Don't use string literals for char arrays without NUL termination
...
unsigned char foo[4] = "abcd" is not valid C++ because the string
literal "abcd" does not fit into foo due to the terminating NUL
character. This is valid in C, it will just omit the NUL character.
Fixes #962 .

schnorrsig: add extra parameter struct for sign_custom
...
This simplifies the interface of sign_custom and allows adding more parameters
later in a backward compatible way.

schnorrsig: allow signing and verification of variable length msgs
...
Varlen message support for the default sign function comes from recommending
tagged_sha256. sign_custom on the other hand gets the ability to directly sign
message of any length. This also implies signing and verification support for
the empty message (NULL) with msglen 0.
Tests for variable lengths follow in a later commit.

...
This makes the default sign function easier to use while allowing more granular
control through sign_custom.
Tests for sign_custom follow in a later commit.
