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.
