Add test for `.' overflows, remove the output size argument from ossl_a2ulabel() since it was never used and greatly complicated the code. Convert ossl_a2ulabel() to use WPACKET for building the output string. Update the documentation to match the new definition of ossl_a2ulabel(). x509: let punycode handle the '\0' string termination. Saves a memset(3) and some size fiddling. Also update to deal with the modified parameters.
