stupidgcm: batch C calls in chacha20poly1305_seal
Go has a high overhead for each C call, so batch
all openssl operations in the new C function chacha20poly1305_seal.
Benchmark results:
internal/speed$ go test -bench BenchmarkStupidXchacha -count 10 > old.txt
internal/speed$ go test -bench BenchmarkStupidXchacha -count 10 > new.txt
internal/speed$ benchstat old.txt new.txt
