Up to now, BochsMemory::isMapped() always returned true in 32-bit protected
mode with a 4GB linear address space (as used by, e.g., eCos), even for
addresses greater than the configured memory size. This led to lots of
bogus memory dereferences in the (extended) tracing plugin.
This change (a follow-up to commit 5171645) additionally checks the return
value of getHostMemAddr(), and announces BX_RW (read/write access) instead
of BX_READ as the intended type of memory access. In the aforementioned
scenario, memory addresses greater than the memory size are now correctly
detected as "not mapped".

When a register in the extended trace was dereferenced and the value
was smaller than the memory pool size, but the address was not mapped
an assertion occured and the tracing plugin terminated the
simulator. Now the dereferenced memory address is checked for being
mapped and not being smaller than the memory pool.
