base: Dump page table over RSP

Add a non-standard extension to the RSP protocol: the "." command
requests a dump of the simulated page table.
The dump consists of concatenated records, one record per page table
entry.  Each record contains the entry's "virtual" value written as
hex, followed by a colon (:), followed by the entry's "physical" value
written as hex, followed by a semicolon (;).

At the time of writing, one practical use of this feature (in
combination with the "shared_backstore" parameter) is extremely fast
Miranda-Ingalls simulation of JIT compilers.
