branches/zip: Implement wrappers for all operations on the buffer pool mutex. 

buf_pool->mutex: Rename to buf_pool_mutex, so that the wrappers will have
to be used when changes are merged from other source trees.

buf_pool->zip_mutex: Rename to buf_pool_zip_mutex.

buf_pool_mutex_own(), buf_pool_mutex_enter(), buf_pool_mutex_exit():
Wrappers for buf_pool_mutex.
