users may call crypto_has_acomp to confirm the existence of acomp before using crypto_acomp APIs. Right now, many of acomp have scomp backend, for example, lz4, lzo, deflate etc. crypto_has_acomp will return false for them even though they support acomp APIs. One possible way to make has_acomp true for them is calling this APIs like crypto_has_acomp("xxx", CRYPTO_ALG_TYPE_SCOMPRESS, 0); But it looks quite weird.
