Replace cache_inode_file_holds_state with cache_inode_is_pinned

By checking if file is pinned, cache_inode_close doesn't need to
poke into SAL internals. Also avoids checking if state is present
without holding state_lock.

Added CACHE_INODE_FLAG_NOT_PINNED. This informs cache_inode_close
that the file is known to be unpinned, and therefore
cache_inode_close will not call cache_inode_is_pinned. This avoids
a lru mutex deadlock.

Also, add/modify some debug log messages.

Make abstrat_atomic consistent

Unadorned atomic_ operations now return the value after performing the
operation on all supported versions of GCC.

A new family of functions, atomic_post returns the value before
performing the operation (analogous to the post-increment/decrement
operators).

Convert NSM and NLM Client to new HashTable_GetLatch

Converting NSM Client and NLM Client to use new HashTable_GetLatch
allows atomic creation of those object types. Also, the refcounts
are converted to atomic int32_t so that mutex doesn't need to be
held for refcount operations.

Convert state owners to use new HashTable_GetLatch

Using HashTable_GetLatch allows state owners to be created
without worry of race. The so_refcount is also converted to
an atomic uint32_t to allow refcounting without grabbing
so_mutex.

All state owners are hashed using the state_owner_t structure
as the key as well as the data. The key fields are all available
within the state_owner_t structure so the hash may use them
for key evaluation. This reduces memory use.

There is now a generic get_state_owner which will determine
which hash table to use based on so_type in the key. Callers
may indicate if they care if the owner is found or not, if they
don't care, a new owner is not created if not found.

With --enable-debug-memleaks, keep list of all state owners and stateids

To help track down memory leaks in SAL, keep a list of all state owners
and stateids. When clientid reaper thread has removed all clientids,
print the contents of the lists (which should be empty) to expose any
leaks.
