Thomas Sewell 7e9b8224ee Factor out bitfield proof text into Eisbach lib. 
There's a lot of proof text quoted into the source of the bitfield generator
(../seL4/tools/bitfield_gen.py). Optimising that requires even more complex
proof scripts. Instead of quoting them there, this introduces
lib/BitFieldProofsLib.thy which creates Eisbach methods for discharging some
relevant proof obligations. These can be tweaked without adjusting the
bitfield generator.

This approach could be taken a lot further to simplify the bitfield generator
further.
