fat-rwlock: New big but fast synchronization primitive.

This implements a reader-writer lock that uses a lot of memory (128 to 192
bytes per thread that takes the lock) but avoids cache line bouncing when
taking the read side.  Thus, a fat_rwlock is a good choice for rwlocks
taken frequently by readers.
