Add entities for following Bluetooth man pages: [1]

btsockstat(1), rfcomm_sppd(1), bcmfw(8), bt3cfw(8),
hccontrol(8), hcsecd(8), hcseriald(8), l2control(8),
l2ping(8), rfcomm_pppd(8).

While I am here:

• put kadmind(8) entitiy after k5su(8) otherwise

	  doc/share/examples/check-manref.sh complains.

• add entities for CTASSERT(9), rman(9).
