Updated the 5170 BIOS map, updated 8042 info, fixed some 8042 controller commands, made HLT work, and fixed the debugger's history buffer when executing a mix of real-mode and protected-mode instructions

The JSON-encoded ROM image that PCjs uses was created using the *FileDump* command-line *merge* option:

Since a MAP file ([1984-01-10.map]()) exists as well, it is automatically appended to the JSON file ([1984-01-10.json]())
when using a ROM input file (or JSON output file) with a matching filename.
Similarly, to create a binary ROM image (1984-01-10.rom), add *--format=rom* to the command-line. These operations can
only be performed using the *FileDump* command-line interface; the *FileDump* API does not support the *merge* option.
It is also possible to create a merged binary ROM image ([1984-01-10.rom](http://static.pcjs.org/devices/pc/bios/5170/1984-01-10.rom))
by adding *--format=rom* to the command-line (the default is *--format=json*).
A MAP file [1984-01-10.map]() exists as well, which is automatically appended to the JSON file when using a ROM input
file (or JSON output file) with a matching filename. For example:
These operations can only be performed using the *FileDump* command-line interface; the *FileDump* API does not support
either the *merge* option or the appending of MAP data. For the moment, the API can only dump unadorned ROM images; eg:
