add more checks to PICTURE metadata: at most one type=1 and type=2 blocks, type=1 block must be 32x32 pixel PNG

merge down from merged-API-layer branch: cvs -q up -dP -j API_LAYER_MERGING_BASELINE -j API_LAYER_MERGING_BRANCH

fix calculation bugs in encode_subframe_(): max_qlp_coeff_precision when qlp_coeff_prec_search; account for qlp coeff overhead in guessing the best lpc order; default to hann instead of rectangular window on assertion failure

add FLAC__MANDATORY_VERIFY_WHILE_ENCODING ifdefs which will be turned on when compiling with new asm optimzations

finished integerized flavor of library; sections with floating point are either #ifdef'd out or written in fixed-point

first pass at making an integer-only flavor of the libraries.  move FLAC__real out of ordinals.h to src/libFLAC/include/private/float.h, add FLAC__double and FLAC__float and use these everywhere instead of double and float, and don't typedef FLAC__real/float/double when building in integer-only mode.  still need to provide integer substitutes in several places.

add new requirements to ogg mapping: vorbis comment block must come second after streaminfo; first packet must have a packet type byte of 0x7f; packet 0 version must be followed by a 2-byte count of the # of header packets

tweaks to the MD5 routines; they need to be exported when building a windows DLL since the seekable stream decoder in libOggFLAC secretly uses them
