linux-user: Add missing termbits types and values definitions
This patch introduces missing target types ('target_flag_t', 'target_cc_t',
'target_speed_t') in a few 'termibts.h' header files. Also, two missing
values ('TARGET_IUTF8' and 'TARGET_EXTPROC') were also added. These values
were also added in file 'syscall.c' in bitmask tables 'iflag_tbl[]' and
'lflag_tbl[]' which are used to convert values of 'struct termios' between
target and host.

linux-user: Don't call gdb_handlesig() before queue_signal()
The CPU main-loop routines for linux-user generally
call gdb_handlesig() when they're about to queue a
SIGTRAP signal. This is wrong, because queue_signal()
will cause us to pend a signal, and process_pending_signals()
will then call gdb_handlesig() itself. So the effect is that
we notify gdb of the SIGTRAP, and then if gdb says "OK,
continue with signal X" we will incorrectly notify
gdb of the signal X as well. We don't do this double-notify
for anything else, only SIGTRAP.
Remove this unnecessary and incorrect code from all
the targets except for nios2 (whose main loop is
doing something different and broken, and will be handled
in a separate patch).
This bug only manifests if the user responds to the reported
SIGTRAP using "signal SIGFOO" rather than "continue"; since
the latter is the overwhelmingly common thing to do after a
breakpoint most people won't have hit this.
