Fixed numerous bugs in allocationPolicy.c and alloc.c

allocationPolicy.c was not handling deallocations correctly
Tdealloc() was not calling interpretRid() on its input before passing it into the allocationPolicy
Added locking support for TallocFromPage()

Force in-flight page file writes to disk before truncating. (Needed if

O_DIRECT isn't in use.)
Changed diagnostic messages to go to stderr.

Now, you can set pageFile_isDurable=0 to disable forcing data to the
...
page file.
Also, -DPAGE_FILE_O_DIRECT switches the page file from using a normal
file handle and fdatasync to use O_DIRECT with no fdatasync.

Minor cleanup, added ability to calculate the global average number of

buckets traversed per find(). Added a warning for code that actually
relies upon PBL's way of interpreting insert.

Test is more stringent now; it runs in roughly the same amount of time

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
...
of pages, so it doesn't suggest ones that aren't already in the buffer pool unless it has to.

Removed the fixed page initialization operations, which weren't being used, and were a slow hack anyway. There is now a more-general (and efficient)

The "WARNING: Tdeinit() is aborting transaction %d" runtime message now
...
lists the xid of the transaction it's aborting instead of "-1".
TisActiveTransaction(xid) now returns 0 for INVALID_XID. Before the
output was undefined.

Fixed segmentation fault when a CLR with a NULLRID is encountered. I

don't understand why this bug wasn't triggered by linearHashNTA or
linkedListNTA, but is triggered by the new region implementation.
