- Replace instances of error/printf + exit(1) with nyx_abort(), except
for one instance where we don't give any useful error and a plain
assert() seems more appropriate
- Remove [Qemu-Nyx] and Error: in arguments to nyx_error()
Tried to minimize actual code modifcations but we got
- several comments/printf messages edited to meet line limits
- occasionally switch some lines to put declarations or printfs in blocks
- couple more places marked TODO or FIXME to avoid non-trivial changes
- fixed PAGE_SIZE define in helpers.h to avoid redeclaration warning
- remove several chunks of dead or commented code
