New Revision: 70539

URL: http://svn.reactos.org/svn/reactos?rev=70539&view=rev
Log:
[BOOTLIB]: ACPI support (RSDP, XSDT/RSDT and arbitrary table lookup + mapping)
[BOOTLIB]: Additional text and graphics console support. Among other things, we have now
gained the ability to fill a buffer with a particular color.
[BOOTLIB]: OEM Bitmap (ACPI 5!) support.
[BOOTMGR]: Continue making a few more initialization calls now that bootlib supports more
functionality.
