Input validation

[siilike]

I was wondering what would be the best way to perform input validation to avoid buffer overflows.

For instance, if the application receives a 10-byte message that is a binary VPack value with length set to 100 bytes.

There is a class named velocypack::Validator, which can be used for input validation.
It has a validate method which should be given a pointer to the input plus the length of the input.
There are several examples of how to use it in the tests.
