another test that exposes a problem

Workaround for nested transactions not aborting correctly.
Needs to be replaced with a better version.

Reduce overhead of subtransactions

git-svn-id: file:///svn/tokudb@5674 c7de825b-a66e-492c-adef-691d508d4ae1

more the root_put_counter to the brt object.  this speeds up cursor operations.  we will address multiple brt handles later. addresses #1054

Replaced 'test_thread_stack.%' in rules with '$<', which refers to the first
prerequisite listed.

This fixes the nondeterministic nature of this test failing (for reasons
of being unable to find the binary).

git-svn-id: file:///svn/tokudb@5387 c7de825b-a66e-492c-adef-691d508d4ae1

Created function that peeks at both key and value at the same time
(to avoid repeated OMT calls).
This was worth 4-5% performance in scanscan --lwc --prelock --prelockflag


git-svn-id: file:///svn/tokudb@5386 c7de825b-a66e-492c-adef-691d508d4ae1

Speed up light weight cursors.
Instead of asking the brt to use 'copyout' (by passing key and/or val pointers)
we pass in NULLs to brt_cursor_get.
We then later use the peek_current functions to obtain pointers to the current
key and val of the cursor.

That was worth ~22% reduction in time for scanscan --lwc --prelock --prelockflag

Also, now copyout quits immediately if both key and val are NULL
This increased the (total) value of the patch to ~30% reduction  in time.
