df1c7a9379 Addresses #903 
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

b5d3b778d6 Addresses #903 
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.

Also for 512 blocks it runs at 741MB/s,

It looks like the cachetable is fast enough.

Fixes #1037.
