For example, `ZSTD_LEGACY_SUPPORT=2` means : "support legacy formats >= v0.2.0".
Conversely, `ZSTD_LEGACY_SUPPORT=0` means "do __not__ support legacy formats".
By default, this build macro is set as `ZSTD_LEGACY_SUPPORT=5`.
By default, this build macro is set as `ZSTD_LEGACY_SUPPORT=0` (disabled).
Decoding supported legacy format is a transparent capability triggered within decompression functions.
It's also allowed to invoke legacy API directly, exposed in `lib/legacy/zstd_legacy.h`.
Each version does also provide its own set of advanced API.
