Move userland PALcode handling into linux-user main loop so that we can send signals from there. This also makes alpha_palcode.c system-level only, so don't build it for userland. Add defines for GENTRAP PALcall mapping to signals. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
