Move the public ZBUFF compatibility layer into the Rust static archive while
keeping stream contexts opaque and forwarding to the current ZSTD streaming
APIs. The deprecated C translation units are now declaration-only shims, so
the compatibility symbols work in compression-only and decompression-only
feature builds without duplicating private context layouts.
Test Plan:
- cargo test --manifest-path rust/Cargo.toml
- cargo clippy --manifest-path rust/Cargo.toml --all-targets -- -D warnings
- cargo +nightly fmt --manifest-path rust/Cargo.toml -- --check
- make -B -C lib libzstd.a ZSTD_LIB_DEPRECATED=1 V=1
- C ZBUFF compress/decompress smoke test against the rebuilt static archive
Depends-on: Rust compression and decompression streaming ABI ports
* deprecate advanced streaming functions
* remove internal usage of the deprecated functions
* nit
* suppress warnings in tests/zstreamtest.c
* purge ZSTD_initDStream_usingDict
* nits
* c90 compat
* zstreamtest.c already disables deprecation warnings!
* fix initDStream() return value
* fix typo
* wasn't able to import private symbol properly, this commit works around that
* new strategy for zbuff
* undo zbuff deprecation warning changes
* move ZSTD_DISABLE_DEPRECATE_WARNINGS from .h to .c

`lib/deprecated` is no longer built by zstd's bundled build files. However,
users may try to build these files when they import the source tree into
their own build systems. And if they have `-Wdeprecated-declarations` on,
this can produce warnings.
This PR migrates these files away from using deprecated declarations.
This addresses #2767.
