git-svn-id: file:///svn/tokudb@2877 c7de825b-a66e-492c-adef-691d508d4ae1

Reordered escalation.
First escalate writes, and only if that succeeds, we escalate the reads.
Now, if we fail during the reads we are still consistent, whereas before
we would need to panic.

git-svn-id: file:///svn/tokudb@2876 c7de825b-a66e-492c-adef-691d508d4ae1

Implemented testing if escalating a range from borderwrite is trivial.

git-svn-id: file:///svn/tokudb@2875 c7de825b-a66e-492c-adef-691d508d4ae1

Started coding lock escalation.
Have several function stubs that need to be implemented.

Deal with the multithreaded cursor DBT memory allocaiton problem.  Addresses #538.  (I'm going to write a few more tests before calling it fixed.)

create (but not yet implement) functions for lock escalation

git-svn-id: file:///svn/tokudb@2836 c7de825b-a66e-492c-adef-691d508d4ae1

Segrate rollback and recover functions.   Write a brt-level test for the cursor static variable problem.  Addresses #536, #538.

git-svn-id: file:///svn/tokudb@2829 c7de825b-a66e-492c-adef-691d508d4ae1

write iterator for linear range tree

git-svn-id: file:///svn/tokudb@2826 c7de825b-a66e-492c-adef-691d508d4ae1

Uses range iterator (of range trees) to simplify code in lock tree.

This allowed us to deleting 'emergency' version of a function that was not well tested.
