Code

Move nbtree preprocessing into new .c file.

Browse Source 
Quite a bit of code within nbtutils.c is only called during nbtree
preprocessing.  Move that code into a new .c file, nbtpreprocesskeys.c.
Also reorder some of the functions within the new file for clarity.

This commit has no functional impact.  It is strictly mechanical.
