/*
* Check syntactic correctness.
*
* When setting a pubkey (Set()) or deserializing fails (its header bytes
* don't match the length of the data), the size is set to 0. Thus,
* by checking size, one can observe whether Set() or deserialization has
* failed.
*
* This does not check for more than that. In particular, it does not verify
* that the coordinates correspond to a point on the curve (see IsFullyValid()
* for that instead).
*
* Note that this is consensus critical as CheckECDSASignature() calls it!
