BasePackConnection: Check for expected length of ref advertisement
When a server sends a ref advertisement using protocol v2 it contains
lines other than ref names and sha1s. Attempting to get the sha1 out
of such a line using the substring method can result in a SIOOB error
when it doesn't actually contain the sha1 and ref name.
Add a check that the line is of the expected length, and subsequently
that the extracted object id is valid, and if not throw an exception.

TransferConfig: Make constructors public
UploadPack has a setTransferConfig method which allows to set the
transfer config, however since the constructors of TransferConfig
have the default package visibility it is not possible for any
application using UploadPack, for example Gerrit, to actually set
a transfer config.
Make the constructors public. This is consistent with the public
constructors for example on PackConfig.

Fix DescribeCommand with multiple match options
when multiple match options are given in git describe the result must
not depend on the order of the match options. JGit wrongly picked the
first match using the match options in the order they were defined. Fix
this by concatenating the streams of matching tags for all match options
and then choosing the first match on the concatenated stream sorted in
tie break order.

Fix git-describe tie-breakers
Correct behaviour as git 1.7.1.1 is to resolve tie-breakers to choose

ssh: Prefer algorithms of the known host keys
JSch prefers ssh-rsa key type. When the remote server supports ssh-rsa
key type then this key type will be used even if the known_hosts file
contains a host key for that host, but with different key type.
This caused an unexpected UnknownHostKey error.
To fix the issue first scan the known_hosts, the HostKeyRepository in
JSch API, for any already existing host keys for the target host and
modify the default session settings to prefer their algorithms. However,
do this only if there is no HostKeyAlgorithms setting active.

SubmoduleValidator: Permit missing path or url
A .gitmodules file can include a submodule without a path to configure
the URL for a submodule that is only present on other branches.
A .gitmodules file can include a submodule with no URL and no path to
reserve the name for a submodule that existed in earlier history but
is not available from any URL any more.
"git fsck" permits both of these cases. Permit them in JGit as well
(instead of throwing NullPointerException).

Do it in the ObjectChecker stage. Check in the tree objects if they
point to a .gitmodules file and report the tree id and the .gitmodules
blob id.
This can be used later to check if the file is in the root of the
project and if the contents are good.

of filenames that vary in case.
