Modified Files:
        src/sys/kern: kern_entropy.c

Log Message:
New sysctl kern.entropy.gather=1 to trigger entropy gathering.

Invokes all on-demand RNG sources.  This enables HWRNG driver
developers to use a dtrace probe on rnd_add_data to examine the data
coming out of the HWRNG:

dtrace -n 'fbt::rnd_add_data:entry /args[0]->name == "amdccp0"/ {
   ...examine buffer args[1] length args[2]...
}'
