Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that
the value could serve as a default value and could be easily overridden in
configuration files like local.conf.
When using the default value for SERIAL_CONSOLES in qemux86-64,we would have
annoying messages on console complaining about respawning getty on ttyS1.
Although the value is set by purpose, at least we need to provide an easy way
to override it.

Add qemuboot-mips.inc to reduce duplicated code, the various mips bsps
which can be boot by runqemu can require qemuboot-mips.inc

qemu can freeze and stop responding if the socket buffer connected to a tcp
serial connection fills up. This happens of course when the reader of
the serial data doesn't actually read it.
This happened in the qemurunner code, because after checking for the
"login:" sentinel, data was never again read from the serial connection.
This patch solves the potential freeze by adding a thread to continuously
read the data from the console and log it. So it also will give a full log
of the console, rather than just up to the login prompt.
To simplify this patch, another serial port was also added to use for the
sole purpose of watching for the sentinel as well as being the interactive
serial port. This will also prevent the possibility of lots of debug
data on the console preventing the sentinel value from being seen due to
interleaved text.
