(* Tools to read data from Target or Own memory.
This is to deal in one place with all conversion of data from target format
to debugger format.
A typical read would involve the following steps:
The code calls MemoryManager with an Address, a Size and a space for the data.
If the data needs to be extended (SizeOf(data) > TargetSize), then
MemConvertor is called to decide where in rovided space the read data should
initially be stored.
Then the data is read using MemReader.
And finally MemConvertor is given a chance to extend or convert the data.
