Summary: UMR detector

Initial Comment:
We encountered a problem the other day with "Namake's
Bridgedrome". It was caused by an UMR in the MSX
program itself.

That's why I thought it might be nice to have an UMR
detector built in the openMSX debugger.

openMSX could simply keep track of which bytes in RAM
were written to and which not. In case a byte gets read
which was not written to before, openMSX can give a
warning, or log it or something.
Why find out UMR's manually while openMSX can perfectly
automate it for you?

An extra could be a check if the PC gets in
uninitialized memory.

Implemented. Use the new umr_callback setting: set it to a
TCL proc and it will be called every time an UMR is detected
(for devices that use CheckedRam only!).
