since the console is normally opened three time as stdin, stdout and
stderr and remove the dependence on STANDARD_SERIAL because other type
of serial drivers also support the poll through the same codebase.

Re-check RX queue status after uart_enablerxint() and before blocking
the reading task on the receive semaphore. cdcacm (and maybe other UART
drivers) can push buffered data into the receive queue during
uart_enablerxint(), leading to a blocked task while data is already
available.

Follow the POSIX description.
SIGTSTP should be sent when the Ctrl-Z characters is encountered, not SIGSTP.
Testing:
Built with hifive1-revb:nsh (CONFIG_SERIAL_TERMIOS=y, CONFIG_SIG_DEFAULT=y and CONFIG_TTY_SIGTSTP=y)
There is a good case on sim platform:
When we input some cmd and click enter key to start application in terminal,
this context will change to application from IDLE loop. Althrough entey key '\r'
has been received to recv buffer and complete post semaphore of reader, but
pollnotify may not be called because context change. So when application run
poll function, because no events happend and poll enter wait, context will
again change to IDLE loop, this pollnotify of IDLE loop will run to send poll
events, poll function of applicaton will wake up. It's wrong!

Reported by 권석근 <kwonsksj@gmail.com>:
I found a bug at "pty.c" during ssh server implementation.
When I turn on CONFIG_SERIAL_TERMIOS and OPOST|ONLCR on pty device
for nsh console's stdin/stdout (ssh shell service), I've got system crash.
Bugs at line 687 of pty.c, pty_write()
ntotal++;
when converting '\n' to '\r\n', pty_write() will return more than requested
(+1, for example) length. and this will break caller lib_fflush(), line 150
of lib_libfflush.c.
When she get (libfflush()) bytes_nwritten which is greater than nbuffer,
nbuffer goes to negative at line 150 and eventually destroys
*stream->fs_bufpos at line 163 of lib_libflush.c
Removing ntotal++; line 687 of pty.c will fix this bug.
BTW, nsh using ptm/pty as a ssh shell service works great with libssh +
mbedtls.
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is only for rwbuffer.c and those files under drivers/serial, drivers/timers, and drivers/usbdev.
This commit completes that step for all of the files under drivers/. Still remaining: All of the files under arch/.
boards/z80/ez80/z20x/configs/w25boot/defconfig: Increase size of serial Tx buffer.
boards/z80/ez80/z20x/src/w25_main.c: Add some fflush() in necessary places. Greatly improves the usability of the UI.
boards/z80/ez80/z20x/README.txt: Trival update to README
drivers/serial/serial.c and tcdrain.c: Correct some typos.
