all commits
In C Git, when a client fetches with "git fetch --shallow-since=<date>
origin <ref>", and all commits reachable from <ref> are older than
<date>, the server dies with a message "no commits selected for shallow
requests". That is, (1) the --shallow-since filter applies to the commit
pointed to by the ref itself, and (2) there is a check that at least one
commit is not filtered out. (The pack-protocol.txt documentation does
not describe this, but the C implementation does this.)
The implementation in commit 1bb430dc21 ("UploadPack: support
deepen-since in protocol v2", 2018-09-27) does neither (1) nor (2), so
do both of these.

Make PrePushHook properly terminate ref lines
All of the input lines passed to pre-push hook scripts must be properly
terminated by '\n', so that normal shell scripts like the git-supplied
pre-push.sample work properly, even when pushing just a single branch.

CheckoutCommand: force flag now allows overwrite
Before this commit, a force checkout would fail if there
were any conflicting files. After this commit, a force
checkout will overwrite the conflicting files, as expected.
Making this work required fixing a bug in DirCacheCheckout.
Before this commit, when DirCacheCheckout had
failOnConflict=false, it would delete all conflicting files
from the working copy and just leave them missing. After
this commit, DirCacheCheckout overwrites conflicting files
with the merge tree.
This change in DirCacheCheckout causes "reset --hard" and
"revert --abort" to behave as expected (previously they
would simply delete conflicting files, now they will be
overwritten from the merge tree).

UploadPack: Return correct peer user agent on v2 requests
UploadPack.getPeerUserAgent() doesn't produce the expected results for
protocol v2 requests. In v2, the agent reported in the request (in an
"agent=" line) is not in the clientCapabilities but in a field on its
own. This makes getPeerUserAgent default to the transport user agent.
Making "agent" a shared property between protocol v0/v1 and v2 fixes the
problem, simplifies the function and harmonizes the implementation
between protocol versions.
In a follow up commit the "agent" will be identified on parsing time,
instead of taking it from the client capabilities.

ssh: Prefer algorithms of the known host keys
JSch prefers ssh-rsa key type. When the remote server supports ssh-rsa

This caused an unexpected UnknownHostKey error.
