In addition to retrieving the device capabilities, a VF may also need to
retrieve the mapping of its ring pairs to crypto and or compression
services in order to work properly.
Make the VF receive the ring-to-service mappings from the PF by means of a
new REQ_RING_SVC_MAP Block Message and add the request and response
logic on VF and PF respectively. This change requires to bump the PFVF
protocol to version 4.

Allow the VF driver to get the supported device capabilities through PFVF,
by adding a new block message, the Capability Summary.
This messages allows to exchange the capability through masks, which
report, depending on the Capability Summary version, up to the following
information:
- algorithms and/or services that are supported by the device (e.g.
symmetric crypto, data compression, etc.)
- (extended) compression capabilities, with details about the compression
service (e.g. if compress and verify is supported by this device)
- the frequency of the device
This patch supports the latest Capabilities Summary version 3 for VFs,
but will limit support for the PF driver to version 2. This change also
increases the PFVF protocol to version 2.

Reorganize the structure of the PFVF code by moving the content of
adf_pf2vf_msg.c and adf_vf2pf_msg.c.
The logic that handles high level messages has been moved to
adf_pfvf_pf_msg.c and adf_pfvf_vf_msg.c.
The implementation of low level communication primitives and the
protocol is now included in adf_pfvf_pf_proto.c and adf_pfvf_vf_proto.c.
In addition, the file adf_pf2vf_msg.h has been renamed in adf_pfvf_msg.h
since it common to PF and VF and the copyright date for the touched
files has been updated.
