- Replace HOBBY #ifdef with DEMO,

- Remove long integers so x86_64, where long is 8 bytes, is like i686
compile, where long is 4 bytes.
- Dont' handle xon/xoff on sys console in full duplex
- Add geom hash for DEMO emulator
- Add -mmacosx-version-min=10.4 option for DEMO emulator
- Add 1-line AMLC and 2-node PNC to DEMO emulator
