* rdi-share/unixcomm.c: If using cygwin32, also use the SERPORT and
PARPORT defines for win32.
(Unix_MatchValidSerialDevice): For cygwin32, valid serial port names
start with "com", not "/dev/tty".
(Unix_OpenSerial): Do not use O_NONBLOCK on cygwin32.
* rdi-share/devsw.c (DevSW_Close): Free the device's state (SwitcherState)
so that the device may be reopened.
* remote-rdi.c (mywritec): Send all output through gdb's *_unfiltered
functions, ignoring non-ASCII chars, so that non-tty UI's can snarf
the output from fputs_hook.
(mywrite): Ditto.
(arm_rdi_open): Set inferior_pid.
(arm_rdi_detach): Pop the target off the target stack so that
users can attach and detach multiple times.
(arm_rdi_close): Close the opened device and reset inferior_pid, too.
* rdi-share/Makefile.am, rdi-share/aclocal.m4,
rdi-share/configure: New files.
* rdi-share/configure.in: Rewritten to be an autoconf input file.
* rdi-share/Makefile.in, rdi-share/configure: Generated by
automake/autoconf.
* rdi-share/dbg_hif.h, etherdrv.c, hostchan.c: Use autoconf tests
to check environment.
automake/autoconfiscate rdi-share. We don't use the checks that autoconf
provides too much for now, but it'll be easier to use them if any problems
crop up in the future. (rdi-share/ is foreign code and it probably isn't
worth spending any more time than necessary messing with it.)
