Squashed commit of the following:
...
drivers/syslog: Channel configuration. Decouple SYSLOG_SERIAL_CONSOLE and ARCH_LOWPUTC. Since some hardware can output log to the special debug channel not serial.
drivers/syslog/vsyslog.c: Support pre-pending a prefix string to log output if enabled. This very useful to identify which cpu send out the log in AMP SoC.
drivers/syslog/vsyslog.c: Make timestamp output same as linux kernel. It's very useful if NuttX syslog retarget to Linux syslog.

Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and debug wrappers -- does not return a value. Rename _vsyslog to nx_vsyslog. Use internal nx_vsyslog in the few cases where a return value is required.

syslog: Avoid flushing syslog_stream buffer, if possible, until lib_vsprintf() completely parses the format. This assures that the flush will flush the entire output, even data that may potentially follow the linefeed. And, in that case, it cannot be interleaved with other devug output. Suggested by Jussi Kivilinna.

When syslog message has addition characters after last new-line. With buffering those now get lost as vsyslog does not flush output after lib_sprintf. Additional trailing characters could be ANSI escape sequence to reset state that message setups. For example, macro here uses colors and resets state after actual message (including '\n'):
...
With flushing added to vsyslog, then there is problem that next syslog line might come from other task before reset sequence, causing wrong line getting color. This could be avoided by not flushing on '\n' but only if IOB is full and/or at end of vsyslog. Would this make sense?

Remove lowsyslog(). The new syslog() includes all of the functionality of lowsyslog(). No longer any need for two interfaces.

Need to pass va_list as a reference to vsyslog. This is because va_list is a structure in some compilers and passing of structures in the NuttX sycalls does not work.

Move the OS intensive part of vsyslog and vlowsyslog to drivers/syslog/vsyslog.c and vlowsyslog.c. Also move lib_syslogstrem to drivers/syslog/syslogstream.c
