cooker, seitan: Now with 100% more gluten
Pseudorandom changes and progress around cooker and seitan:
- cooker:
- rename matching functions, split match.c
- fix up SELECT semantics
- add some form of handling for all syscalls in the example
(some stubs)
- OP_CMP for all basic and compound types except for flags
- link jumps to next block and next match
- completed implementation of tags
- gluten write
- filter clean-ups, write filters (probably not working)
- seitan:
- load gluten and source instructions and data from there
