Memory-search command
This allows searching through a region of memory looking for hex
data (byte, 16-bit word, 32-bit long, also 64-bit on machines that
support it). It is also possible to search for a string. The
command accepts a memory range and a list of values to search for.
The values need to appear in memory in the same order they are given
in the command. At most 10 matches can be returned at a time, but
pressing return will show the next 10 matches. Environment variables
are set for use with scripting (memmatches, memaddr, mempos).
