git: improve performance working with git changesets
GitRepository._repo instantiates a new dulwich.repo.Repo on every usage,
rather than once at initialization time of GitRepository. As this involves a
lot of filesystem access, this is a costly operation.
Instead, let GitRepository.__init__ instantiate a dulwich.repo.Repo once,
and let GitRepository._repo just return it.
This improves performance significantly.
On test_graphmod_git, performance improves from 6.29 seconds median to 3.06
seconds median.
[Thomas De Schampheleire: extend improvement to _all_ usage of
GitRepository._repo instead of only some. To limit the delta, retain the
_repo property but simply return self.repo.]

==================
Repository locking
==================
Kallithea has a *repository locking* feature, disabled by default. When
enabled, every initial clone and every pull gives users (with write permission)
the exclusive right to do a push.
When repository locking is enabled, repositories get a ``locked`` flag.
The hg/git commands ``hg/git clone``, ``hg/git pull``,
and ``hg/git push`` influence this state:
- A ``clone`` or ``pull`` action locks the target repository
if the user has write/admin permissions on this repository.
- Kallithea will remember the user who locked the repository so only this
specific user can unlock the repo by performing a ``push``
command.
- Every other command on a locked repository from this user and every command
from any other user will result in an HTTP return code 423 (Locked).
Additionally, the HTTP error will mention the user that locked the repository
(e.g., “repository <repo> locked by user <user>”).
Each repository can be manually unlocked by an administrator from the
repository settings menu.
