This is a step towards decoupling the PASN initiator and responder
implemenentation is decoupled from the wpa_s and hapd contexts and
moving to a common folder for better abstraction. Move the struct
wpas_pasn definition to a common file for initiator and responder. The
idea is to provide a library libpasn.so from PASN common code. Include
C++ compatibilty wrapper to extend libpasn.so support for modules using
cpp code base.
This library can be used in applications implementing protocols based on
the PASN handshake.

The initial wpa_drv_get_mlo_info() implementation cleared only the
valid_links information within struct driver_sta_mlo_info before trying
to fetch the information from the driver. While this is likely going to
work fine in practice, this can result in static analyzer warnings on
use of uninitialized memory (e.g., mlo.assoc_link_id could have been
read if wpa_s->valid_links was set to a nonzero value). In any case, it
is better to avoid such unnecessary warnings by clearing the full data
structure before using it.
