Replace g_random and g_nondeterministic_random with functions deterministicRandom() and nondeterministicRandom() that return thread_local random number generators. Delete g_debug_random and trace_random. Allow only deterministicRandom() to be seeded, and require it to be seeded from each thread on which it is used.

Adjust all includes to be relative to the root.
...
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

Some code cleanup / renaming of things for clarity. Improved StringRef hex string output to omit a middle segment when there is an exceeded length limit.

Refactored how key/value memory is held in PrefixTree and VersionedBtree, eliminated many unnecessarily copies of large strings. PrefixTree tests pass but btree is still broken, just committing this because it's a large change set.

VersionedBTree now uses PrefixTree based pages (with bugs). This required significant changes to both classes because the interface and semantics for building, seeking in, and iterating through pages is very different from the previous trivial approach which was based on serialized vectors. PrefixTree node format rewritten to support optional values without increasing overhead for common node scenarios. PrefixTree::Cursor rewritten to reuse path prefix memory instead of allocating new memory on each movement which is then 'leaked' until destruction. PrefixTree::Cursor movement modified to work better with VersionedBTree::InternalCursor, which was also heavily modified. Added knobs related to key arrangement in PrefixTree nodes. Added StringRef::toHexString() as an alternative to printable() to make reading raw PrefixTree data easier. PrefixTree performance is temporarily worse with this update and VersionedBtree fails its unit test.

Added benchmark/test exploring different write patterns and how they might perform using a page delta based mutation buffer. Added more efficient cursor and PrefixTree::Node access methods for decoding specific members on demand.

Initial version of PrefixTree for use as Redwood's page format. Added Dave Scherer's CompactMap prototype and added PrefixTree testing to it along side CompactMap tests.
