* Block allocation is now first-fit.
* There is a better test for the block allocator.
* brt_stat64 returns data in a struct instead of a bunch of arguments.
* Nodes are set clean after serialization.

Added option to easily toggle implicit promotion on query
Disabled for now because of tickets [t:1903] [t:1906]
git-svn-id: file:///svn/toku/tokudb@13679 c7de825b-a66e-492c-adef-691d508d4ae1
Fix bug where assert was hit when transactions are off.
Cleaned up some code.
git-svn-id: file:///svn/toku/tokudb@13625 c7de825b-a66e-492c-adef-691d508d4ae1
Cursors take a copy of oldest living xid upon creation, which they use for implicit promotion

When a new brt is open, it takes over responsibilities of all existing zombie brts, and closes them.
When a brt closes, if other brts exist, it passes off responsibilities and closes immediately. It only becomes a zombie if no other brts exist.
(Everything above is in context of a single header).
git-svn-id: file:///svn/toku/tokudb@11533 c7de825b-a66e-492c-adef-691d508d4ae1
Remove transactions' need to count references to cachefiles (they already have references to brts)
Errors in rolling back certain functions were ignored (r = blah; return something_else);
They are now reported, so diskfull had to be updated to expect ENOSPC under certain circumstances.

We clear it when the transaction closes (this means we cannot change it when it is already set till that transaction finishes).
This fixes a crash in windows in root_fifo_2.tdb
git-svn-id: file:///svn/toku/tokudb@11365 c7de825b-a66e-492c-adef-691d508d4ae1
version now comes before 'size' in header
Some cleanup/defined new error codes instead of '-1'

If descriptor contents stay the same but version goes up, record new version (instead of ignore it).
git-svn-id: file:///svn/toku/tokudb@11263 c7de825b-a66e-492c-adef-691d508d4ae1
Serialize descriptor with each brtnode (leaf and nonleaf)
Deserialize descriptor with each brtnode (to be thrown away).
Don't malloc+memdup the descriptor for brtnodes, since that would waste time.
git-svn-id: file:///svn/toku/tokudb@11200 c7de825b-a66e-492c-adef-691d508d4ae1
Added versioning to descriptor.
Changing a descriptor REQUIRES the version to increase.
Version 0 is reserved for a non-descriptor db. (cannot be set).
Not yet added to brtnodes.
Still possible to change descriptor with an open brt (which would not be upgraded).
git-svn-id: file:///svn/toku/tokudb@11198 c7de825b-a66e-492c-adef-691d508d4ae1
Will aid in having multiple DB handles to a single brt, which is needed to kill root fifo
git-svn-id: file:///svn/toku/tokudb@11157 c7de825b-a66e-492c-adef-691d508d4ae1
Several fixes are included, particulary db remove after db truncate (with descriptor) does not crash anymore.
