common/buffer: replace RWLock with spinlocks

This decreases buffer::raw size by about 100 bytes (since RWLock occupies
104 bytes and simple_spinlock_t just 4) and also significantly decreases
time wasted by locking and unlocking, possibly reducing context switches too.
Particularly visible when using small blocksizes.
