Summary: Fix OID packing/unpacking bottleneck

Initial Comment:
The OID-packing functions in ZODB/utils.py are a
noticeably performance bottleneck.  This patch rewrites
them in C to speed things up.

Details:
  * adds ZODB/oidutils.h to define C macros for OID
packing/unpacking
  * adds ZODB/oidutils.c (aka the ZODB.oidutils
extension module) to
    expose Python wrappers for those C macros
  * eliminate most of the code in ZODB/utils.h, and
replace it with
    imports from ZODB.oidutils
