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).

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.
