This patch modifies HEVC mc MIPS-SIMD optimized code according to improved version of generic macros.

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 was probably broken some time ago. The breakage is now part of the
ABI. For example, we have:

    AV_PIX_FMT_XYZ12BE
    AV_PIX_FMT_NV16
    AV_PIX_FMT_NV20LE

AV_PIX_FMT_NV20LE is wrong. It has the value 113, but as little-endian
format it should be even. This must have been quite obvious when these
formats were added (because of the AV_PIX_FMT_XYZ12BE entry), but
nobody cared or knew about this.

The future libavutil major bump will also break this additionally,
because disabling FF_API_VDPAU will remove an odd number of entries from
the middle of the enum.

Simplifies the code and makes it build on certain compilers
running out of registers on x86.

This patch moves HEVC code of uni mc cases to new file hevc_mc_uni_msa.c.
(There are total 5 sub-modules of HEVC mc functions, if we add all these modules in one single file, its size would be huge (~750k) & difficult to maintain, so splitting it in multiple files)
This patch also adds new HEVC header file libavcodec/mips/hevc_macros_msa.h

Such tables are not used anywhere currently, but that should change.

Code is small enough that there is no advantage in a separate function.

This is needed for proper operation with seeking.

Otherwise it will never be reset, and remain "stuck" in this state
forever. Can happen when seeking: the decoder will receive fragments
from different file positions, which triggers the condition easily.

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 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.
