3a4f820d62 Replace all random functions with isc_random, isc_random_buf and isc_random_uniform API. 
The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.

The isc_random family of functions internally use these CSPRNG (if available):

1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library

4807.	[cleanup]	isc_rng_randombytes() returns a specified number of
			bytes from the PRNG; this is now used instead of
