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.

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.
