Much like IP_RECVTTL does for TTL. This allows to implement a

- Consistently refer to rmlocks as "read-mostly locks".
- Relate rmlocks to rwlocks rather than sx locks since they are closer to
rwlocks.
- Add a separate paragraph on sleepable read-mostly locks contrasting them
with "normal" read-mostly locks.
- The flag passed to rm_init_flags() to enable recursion for readers is
RM_RECURSE, not LO_RECURSABLE.
- Fix the description for RM_RECURSE (it allows readers to recurse, not
writers).
- Explicitly note that rm_try_rlock() honors RM_RECURSE.
- Fix some minor grammar nits.

List of these flags can be modified with CAM_DEBUG_COMPILE kernel option.
CAMDEBUG kernel option still enables all possible debug, if not overriden.
Additional 50KB of kernel size is a good price for the ability to debug
problems without rebuilding the kernel. In case where size is important,
debugging can be compiled out by setting CAM_DEBUG_COMPILE option to 0.
Add source of documentation for this driver.
