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...)

- Fix compile warning + broken fcn pointer from last commit.
...
- Address crashes in Tupdate() and recovery caused by mixing segments and page oriented recovery (add loadPageForOperation() call)

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

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
