While processing WMI_BPF_GET_VDEV_WORK_MEMORY_RESP_EVENTID,
in wma_apf_read_work_memory_event_handler() apf read callback is
invoked after wmi_extract_apf_read_memory_resp_event_tlv().
During extraction of apf attributes there is no NULL check of data
tlv when data length is non-zero. If the firmware message is wrongly
crafted with non-zero length in fixed param and NULL data then NULL
pointer dereference is seen in apf read callback.
To address this, avoid copy when data is NULL and data length is
non-zero.

Android Packet Filter 3.0 requires the framework to be able to
read and write into the APF work memory in the Firmware. It
also requires to be able to enable or disable the interpreter.
New WMI commands are defined for read/write/enable/disable
operations.
Complete the implementation of these new commands.

In implementation of Android Packet Filter, functions, variables,
definitions are named after BPF, which stands for Berkely Packet
Filter. The term was more appropriate for Link Layer packet
filters implemented in the Linux kernel, known as Linux Socket
Filters.
The term BPF is obsolete now, so rename it with the
appropriate acronym, APF.

File wmi_unified_tlv.c is bloated and adding support for upcoming
Android Packet Filter v3 is going to increase its size even more.
Create a new source file for APF related WMI modules and a header
file for declaring the API's
