Use CONFIG_CNSS_OUT_OF_TREE to control if CNSS family drivers are
built from in-kernel-tree source or out-of-kernel-tree source since
the exposed header files will be in different paths. This is also
for backward compatibility.

netlink_broadcast() will return -ESRCH when diagLog socket in
userspace is not present, then massive and repetitive error log
shown as below will be print. To address this, don't print
error log if netlink socket is absent.
"Ptt Socket error sending message to the app!!"
"ptt_sock_send_msg_to_app:Failed sending Msg Type [0x5050] to pid"

Currently, the code present to take care of the PTT msgs in case of
non-CNSS_GENL is not being used. Thus, cleanup the path for the same.

Per the Linux Kernel coding style, as enforced by the kernel
checkpatch script, pointers should not be explicitly compared to
NULL. Therefore within utils replace any such comparisons with logical
operations performed on the pointer itself.

Currently the NL MSG handlers for WLAN_NL_MSG_CNSS_DIAG, ANI_NL_MSG_PUMAC
and ANI_NL_MSG_PTT are not deregistered during hdd_wlan_exit which can
causes a page fault if NL issues cld80211_doit for these NL messages
when the WLAN is not up.
Add Deregsiter APIs for all the NL MSGs to call as part of
hdd_exit_netlink_services during hdd_wlan_exit.

There is a possibility of buffer overread while processing PTT
commands, because of packet length check is missing.
While processing PTT commands, validate packet length to make sure
there is no buffer overread.

The Linux kernel version 4.12 introduced an API change to nla_parse().
Add conditional compilation to call nla_parse with the correct
parameters based on the version of the linux kernel being compiled
against.

In ptt_cmd_handler(), validate that the command attribute is of
minimum allowed size. This prevents parsing of rogue command
format. Also add audit comment to express the intent why policy
table is not used while using nla_parse API.

Currently user space communication functions[cnss diag, PTT socket app]
in host driver uses netlink user sockets which is a security concern from
Linux Android SE policies.
Add support for to use netlink family cld80211 which uses generic
netlink sockets.
