09149beaf8 [1.5.0] Move zstd_errors.h and zdict.h to lib/ root 
`zstd_errors.h` and `zdict.h` are public headers, so they deserve to be
in the root `lib/` directory with `zstd.h`, not mixed in with our private
headers.

cd1551d261 [lib][tracing] Add ZSTD_NO_TRACE macro 
When defined, it disables tracing, and avoids including the header.

e4b914e663 [contrib][linux] Expose zstd headers to avoid duplication 
Expose the zstd headers in `include/linux` to avoid struct duplication.
This makes the member names not follow Kernel style guidelines, and
exposes the zstd symbols. But, the LMKL reviewers are okay with that.

49a9e070f5 [contrib][linux-kernel] Update test include stubs 
Update the test include stubs so they are able to run the current zstd
version in the kernel, so I can compare stack usage.

d2dd35ae65 [contrib][linux-kernel] Fix unaligned.h 
Fix the `unaligned.h` shim in the tests that was causing corruption in
the tests. Note that this is a problem with the test shim, not the
kernel code.

f58e9a9830 [contrib][linux] Add wrapper API 
Add the kernel wrapper API. This keeps the same API and semantics as the
existing kernel API with name changes to be more kernel style and avoid
symbol collisions with zstd.

caecd8c211 Allow user to override ASAN/MSAN detection 
Rename ADDRESS_SANITIZER -> ZSTD_ADDRESS_SANITIZER and same for
MEMORY_SANITIZER. Also set it to 0/1 instead of checking for defined.
This allows the user to override ASAN/MSAN detection for platforms that
don't support it.
