At present this function assumes that a size of 4 refers to a ulong. This
is true on 32-bit machines but not commonly on 64-bit machines.
This means that the 'l' specify does not work correctly with setexpr.
Add an explicit case for 32-bit values so that 64-bit machines can still
use the 'l' specifier. On 32-bit machines, 64-bit is still not supported.
This corrects the operation of the default size (which is 4 for setexpr),
so update the tests accordingly.
The original code for reading from memory was included in 47ab5ad1457
("cmd_setexpr: allow memory addresses in expressions") but I am not adding
a Fixes: tag since that code was not written with 64-bit machines in mind.

This command currently has no tests. Add some for basic assignment and the
integer operations.
Note that the default size for setexpr is ulong, which varies depending on
the build machine. So for sandbox on a 64-bit host, this means that the
default size is 64 bits.

Add various fixes and improvements to this command that were missed in
the original version. Unfortunately I forgot to send v2.
- Fix Kconfig name
- Use a separate variable for the remaining search length
- Correct a minor bug
- Move into a separate test suite
- Add -q flag to the 'quiet' test to test operation when console is enabled
- Enable the feature for sandbox

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.
