opal_console: fix serial console output corruption on powerpc64

Adds OPAL_CONSOLE_WRITE error handling and implements a call to
OPAL_CONSOLE_WRITE_BUFFER_SPACE to verify if there's enough space
before writing to console.

This fixes serial port output getting corrupted on fast writes, like
on "dmesg" output.

Tested on Raptor Blackbird running powerpc64 BE kernel

Extract eventfilter declarations to sys/_eventfilter.h

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.

EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).

As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.

LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).

No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

Support multiple OPAL consoles, and don't crash if uart is not stdout

Summary: If the chosen console is not the OPAL uart, but OPAL uart devices
exist, the console device doesn't attach properly, and faults in the interrupt
handler, with a NULL pointer dereference. To fix this, and as a byproduct, also
support multiple OPAL consoles, refactor to have the console getc callback use
the appropriate softc instead of the global console_sc, which may be NULL in the
case of a different device being the console.

PowerNV: add buffer for OPAL console

Avoid the lock in vtophys() by providing a static direct-mapped
spinlock- protected output buffer to use when the console driver
cannot acquire locks for some reason. This allows the idle thread
to use printf() (e.g. the SMP startup messages) without crashing
the kernel.
