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.
Otherwise we may leave a bearer connected when ModemManager doesn't
think it's connected. Prevents a CME ERROR 277 loop on connect when
the bearer hasn't been torn down correctly.
Wait for either an E2NAP unsolicited disconnect status or (for older
devices) an ENAP poll response before completing the disconnect.
Otherwise the client may start connecting again (such as
NetworkManager autoconnect retry) and the unsolicited E2NAP may
abort it, or the modem may return CME ERROR 277 ("not disconnected
yet") for the next connection attempt.

There are a few key parts to this patch:
1) move the poll id into the Dial3gppContext structure as it is
conceptually part of the connection context data. This simplifies
context cleanup by keeping the poll id cleanup in one place.
2) move unsolicited connection status (E2NAP) handling into the
normal connection codepath, instead of completing the connection
context from the report_connection_status() E2NAP handler. This
simplifies connect code by not requiring checks for a NULL context
everywhere, and allows us to pass the Dial3gppContext structure
around instead of the Bearer object, since the Dial3gppContext
will never be comleted/freed outside the normal connection flow
codepaths like GLib idles and AT command requests.
3) use the connect context cancellable for all AT command requests
in the connect path. This lets us use the error return from
mm_base_modem_at_command_full_finish() to handle cancellation and
also not bother listening to the 'cancelled' signal of the
cancellable, since we can just check for cancellation the next time
the ENAP poll function runs.

If the modem thinks a PDP context is already active it'll return
583 errors from IPDPCFG and IPDPACT until the context is
deactivated. Deactivation was previously done after authentication,
but needs to be done before any part of the connect process to
ensure the PDP context is inactive.
The previous approach worked only if the context was being
deactivated already (which can take a bit of time) because it would
be deactivated after a few seconds and the connect could continue.
This approach works for more cases (like a MM crash and restart
while the modem is connected).
Initialized "cgmi_retries" variable from CustomInitContext with the
same value as the other retries, moreover the context is now allocated
with g_slice_new0.
Before this changes, when cgmi_retries assumed big values during the
probing of no AT-capable ports, the command AT+CGMI (mm-plugin-dell.c:custom_init_step)
was sent a semi-infinite number of times, blocking the plugin's initialization.
We try to combine in common envvars the compiler and linker flags shared by the
different components, and where possible, also re-using the implicit AM_CFLAGS
and AM_LDFLAGS variables that automake provides, and which apply to all objects
being built in the same Makefile.am.
The plugins build rules are also updated so that whenever a plugin has some
testable 'helpers', these are compiled into a noinst library and then the new
library included by both the plugin and the tester program. This avoids multiple
recompilations of the same sources for different objects.

The internal libmodem-helpers.la library is also renamed to libhelpers.la
For non-QMI/non-MBIM Huawei devices that use HiSense chipsets,
the recommended way to create the connection is to use NDISDUP
and either DHCP on the net interface, or the ^DHCP command.
There are some reports of devices that connect successfully, but
don't respond to DHCP requests on the interface. Try to get
IP addressing info from the device via ^DHCP and fall back to
telling clients to use actual DHCP if that fails.

Probe the Thuraya XT modem by USB vendor ID; there are no RS232 versions
to my knowledge.
One of my computers exhibiting the probing issue (VID/PID of the PCI
host controller instead of the USB device) fixed itself after a reboot.

Since GLib 2.42, the sockets that are added to socket listeners may no longer
be closed automatically when the listener is finalized. In order to avoid that,
we will keep our own socket reference and close/unref it ourselves.
This issue was preventing adding new test cases with the same port names.

We were wrongly using a main loop in the port context thread to manage the
global main context. That was silently making the DBus property notifications
kind of work, as they were being updated via another thread, so here we could
just sleep() and recheck the property values.
Given that having that unrelated thread updating the dbus properties of our
MMManager object is not a good thing, we'll instead totally ignore that and
fully re-create the MMManager in each iteration with the sync() method, which
has its own internal thread.
Instead of creating a new main context to be used in the thread, we were using
the global context. So, fix that, and create a totally new pair of main context
and main loop to be used within the thread.
We were trying to load the generic modes supported reported by either *CNTI=2 or
AT+WS46=?, so that then we could filter out the MBM-specific modes unsupported.
But, this may not be ideal, as both these two commands may fail:

Instead, we'll ask the modem for the list of modes supported, and return that
directly.
