Seems that the 'if (cursor_enabled)' check in
video_console_fixup_cursor() that was removed in chromium.org 1f880bca0 really
meant to check for 'if (console)'. Looks like the whole video console
driver is built extra robust to not fail no matter how screwed up the
console is, so let's add this missing check here as well. Also fixed up
a few other missing 'if (!console)' checks while I'm at it.
However, what payloads should really be doing is check the return value
of video_(console_)init() and not call the other video functions if that
failed. This also adapts video_console_init() to correctly pass through
the return value for that purpose (something that seems to have been
overlooked in the dd9e4e58 refactoring).

The video console runs a video_console_fixup_cursor() function after
every printed character to make sure the cursor is still in the output
window and avoid overflows. For some crazy reason, this function does
not run when cursor_enabled is false... however, that variable is only
about cursor *visibility*, and it's imperative that we still do proper
bounds checking for our output even if the cursor itself doesn't get
displayed (otherwise we can end up overwriting malloc cookies that cause
a panic on the next free() and other fun things like that).
In fact, there seems to be no reason at all to even keep track of the
cursor visibility state in the generic video console framework (the
specific backends already do it, too), so let's remove that code
entirely. Also set the default cursor visibilty in the corebootfb
backend to 0 since that's consistent with what the other backends do.
BUG=None
TEST=Turn on video console on Big, generate enough output to make it
scroll, make sure it does not crash.

The console output driver framework in libpayload is currently built on
the putchar primitive, meaning that every driver's function gets called
one character at a time. This becomes an issue when we add drivers that
could output multiple characters at a time, but have a high constant
overhead per invocation (such as the planned GDB stub, which needs to
wrap a special frame around output strings and wait for an
acknowledgement from the server).
This patch adds a new 'write' function pointer to the
console_output_driver structure as an alternative to 'putchar'. Output
drivers need to provide at least one of the two ('write' is preferred if
available). The CBMEM console driver is ported as a proof of concept
(since it's our most performace-critical driver and should in theory
benefit the most from less function pointer invocations, although it's
probably still negligible compared to the big sprawling mess that is
printf()).
Even with this fix, the problem remains that printf() was written with
the putchar primitive in mind. Even though normal text already contains
an optimization to allow multiple characters at a time, almost all
formatting directives cause their output (including things like
padding whitespace) to be putchar()ed one character at a time.
Therefore, this patch reworks parts of the output code (especially
number printing) to all but remove that inefficiency (directives still
invoke an extra write() call, but at least not one per character). Since
I'm touching printf() core code anyway, I also tried to salvage what I
could from that weird, broken "return negative on error" code path (not
that any of our current output drivers can trigger it anyway).
A final consequence of this patch is that the responsibility to prepend
line feeds with carriage returns is moved into the output driver
implementations. Doing this only makes sense for drivers with explicit
cursor position control (i.e. serial or video), and things like the
CBMEM console that appears like a normal file to the system really have
no business containing carriage returns (we don't want people to
accidentally associate us with Windows, now, do we?).
BUG=chrome-os-partner:18390
TEST=Made sure video and CBMEM console still look good, tried printf()
with as many weird edge-case strings as I could find and compared serial
output as well as sprintf() return value.

When libpayload header files are included in the payload itself, it's possible
that the payloads config settings will conflict with the ones in libpayload.
It's also possible for the libpayload config settings to conflict with the
payloads. To avoid that, the libpayload config settings have _LP_ (for
libpayload) added to them. The symbols themselves as defined in the Config.in files
are still the same, but the prefix added to them is now CONFIG_LP_ instead of just
CONFIG_.
