[BRLTTY] BRLTTY in GRUB2

[Dave Mielke]

The help,version,verify options now return rather than exit.

Did you add a #define which we can use to detect a Grub build?

What does opening a file yield (file descriptor, stdio stream, ...), and how 
can we passively test if input is available?

Same questions for a serial device.
