add thread synchronization logic to ensure that only one thread is performing writeback at a time. This fixes weird I/O interleavings on some machines

IMPORTANT API CHANGE: stasis_dirty_page_table_flush_range() no longer force writes to disk. You now need to call forcePageRange() after flush page range returns.
...
This commit should significantly improve sequential write thoughput.
I found a segfault bug this morning, but cannot reproduce. Could be a heisenbug, or could have been a hardware fault (gojira repeatedly kernel paniced, then both problems went away...)

Remove LRU-ordered writeback. Instead, writeback pages sequentially once some fraction of the page file is dirty. Also. further simplifies writeback code.

dirty page table flush was pinning pages, then asserting they were not pinned; updated page writeback api to allow correct usage

Add getCachedPage() call. This allows dirtyPageTable to write back pages with out accidentally reading them back in from disk with loadPage(). This should improve performance and allow loadPageOfType() to be used safely.

Added support for segment based recovery. For now, Stasis doesn't support hybrid recovery, so mixing page deallocation and segments will make recovery corrupt data / segfault.

Move page type to Page_s struct. This breaks indirect.c (which is poorly thought out, and will be removed shortly), and was the next step on the road to segment-based recovery
