HAMMER 35/many: Stabilization pass, cleanups
* Fix a buffer load race which could result in an assertion or panic
related to a referenced HAMMER buffer with a NULL bp. The problem was
that the loading flag must be used when releasing the buffer as well
as when acquiring the buffer. Change the loading flag to a loading
count.
* Do not lose flush requests. The flush request now stays flagged until
the buffer is able to be flushed.
* Fix stale blockmap offsets cached in hammer_buffer. Clear the cached
offset when freeing a big block from the blockmap. NOTE: We do not yet
try to index buffers based on the blockmap offset but we should.
* Remove the old write ordering code in preparation for redoing the algorithm.
* General code cleanups.
