val buffer and val of_bigarray implement the same

[reynir]

The two functions do exactly the same except for different messages in the Invalid_argument _ exception. It is not clear from the documentation.

It seems it was added in 6e82959#diff-1c794fc18075ec0a83c9f7b2ad768653e0ec3a60d60323e713d2f04d5b3c7c2aR82 while of_bigarray is much older.

Yes, that's about me. I don't have a real opinion about that and I think the existence of both is fine. We probably should clarify the documentation and say that they do the same things.
