Changed default legacy support to v0.5+

thus dropping read support for v0.4.

It's always possible to re-enable it, by changing build macro ZSTD_LEGACY_SUPPORT to 4.

         `ZSTD_LEGACY_SUPPORT=3` means : "support legacy formats >= v0.3.0", and so on.
-        Starting v0.8.0, all versions of `zstd` produce frames compliant with specification.
-        As a consequence, `ZSTD_LEGACY_SUPPORT=8` (or more) doesn't trigger legacy support.
-        Also, `ZSTD_LEGACY_SUPPORT=0` means "do __not__ support legacy formats".
+        Currently, the default library setting is `ZST_LEGACY_SUPPORT=5`.
+        It can be changed at build by any other value.
+        Note that any number >= 8 translates into "do __not__ support legacy formats",
+        since all versions of `zstd` >= v0.8 are compatible with v1+ specification.
+        `ZSTD_LEGACY_SUPPORT=0` also means "do __not__ support legacy formats".
         Once enabled, this capability is transparently triggered within decompression functions.
         It's also possible to invoke directly legacy API, as exposed in `lib/legacy/zstd_legacy.h`.
         Each version also provides an additional dedicated set of advanced API.
         For example, advanced API for version `v0.4` is exposed in `lib/legacy/zstd_v04.h` .
         Note : `lib/legacy` only supports _decoding_ legacy formats.
