Added function to handle code that allocates data without first consulting the allocationPolicy

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()

appropriate.

Added logWriter_isDurable. If = 0, then the log will never be forced.

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

becase pageFile.c is no longer using O_DIRECT.

Needed to protect a linked list with a mutex. It's suprising that this hasn't come up before.

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)
...
implementation in alloc.c
