Added missing stdio.h and errno.h headers in any

files that needed them (could cause compilation failure on
some platforms). Also, rearranged the sequence with which include's
happen, so that any missing headers will be more likely to
show up as copilation errors, in the future.
rmd_yuv_utils.[ch] and rmd_block_utils.[ch] have been merged
within the former, as they deal with the same subject (converting
rgb buffers to yuv ones, with the only difference that rmd_block_utils
had the double-buffer convertions while rmd_yuv_utils dealt with the
single-buffered ones). Their headers also had the a circular dependency
(rmd_yuv_utils.h included rmd_block_utils.h and vice-versa).
rmd_math.[ch] was added. This file holds now the rmdRoundf function 
which is a portable implementation of roundf (which depends on C99).
The reasoning behind the addition of these files, is that they might
hold more purely mathematical functions, in the future.
