New "default" buffer manager that aims to replace the current one, but

Added partial implementation of range tracking for pinning arbitrary

regions. Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n

a place in memory where the pincount changes.

non_blocking is closer to working (it now flushes writes out in the background). This required some api changes. It still passes unit tests, but it's losing data on close()...

Fixed initialization bugs on pendingCommits and syncLogCount. Group commit used to hang with 100% CPU if a signal interrputed it. Now it ignores the signal. (Don't know why it's receiving a singal, so it warns when this happens...)

Now, you can set pageFile_isDurable=0 to disable forcing data to the

Also, -DPAGE_FILE_O_DIRECT switches the page file from using a normal

Talloc() now reuses space when possible. It still needs to call slottedCompact() intelligentally. Also, allocationPolicy should support an extra tier
