For payloads with UI based on CBGFX, they usually start by calling
clear_canvas or clear_screen and then draw the UI elements. However,
that makes the screen flicker.
A typical solution is to identify and minimize the area to redraw.
However for payloads with complicated UI and do not care about latency,
an alternative is to enable buffered I/O.
The new enable_graphics_buffer() will redirect all graphics I/O
into an invisible working buffer. To flush (redraw) the buffer to the
real screen, call flush_graphics_buffer(). To stop buffering, call
disable_graphics_buffer().
BUG=None
TEST=Add the enable, flush and disable calls to payload 'depthcharge',
built a firmware and boots into Chrome OS recover UI. No more
flickering. The average rendering time on x86 platform is 1.2ms.

DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead

num_entries counter is set to 0. This counter is further decremented
in function obtaining address to last entry (see root_last_entry()).
Such negative number may be further used as an index to the table.
Current implementation may lead to crash, when user removes last entry
with imd_entry_remove() and then calls for example imd_entry_add().

One of the checks inside imdr_recover() was written with the
assumption that imdr limit is always aligned to LIMIT_ALIGN. This is
true only for large allocations, thus may fail for small regions.
It's not necessary to check if root_pointer is under the limit, since
this is implicitly verified by imdr_get_root_pointer().

Previously it was allowed to create an imd_entry with size 0, however
algorithm sets the offset of such entry to the exact same address as
the last registered entry.

Add a check that root_size provided by the caller accounts for one
imd_entry necessary for covering imd_root region. Without this, we
may end up with writing on unallocated memory.
