- printf that looks like debug/status info or disabled by macro/comments
mostly turned to corresponding nyx_debug()
- printf followed by exit/abort/assert turned to nyx_error(),
or nyx_abort() if the error is unlikely to need backtrace/gdb
- non-fatal error/warning messages turned to nyx_warn()
- few hardcoded printf remain, e.g. hexdump and debug helpers
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
