This fixes in Stasis issue 22.
...
Replacement policies now track the pin count of each page that they interact with. This behavior used to live in bufferHash, and had never been ported to concurrentBufferManager.
For various reasons, the pin counts have to be updated atomically with the LRU state. This would be very difficult to do inside of concurrentBufferManager, which sometimes needs to add and remove pages to replacement policies without holding any other latches.

cleaned up arrayList. stasis_record_write no longer takes an LSN (it was ignoring it anyway). Added some missing calls to stasis_page_lsn_write (each time a page is written to, stasis_page_lsn_write should be called; this happens automatically for operations called via tupdate
