The main motivation for this change is that only Loris supports multithreading, and Loris supports dynamic thread allocation, so the number of supported threads can be implemented as a bit flag (i.e., either 1 or "at least as many as VFS has"). The ABI break obviates the need to support file system versioning at this time, and several other aspects are better implemented as flags as well. Other changes: - replace peek/bpeek test upon mount with FS flag as well; - mark libsffs as 64-bit file size capable; - remove old (3.2.1) getdents support.
