Chihiro improvements: [Samuele Zannoli]

Browse Source 
* i386 cpu x87 opcodes FPREM and FPREM1 must clear status bit C2 not C0
 * Add basic management of some Nvidia APU sound registers.
 * Store modelview/projection matrices and translate/scale vectors sent to NV2A.
 * Store vertex program (vertex shader) sent to NV2A 3d accelerator.
 * Added debug command "chihiro grab_texture,<type>,<filename>", it saves to <filename> the next used texture of type <type>.
 * Fixed DXT3 and adds DXt5 texture decompression.
 * Add 3d accelerator method 0x1800 for indexed mode vertex sending.
