lib/zstd.h: move pragma before static
...
otherwise will cause dev-python/zstandard build failed when compiling with
clang as reported at https://bugs.gentoo.org/950259
the root cause is pycparser, which is unfixed since reported 2.5 years
ago, :(

[linux] Opt out of row based match finder for the kernel
...
The row based match finder is slower without SIMD. We used to detect the
presence of SIMD to set the lower bound to 17, but that breaks
determinism. Instead, specifically opt into it for the kernel, because
it is one of the rare cases that doesn't have SIMD support.

[zstd] Remove global variables in dictBuilder
...
D50949782 fixed a race condition updating `g_displayLevel` by disabling display.
Instead of disabling display, delete the global variable and always "capture" a local `displayLevel` variable.
This also fixes `DISPLAYUPDATE()` by requiring the user to pass in the last update time as the first parameter.

fix minor alignment warning
...
this is a prototype definition error:
`_mm_storeu_si128()` should accept a `void*` pointer,
since it explicitly states that it accepts unaligned addresses
yet requiring a `__m128i*` tells otherwise, and requires the compiler the enforce this alignment.

seems like a prototype interface error:
input parameter should have been `const void*`,
since the documentation is explicit that input doesn't have to be aligned,
but `const __m256i*` makes the compiler enforce it.
