New vCtrlC packet, non-stop mode equivalent of \003
There's currently no non-stop equivalent of the all-stop ^C (\003)
"packet" that GDB sends when a ctrl-c is pressed while a foreground
command is active. There's vCont;t, but that's defined to cause a
"signal 0" stop.
This fixes many tests that type ^C, when testing with extended-remote
with "maint set target-non-stop on". E.g.:
Continuing.
