clean up bilinear filter make reference version of bilinear_filters short. use reference versions of bilinear_filters and sub_pel_filters when possible. recognize that Width was being passed into filter_block2d_bil_first_pass multiple times. ARM version had already fixed this. propegate to C. change references to src_pixels_per_line to src_pitch and standardize on src/dst (instead of input/output). recognize that first_pass is only run in the verticle and second_pass only horizontal. ARM version had already fixed this. propegate to C Change-Id: I292d376d239a9a7ca37ec2bf03cc0720606983e2

Fix linker warnings for bilinear filters The declaration of the bilinear filters specified an alignment clause in the implementation file but not in the header. This turned out to be harmless, but it did cause linker warnings to be emitted when building on Windows. The (extern) declaration in the header was changed, to match the declaration in the implementation. Change-Id: I44be89b1572fe9a50fa47a42e4db9128c4897b04

Fix pedantic compiler warnings Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966
