sshd: try all configured signature algorithms for a key
For RSA keys, there may be several configured signature algorithms:
rsa-sha2-512, rsa-sha2-256, and ssh-rsa. Upstream sshd has bug
SSHD-1105 [1] and always and unconditionally uses only the first
configured algorithm. With the default order, this means that it cannot
connect to a server that knows only ssh-rsa, like for instance Apache
MINA sshd servers older than 2.6.0.
This affects for instance bitbucket.org or also AWS Code Commit.
Re-introduce our own pubkey authenticator that fixes this.
Note that a server may impose a penalty (back-off delay) for subsequent
authentication attempts with signature algorithms unknown to the server.
In such cases, users can re-order the signature algorithm list via the
PubkeyAcceptedAlgorithms (formerly PubkeyAcceptedKeyTypes) ssh config.

OpenSSH has changed some things in ssh config files. Update our parser
to implement some of these changes:
* ignore trailing comments on a line
* rename PubkeyAcceptedKeyTypes to PubkeyAcceptedAlgorithms
Note that for the rename, openSSH still accepts both names. We do the
same, translating names whenever we get or set values.

Apache MINA sshd 2.6.0 appears to use only the first appropriate
public key signature algorithm for a particular key. See [1]. For
RSA keys, that is rsa-sha2-512. This breaks authentication at servers
that only know the older (and deprecated) ssh-rsa algorithm.
With PubkeyAcceptedAlgorithms, users can re-order algorithms in
the ssh config file per host, if needed. Setting
PubkeyAcceptedAlgorithms ^ssh-rsa
will put "ssh-rsa" at the front of the list of algorithms, and then
authentication at such servers with RSA keys works again.

In cases where we need to determine if a given commit is merged
into many refs, using isMergedInto(base, tip) for each ref would
cause multiple unwanted walks.
getMergedInto() marks the unreachable commits as uninteresting
which would then avoid walking that same path again.
Using the same api, also introduce isMergedIntoAny() and
isMergedIntoAll()

There are two code paths for detecting renames: one on tree diffs
(using DiffFormatter#scan) and the other on single file diffs (using
DiffFormatter#format). The latter skips binary and large files
for rename detection - check [1], but the former doesn't.
This change skips content rename detection for the tree diffs case for
large files. This is essential to avoid expensive computations while
reading the file, especially for callers who don't want to pay that
cost. Content renames are those which involve files with slightly
modified content. Exact renames will still be identified.
The default threshold for file sizes is reused from
PackConfig.DEFAULT_BIG_FILE_THRESHOLD: 50 MB.

HTTP cookies: do tilde expansion on http.cookieFile
Git config http.cookieFile must have ~ expansion, compare [1].
It also should be an absolute path. While a relative path is allowed,
C git just passes the value on to libcurl, so it'll be relative to the
current working directory and thus not work in all directories.
Log a warning if the path is relative.
(Alternatives would be to throw an exception, or to resolve the path
relative to the .git directory, or relative to the working tree root,
or relative to the config file it occurs in. But C git does not seem
to do either.)

Add new constructors to PackFile to improve a common use case where
callers know the directory, id, and extension, but previously needed to
construct a valid file name (with prefix, '.', etc) to create a
PackFile. Most callers can use the variant that has id as an ObjectId,
but provide an id as String variant too.

Restore preserved packs during missing object seeks
Provide a recovery path for objects being referenced during the pack
pruning race. Due to the pack pruning race, it is possible for objects
to become referenced after a pack has been deemed safe to prune, but
before it actually gets pruned. If this happened previously, the newly
referenced objects would be missing and potentially result in a
corrupted ref.
Add the ability to recover from this situation when an object is missing
but happens to still be available in a pack in the "preserved"
directory. This is likely only useful when used in conjunction with the
--preserve-old-packs GC option, which prunes packs by hard-linking to
the preserved directory. If an object is missing and found in a pack in
the preserved directory, immediately recover that pack and its
associated files (idx, bitmaps...) by moving them back to the original
pack directory, and then retry the operation that would have failed due
to the missing object. This retry can now succeed and the repository
may avoid corruption. This approach should drastically reduce the
chance of a corrupt repository during pack pruning at very little extra
cost. This extra cost should only be incurred when objects are missing
and a failure would normally occur.

PackDirectory: Use PackFile to ensure we find preserved packs
Update scanPacksImpl and listPackDirectory (renamed to
getPackFilesByExtById) to use the new PackFile functionality to
validate file names and complete pack file sets (.pack, .idx, etc).
Most importantly, this allows a later change to rely on scanPacks() to
complete a packList that contains packs with the 'old-' prefix in their
extension.
This also eliminates duplication of logic for how to identify and
construct pack files.
