efd1b838e6 syslog: Add sc_write_force callback 
It is used to write the log message to the channel immediately
when the log message is generated in the interrupt context, which
is faster than the normal force callback.

71c8265e2d drivers/syslog: add mutex to syslog_default_write 
This commit reverts 19f269e54b and
substitutes the semaphore to a mutex, used as a locking mechanism
to avoid syslog messages being messed.

Considering SMP, threads running on different CPUs could call
syslog_default_write simultaneously. It then calls `up_nputs` that,
in most of the implementations, calls `up_putc` multiple times to
write to the serial. So, calling it at the same would cause syslog
messages to interfere with each other.

`up_nputs` and `up_putc` are low-level functions that could be used
during initialization and by the interrupt handler. Hence, it isn't
advisable to implement any locking mechanism on them. On the other
hand, syslog can also be used from the interrupt: if the interrupt
buffer is selected (`CONFIG_SYSLOG_INTBUFFER=y`), the syslog
messages will be flushed when we aren't serving an interrupt.
On the contrary, if it isn't set, it would call the registered
`sc_force` callback, which calls `syslog_default_putc` instead of
the lock-protected `syslog_default_write`.

335fc3dde2 syslog: Fixed a potential buffer overflow issue 
The `CONFIG_SYSLOG_MAX_CHANNELS` is user-specified, however, if the user
defines more channels than what `CONFIG_SYSLOG_MAX_CHANNELS` was defined as,
a potential buffer overflow occurred. Although the compiler does warn us about
that, we should explicitly tell the user this is an error.

1ee6083de3 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.
