FEXServerClient: Workaround sun_path 108 byte limit

We really don't want to do this, but in the case that the AF_UNIX path is longer than the 108-byte limit that sun_path provides we don't really have a choice. The alternative choice would be to switch /entirely/ away from AF_UNIX and instead use pipes. We need a bandage fix for now, so throw the socket in to a temp folder if the path is too long.

- * - Exactly one CodeBuffer is now designated as "active", which means data can be appended to it
- * - Lossy modifications to the active CodeBuffer will not invalidate any data in use by other threads (which is what enables save CodeBuffer sharing across threads)
- * - Instead, such lossy modifications trigger a new "version" of the data in the modifying thread. Old versions of the CodeBuffer persist as read-only data for use by the other threads.
- * - The other threads can update their version of the CodeBuffer. This will decrease the reference count and eventually trigger deallocation of the old version
