This uses the frame buffer console that KDL uses. It needs some work,

Use fast clearing of visible screen for splash
memset uses rep stosb on x86 during boot, with memory
not set to write-combining, which makes it slow.
Instead we do aligned writes of 2 x four bytes
Use fast clearing of visible screen for splash
memset uses rep stosb on x86 during boot, with memory
not set to write-combining, which makes it slow.
Instead we do aligned writes of 2 x four bytes at once.
Only clear the minimum of size and width * height * 4
UEFI framebuffer size can be huge, upto 512MB here,
and rep stosb seems to be around 25-30MB/s
This is written as generic as possible to work on
old compilers and different platforms, without
expecting boot memset to be optimized.
This makes it almost unnoticable compared to not
clearing.

Don't clear video mem on UEFI, efi video mode refactor
Writes to videomem is slow without memory remapping
Can't do the mapping without leaving UEFI, so skipping
the clear. Afaict it should always be cleared by UEFI
This saves ~10 seconds of booting on my machine
(1920*1080*4 bytes)
EFI video mode (should have been it's own commit)
* Only do strcmp if there are enough params
* break when found

Factor out the splash image display logic too.

Factor out the RLE and blitting functions from bios_ia32 to platform/generic/ so it can be reused by other platforms.
