2021-09-07	stupidgcm: normalize constructor naming	Jakob Unterwurzacher
	New() -> NewAES256GCM() Also add missing NewChacha20poly1305 constructor in without_openssl.go.
2021-09-07	stupidgcm: revamp package documentation	Jakob Unterwurzacher
	Maybe interesting for people following https://github.com/rfjakob/gocryptfs/issues/452
2021-09-07	stupidgcm: NewChacha20poly1305: avoid slice append	Jakob Unterwurzacher
	I noticed that growslice() shows up in the cpuprofile. Avoiding slice append for the private jey copy gives a 0.6% speedup: gocryptfs/internal/speed$ benchstat old new name old time/op new time/op delta StupidXchacha-4 5.68µs ± 0% 5.65µs ± 0% -0.63% (p=0.008 n=5+5) name old speed new speed delta StupidXchacha-4 721MB/s ± 0% 725MB/s ± 0% +0.63% (p=0.008 n=5+5)
2021-09-07	stupidgcm: cache C.EVP_chacha20_poly1305()	Jakob Unterwurzacher
	2% performance improvement, almost for free. gocryptfs/internal/speed$ benchstat old new name old time/op new time/op delta StupidXchacha-4 5.82µs ± 0% 5.68µs ± 0% -2.37% (p=0.008 n=5+5) name old speed new speed delta StupidXchacha-4 704MB/s ± 0% 721MB/s ± 0% +2.43% (p=0.008 n=5+5)
