gdb/ChangeLog:
2016-04-12 Pedro Alves <palves@redhat.com>
* serial.c (serial_open, serial_fdopen_ops, do_serial_close):
Remove references to name.
* serial.h (struct serial) <name>: Delete.
The "set serial parity" command allows the user to control which
parity to use when communicating over a serial connection, rather
than having the parity hardcoded to none.

gdb/doc/ChangeLog:
* gdb.texinfo (Remote configuration): Document "set/show
serial parity" command.
I noticed that the serial_ops vtable is not const, but really it ought
to be.
This patch constifies it, removing the only mutable field in the
process.
Tested by rebuilding on x86-64 Fedora 18, both natively and using the
mingw cross tools.

* serial.c (serial_ops_p): New typedef.
(serial_ops_list): Now a VEC.
(serial_interface_lookup): Return const. Use VEC_iterate.
(serial_add_interface): Make parameter const.
(serial_open): Update.
(serial_fdopen_ops): Make 'ops' const.
(serial_pipe): Update.
* ser-tcp.c (_initialize_ser_tcp): Update.
* ser-pipe.c (_initialize_ser_pipe): Update.
* ser-unix.c (_initialize_ser_hardwire): Update.
* ser-mingw.c (_initialize_ser_windows): Update.
* ser-go32.c (dos_ops): Now const. Update.
* serial.h (struct serial) <ops>: Now const.
(struct serial_ops) <next>: Remove.
(serial_add_interface): Make parameter const.
While remote.c works with "char *" buffers most of the time, other
remote targets have binary-ish-er protocols, and choose to use
"unsigned char" throughout, like e.g., remote-mips.c or
remote-m32r-sdi.c. That results in -Wpointer-sign warnings in those
targets, unless we add casts in calls to serial_write. Since
serial_write is only concerned about sending raw host bytes out, and
serial_ops->write_prim already works with "void *"/"size_t", a similar
interface to the "write" or "send" system calls, I find it natural to
change serial_write's prototype accordingly, avoiding the need for
casts.
Tested on x86_64 Fedora 17, and also by building x86_64-mingw32
and DJGPP/go32 -hosted gdbs.
