c1ec732f	2016-03-14T12:02:00	Setup better defaults for OpenSSL ciphers This ensures that when using OpenSSL a safe default set of ciphers is selected. This is done so that the client communicates securely and we don't accidentally enable unsafe ciphers like RC4, or even worse some old export ciphers. Implements the first part of https://github.com/libgit2/libgit2/issues/3682

We already use the buffer to format the string, so this mostly makes that more direct.

a3aa5f4d	2013-09-11T12:45:20	Add simple global shutdown hooks Increasingly there are a number of components that want to do some cleanup at global shutdown time (at least if there are not going to be memory leaks). This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown. Right now, the maximum number of hooks is hardcoded, but since adding a hook is not a public API, it should be fine and I thought it was better to start off with really simple code.
e976b56d	2013-04-15T14:27:53	Add git__compare_and_swap and use it This removes the lock from the repository object and changes the internals to use the new atomic git__compare_and_swap to update the _odb, _config, _index, and _refdb variables in a threadsafe manner.

8cef828d	2012-08-18T22:11:49	Make the memory-window conrol structures global Up to now, the idea was that the user would do all the operations for one repository in the same thread. Thus we could have the memory-mapped window information thread-local and avoid any locking. This is not practical in a few environments, such as Apple's GCD which allocates threads arbitrarily or the .NET CLR, where the OS-level thread can change at any moment. Make the control structure global and protect it with a mutex so we don't depend on the thread currently executing the code.
