Add 'serial' and 'parallel' keywords to the grammar so that one can 

say whether parts support these programming modes or not.  Possible
values for 'serial' are 'yes' or 'no'.  Possible values for 'parallel'
are 'yes', 'no', or 'pseudo'.  Add a bit mask of flags to the AVRPART
structure to capture these settings.  Use these within
stk500_initialize() to set the device parameters correctly.

Defaults for 'serial' and 'parallel' are 'yes' unless specified
otherwise.
