memory: Have 'info mtree' remove duplicated Address Space information
Per Peter Maydell [*]:
'info mtree' monitor command was designed on the assumption that
there's really only one or two interesting address spaces, and
with more recent developments that's just not the case any more.
Similarly about how the FlatView are sorted using a GHashTable,
sort the AddressSpace objects to remove the duplications (AS
using the same root MemoryRegion).
This drastically reduces the output of 'info mtree' on some boards.
Before:
$ (echo info mtree; echo q) \
| qemu-system-aarch64 -S -monitor stdio -M raspi3b \
| wc -l
423
After:
$ (echo info mtree; echo q) \
| qemu-system-aarch64 -S -monitor stdio -M raspi3b \
| wc -l
106
