bcb011a306 Various fixes to lib/isc/stats.c 
* Re-introduce ISC_STATS_LOCKCOUNTERS so that it is an optional feature (it adds lock contention)
* Fix desired rwlock type in lock calls (they were opposite of what should be used)
* Add locking to isc_stats_set()
* Inline create_stats()

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

6ddbca6f2b isc_buffer_*(): if source can be NULL, only call memmove() when length is non-zero 
Certain isc_buffer_*() functions might call memmove() with the second
argument (source) set to NULL and the third argument (length) set to 0.
While harmless, it triggers an ubsan warning:

    runtime error: null pointer passed as argument 2, which is declared to never be null

Modify all memmove() call sites in lib/isc/include/isc/buffer.h and
lib/isc/buffer.c which may potentially use NULL as the second argument
(source) so that memmove() is only called if the third argument (length)
is non-zero.

each, the debuglink table itself was consuming 1GB+ of memory.
