cmd: Add a memory-search command
It is useful to be able to find hex values and strings in a memory range.
Add a command to support this.
cmd: Fix 'md' and add a memory-search command
At present 'md.q' is broken. This series provides a fix for this. It also
implements a new memory-search command called 'ms'. It allows searching
memory for hex and string data.

+ 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).
