0d9aedfcea Downgrade a few INFO level logs to DEBUG again. Also add two or three new 
logs in cases where a calling function's log was downgraded and we wouldn't
get any log message otherwise.

Add entropy in 512-bit chunks, not 160-bit chunks.  (This latter

f6dbe5a0d4 Refactor crypto error handling to be more like TLS error handling: 
crypto_perror is a no-no, since an operation can set more than one
error.

Also, fix a bug in the unix crypto_seed_rng: mixing stdio with
/dev/urandom is a bad idea, since fopen can make all kinds of weird
extraneous syscalls (mmap, fcntl, stat64, etc.) and since fread tends
to buffer data in big chunks, thus depleting the entropy pool.
