Commit 7ff57f9808 introduced a change to try to
use ATTRS{bInterfaceNumber} as a common way to match by interface number, but
this logic is broken because all the rules that we use to match by interface
number (attribute in the interface device) also require matching by idVendor
and idProduct (attributes in the physdev device), and udev rules forbid matches
from more than one parent device at a time.
We could use ATTR{bInterfaceNumber} (instead of ATTRS) to tag the actual USB
interface device, but that would require a change in all the plugins to look for
the tag not in the TTY device, but in its parent.
So, recover the original behavior, where a hidden property is created containing
the first bInterfaceNumber found in the list of parent devices, and then run
the matches against idVendor and idProduct only if the hidden property is found
with the expected value.
Rules with a single condition where a parent property is checked with != don't
work properly. E.g.:
SUBSYSTEMS!="usb", GOTO="end"
or:
ATTRS{idVendor}!="abcd", GOTO="end"
Instead, we can mix both those previous parent rules and match them:
SUBSYSTEMS=="usb",ATTRS{idVendor}=="abcd", GOTO="next"
GOTO="end"
LABEL="next"
# Apply rules here
LABEL="end"
In this case both SUBSYSTEMS and ATTRS conditions apply to the parent usb_device
(idVendor attribute is only available in the usb_device), so they apply to all
ports of the same device.

* added logic to set MMBroadbandModem's SIM_HOT_SWAP property to TRUE
* added function to enable QSS unsolicited
* added QSS unsolicited handler
This patch makes declarations bind to definitions within the same module
to prevent the potential ambiguity if referenced directly.
AddressSanitizer think they violated one definition rule, although
those symbols are accessed by address through their modules and do
not depend on the order of the libararies loaded.
