Log Message:
-----------
add PMC_HEADER_PREAMBLE section to PMC grammar

This allows declarations to be inserted before all PMC supporting definitions,
allowing changes in behaviour. An example of where this might be desirable is
user-defined typedefs in attributes.

implement 3 levels of pointer-type objects

Ptr - baseline pointerish function. big nastygram in description to fight feature creep.
PtrBuf - can also keeps track of size
PtrObj - can also clone and manage memory

Log Message:
-----------
move bit and nybble handling to unsigned

bits are unsigned by definition (otherwise they'd just be signed nothingness)
nybbles are hard to do signed (hardware and compiler support are uncommon) and not really all that useful.
