Current
============
* option: whether to search in readonly regions

* optional float rounding method, eg floor(), ceil(), round(), rint(), etc?
* speedhack
* bytearray flag check (truncval_to_flags, checkmatches, update command for bytearray&string)

Future
======
* use PT_IO on freebsd, instead of PT_READ/WRITE_D
* in target_memory_info_array.c, need check return value of allocate_enough_to_reach everywhere
* search for values in files? (eg saved state)
* macro support
* automatically support zero and one based values.
* dont read the whole region at a time, read max 8M or something.
