This patch modifies H264 loopfilter, weighted & bi-weighted prediction MIPS-SIMD optimized code according to improved version of generic macros.
Also there are minor code alignment changes.

Overall, this patch is just upgrading the code with styling changes and will bring it in sync with MIPS-SIMD optimized latest codebase at our end.

This patch includes restructuring of existing macros and addition of more generic macros.

This change was necessary to avoid repeated review comments in remaining patches which we were about to submit.
Also this patch reduces number of code lines due to maximum use of generic macros, allows better code alignment & readability etc.

These modifications in commonly used .libavutil/mips/generic_macros_msa.h. impacts the already accepted code, hence re-submitting it in 2/4,3/4 & 4/4.
Overall, this patch set is just upgrading the code with styling changes and will bring it in sync with MIPS-SIMD optimized latest codebase at our end.

This commit silences warning(s) like:

    libavcodec/x86/fft.asm:93: warning: section flags ignored on section
    redeclaration

The cause of this warning is that because `struc` and `endstruc` attempts to
revert to the previous section state [1]. The section state is stored in the
macro __SECT__, defined by x86inc.asm to be `.note.GNU-stack ...`, through the
`SECTION` directive [2].  Thus, the `.note.GNU-stack` section is defined twice
(once in x86inc.asm, once during `endstruc`), causing the warning.

That is the first part of the commit: using the primitive `[section]` format
for .note.GNU-stack etc., which does not update `__SECT__` [2].

That fixes only half of the problem. Even without any `SECTION` directives,
`__SECT__` is predefined as `.text`, which conflicting with the later
`SECTION_TEXT` (which expands to `.text align=16`).

This reverts commit 599888a4.

The commit does not silence the warning on ELF-based systems, and will be
fixed in the subsequent commit.

Apparently it can happen that a mp3 file has junk data between id3 tag
and actual mp3 data. Skip this to avoid outputting nonsense timestamps.
(Two packets had the same timestamps, because the mp3 parser failed to
compute a frame duration.)

In this case, the junk consisted of 1044 bytes of zero, which
incidentally is the same size as normal mp3 frames in this stream. I
suspect the mp3 was edited with some tool which wiped the Xing/LAME
headers. Data near the end of the file suggests it was encoded with
"LAME3.97", but the normal Xing/LAME headers are missing. So this could
be "normal". mpg123 also attempts to skip at least 64KB of junk data by
scanning for headers.

h264.h and hevc.h are mutually exclusive due to defining some of the same
names. As such, we need to avoid forcing h264.h to be included if we want
hevc decode acceleration to be possible.

However, some of the pre-hwaccel helper functions need h264.h. To avoid
messy collisions, let's move the declaration of all those helpers to
a separate header which we will exclude for the hevc support (which will
be hwaccel-only).
