...
Note : all error codes are changed by this new version,
but it's expected to be the last change for existing codes.
Codes are now grouped by category, and receive a manually attributed value.
The objective is to guarantee that
error code values will not change in the future
when introducing new codes.
Intentionnal empty spaces and ranges are defined
in order to keep room for potential new codes.

ZDICT_finalizeDictionary() flipped comparison
...
`ZDICT_finalizeDictionary()` had a flipped comparison.
I also allowed `dictBufferCapacity == dictContentSize`.
It might be the case that the user wants to fill the dictionary
completely up, and then let zstd take exactly the space it needs
for the entropy tables.
