* Improve vmmap on coredump files
With this commit we now recognize coredumps better and also finally have
a simple test for vmmap commands on:
- a running binary
- on a loaded coredump file with loaded binary
- on a loaded coredump file without a loaded binary
We also stop saving vmmaps for `maintenance info sections` sections
which have a start address of 0x0. While there could potentially be a
coredump file from a binary with start=0x0, this should work in most
cases.
We could in theory do a slighty better: we could take the vmmap at 0 and
try to read memory from it. However, I am not sure if it is a good idea
to try such memory read?
