Adds tcsendbreak (vXE-dIUIZlE), tcdrain (brGGJWsZauw), tcflush
(FxHW5NuEXsY), tcflow (OG8xRaGIpqk), tcgetpgrp (5OEl1mRhUm0) and
tcsetpgrp (YMuesZTyTl4) next to tcgetattr and tcsetattr in
File/src/Terminal.cpp. The NIDs come from tools/nid_names.py and match
aerolib.csv (zecoxao/sce_symbols 2883963a).
They follow FreeBSD 11.4 lib/libc/gen/termios.c (8c639945), which
implements each one over a terminal ioctl: tcflush returns EINVAL for a
queue other than TCIFLUSH, TCOFLUSH or TCIOFLUSH and tcflow for an
action outside TCOOFF..TCION before the descriptor is used; every other
call fails with the error the merged tcgetattr gives (EBADF for a closed
descriptor, ENOTTY for a file or pipe, EADDRNOTAVAIL or EOPNOTSUPP for a
socket, per soo_ioctl and in_control/in6_control). tcsendbreak fails on
TIOCSBRK before its 0.4 s pause, and tcflow's TCIOFF/TCION fail in
tcgetattr. FreeBSD's pipe_ioctl answers TIOCGPGRP/TIOCSPGRP on a pipe or
FIFO with the SIGIO owner, which is not modelled, so tcgetpgrp and
tcsetpgrp throw on a host pipe above descriptor 2.
Titles (homebrew catalog #1578), predicted stops from registry order:
- PS5MC PPSA99420 imports tcsendbreak (442), tcdrain (443), tcflush
(444), tcflow (445), tcgetpgrp (462) and tcsetpgrp (463); once pause
and setrlimit are in, it stops at
"FAIL: unresolved ELF import vXE-dIUIZlE from libkernel.prx".
- XPSemu PPSA97358 imports tcsendbreak (214), its first uncovered import
after execv, sigwait, setrlimit, mlockall, setuid and getopt:
"FAIL: unresolved ELF import vXE-dIUIZlE from libkernel.prx".
guest_terminal covers each call over stdin, stdout, stderr, a file, both
pipe ends and an AF_INET socket, the EINVAL cases (also on -1), and
EBADF for -1, a closed socket, a closed pipe and a closed file.

dup and dup2 carry the random device over to the new descriptor, and
select reports /dev/random and /dev/urandom ready, as the select entry
already says.
