Hypercall failed to handle the default case where 0 < ret_value < 4096.
The handler keeps looping over num_addresses, returning a too large
overall file size to the guest.
For a 4 byte test file, hget_bulk() would fetch + write 960 bytes.
Also moved struct definition to header + set __attribute__((packed)).
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

This introduces generic printf wrappers to replace the various
instances of debug_printf, fprintf, QEMU_PR_PRINTF etc.
Several more hardcoded printf() are still present and should probably be
replaced with nyx_debug_p().
Decide which crash notifier (32bit or 64bit) to inject, based on the
current memory mode instead of the current CPU mode. Otherwise, in the
case of a 32bit loader running on a 64bit operating system, the wrong
notifier code will be injected.
