VM socket communication is superior to VM serial communication in
every way. Unfortunately at this time only Linux supports them.
Fortunately, that's 99% of PBot's userbase.
If you're not using Linux or if you're using an older Linux that
does not support VM sockets, the PBot VM scripts will gracefully
fallback to using the serial connection. You may explicitly
disable VM socket connection attempts by setting PBOTVM_CID=0.
Some recent changes in the default `gdb` debugging format has broken
some gdb functionality, notably the `info macro` command.
Specifying the `dwarf-2` format restores this functionality.
This is expected to take three commits to complete. This first initial
commit does the following:
- Begin initial rough-draft of doc/VirtualMachine.md
- Begin initial refactoring of scripts
The next commit will polish up the initial rough-draft and refactoring.
The final commit will quality-check everything and fix anything overlooked.
