_Roxen.http_decode_string: dont leak on error

Move the check for correct hexadecimal sequences into the first loop,
which calculates the length. This prevents the string builder to leak

removed from the second loop, as they are already done in the first.
mpz_set_si works in GMP 4.0 and forward.
mpz_getlimbn works correctly in GMP 4.0 and forward.
Use mpz_init2 as identifier or GMP 4.0
