If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
to achieve the desired timeout.
* serial.h (serial_t): Add field timeout_remaining.
cleanup chain, not directly.
* ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
munging the timeout due to the limited range of c_cc[VTIME].
Change all references to stdout/stderr to gdb_stdout/gdb_stderr.
Replace all calls to stdio output functions with calls to
corresponding _unfiltered functions (`fprintf_unfiltered')
Replaced calls to fopen for output to gdb_fopen.
Added sufficient goo to utils.c and defs.h to make the above work.
The net effect is that stdio output functions are only directly used
in utils.c. Elsewhere, the _unfiltered and _filtered functions and
GDB_FILE type are used.
In the near future, GDB_FILE will stop being equivalant to FILE.
The semantics of some commands has changed in a very subtle way:
called in the right context, they may cause new occurences of
prompt_for_continue() behavior. The testsuite doesn't notice anything
like this, though.
Please respect this change by not reintroducing stdio output
dependencies in the main body of gdb code. All output from commands
should go to a GDB_FILE.
Target-specific code can still use stdio directly to communicate with
targets.
* inflow.c, ser-unix.c, ser-go32.c, ser-tcp.c, serial.h,
terminal.h: Move all the process group stuff back to inflow.c;
that's a better place for it and fixes problems with trying to get/set
the process group of a tty we're doing remote debugging on.
* terminal.h: Skip the redefine crap if HAVE_TERMIOS.
simply save encode this fact as the process group and return
success rather than an error.
(set_tty_state): if process group is -1, do not reset the
process group.
(hardwire_reachar): comment change.
* nindy-share/*, remote-nindy.c: Extensive hacking to make it
conform to GDB conventions like using memcpy not bcopy, serial.h,
etc. This is to make it host on Solaris, AIX, etc.

<memory.h>.
Include <malloc.h> rather than declaring malloc functions ourself.

out whether we care about lack of job control, rather than __GO32__.
* utils.c: Include serial.h not terminal.h
(quit): Use job_control not TIOCGPGRP.
* terminal.h: Don't undefine TIOCGPGRP.

* ser-unix.c: Add process group to ttystate.
[HAVE_SGTTY]: Add tchars, ltchars, and lmode to ttystate.
* inflow.c: Include serial.h not terminal.h.
Use serial.h stuff to replace most of the maze of #ifdef's.
* inflow.c, main.c, inferior.h: make gdb_has_a_terminal a function.
* serial.h: Document SERIAL_SET_TTY_STATE as being immediate.
* ser-unix.c: Use TIOCSETN not TIOCSETP so it is true.
* serial.h, ser-unix.c, ser-go32.c, ser-tcp.c:
Add SERIAL_PRINT_TTY_STATE, SERIAL_NOFLUSH_SET_TTY_STATE, and
SERIAL_SET_PROCESS_GROUP.
* inflow.c: Use them.
* config/xm-svr4.h, config/rs6000/xm-rs6000.h, config/sparc/sun4os4.h:

* (dos_async_init): Make usage message reflect requested port #.
* ser-tcp.c (tcp_open): Terminate hostname properly to prevent
random hostname lookup failures. Add nicer message for unknown
host error. (wait_for): Wake up in case of exceptions. Also,
restart select() if we got EINTR.
* ser-unix.c (wait_for): Restart select() if we got EINTR.
* serial.c: (serial_close): Clean up code.
* defs.h (memcmp): Add decl for memcmp to #ifndef MEM_FNS_DECLARED.
* findvar.c (write_register): See if we are writing back the same
value that's already in the register. If so, don't bother.
* remote.c (putpkt, getpkt): Improve handling of communication
problems.
* ser-go32.c: Prototype it to death. Update serial_ops and add
dummy routines where appropriate.
* ser-tcp.c: New module to implement serial I/O via TCP
connections.
* ser-unix.c: Clean up getting/setting of tty state. Get rid of
SERIAL_RESTORE, add SERIAL_{GET|SET}_TTY_STATE interfaces.
* serial.c: Add start of support for connect command.
(serial_open): Distinguish between tcp and local devices.
* serial.h (struct serial_ops): Get rid of restore, add
get_tty_state and set_tty_state. Define protoypes and macros for
this mess.
* gdbserver/remote-utils.c: Add tcp support. (readchar): Do
some real buffering. Handle error conditions gracefully.
* gdbserver/remote-inflow-sparc.c: Update to remote-inflow.c
(Lynx), remove lots of cruft.
constants with slightly more portable definitions (still depends
on 2's complement arithmetic though).
* config/i386/nm-linux.h: Define NO_SYS_REG_H for no <sys/reg.h>.
* i386v-nat.c (sys/reg.h): Conditionalize include on
NO_SYS_REG_H. Linux doesn't have <sys/reg.h>.
* ser-unix.c (termio.h): Include <termio.h> like other files that
include termio.h, not <sys/termio.h> which may not exist (on
linux for example).
(putpkt, getpkt): Use new return codes for SERIAL_READCHAR.
* ser-go32.c: Return -1 on most failures, 0 on most successes,
and use new return codes for go32_readchar().
* ser-unix.c: Ditto. Also, move error handling up to caller for
SERIAL_SETBAUDRATE().
* serial.c (serial_open): Internal call, not SERIAL_OPEN to get
to specific routine.
(serial_close): New routine to wrap around device close routine.
serial.h: Clean & document return values more clearly.
These implement a new serial line interface for talking to remote
targets.
* configure.in: Link ser-hardwire.c to ser-unix.c for all hosts,
EXCEPT go32, which gets ser-go32.c.

converted later.
* ser-bsd.c, ser-termios.c: Removed.
* serial.c: New. Implements common operations for all serial
types.
* ser-unix.c: New. Unix specific serial operations for various

config/m68k/apollo68b.mh, config/sparc/sun4os4.mh: Remove

configure.in.
