subsequent InterlockedIncrement will keep the counter at the correctly
decremented value and also detect when there are pending signals.

variable.
(fhandler_console::fhandler_console): Add definition for
variable "meta_mask" used to determine if a keystroke should be
preceded by META in the client console stream. Set meta_mask
based on whether or not user's keyboard language is English -
non-English keyboards pass AltGr (right <ALT>) unmolested,
whereas English keyboards now interpret left- and right-<ALT>
as META.
