* VM scripts can now be configured via environment variables:
PBOTVM_DOMAIN, PBOTVM_TIMEOUT, PBOTVM_SERVER, PBOTVM_SERIAL,
PBOTVM_HEART, PBOTVM_NOREVERT
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.
