Otherwise it could still be connected when the port was opened again,
and subsequent calls for stuff could fail.

Previously, a few operations (like disable) could trigger a modem
flash in parallel with another flash. That's wrong, don't allow
that. At the same time, add in finer-grained error checking on
serial port speed operations, and fix a GSM generic bug that would
send the POWER_UP string on disable.

fix device removal event handling to remove modems
if the associated parent usb device is removed
|

Specifically, SupportedModes, SupportedBands, and SMS completeness changes.
|
|
|
|
Use the same enum for set/get of band and mode, as for exposing the
device's capabilities.

Sierra 580 returns "+CSS: 0, Z , 0" when not associated. Handle that.

Like the Sanyo SCP-3800 (Sprint Katana LX). Make up your freakin'
mind people, either prefix *all* responses with the command stem,
or don't. But just pick one dammit.

So many modems just don't implement carrier detect that it makes
the previous 'connected' logic useless, so base it off connect/disconnect
and fix up a few places that didn't check connect status before
trying to send commands. Also ensure the serial port is unlocked
for PPP to use when connected.

ZTE modems need to use udev rules to assign port type hints,
so generalize that and port all the plugins over to suggested
port types in the MMModem interface's grab_port() function.

It helps make the supports/grab callchain less crappy to look at
in gdb by ensuring that the supports chain unwinds before the grab
happens, and also ensures that we use the right subsys/name variables
rather than depending on ones the plugin provided to supports_callback,
that may go be freed by the plugin somewhere in grab_port().

Don't mis-use udev's ID_BUS key.

Allow plugins to perform asynchronous port detection, and to defer port detection
until later. This moves the prober bits into MMPluginBase so that all plugins
can take adavantage of it only when needed; the probing is not done at udev time.
Furthermore, plugins like Novatel can flip the secondary ports over the AT mode
through deferred detection, by deferring the secondary ports until the main port
has been detected and AT$NWDMAT has been sent.
This commit also finishes the port of the rest of the plugins (except mbm) over
to the new port detection methods and plugin API.

Otherwise, if something else is mistakenly holding the serial port open at
the same time as this MMSerialPort, you get a stream of reads of size 0 and
effectively hang modem-manager.

We'll need it in more than one place, so make it generic.
|

Create a base MMPort class to handle both tty and net ports generically,
and move plugins over to that. Also port the 'hso' plugin to udev.

It's generic, everything implements some variant of +GMM, +GMR, and +GMI.

Get rid of dependency on HAL, using libgudev instead. Fix up the plugin API
to no longer use either HAL or udev defines, but let plugins use whatever
mechanism they want for getting more information out of the device given the
subsystem and device node name.
Modems are now defined as "master" devices which "own" a one or more ports.
A port could be a serial tty device or a network device or whatever. The
plugin figures out whether it supports a given port or not and then assigns
it to a new or existing modem. Modems now have a 'valid' property that
should be set to TRUE when the modem has enough ports to operate correctly.
For devices (ex. 'hso') that use a network device for data transfer, the
modem would need to grab at least one TTY and the network device associated
with that physical device to be 'valid'.
Also move the generic modem support code to a plugin like other modem plugins,
and change the I-support-this-device mechanism to return a number indicating
the level of support. For example, the generic plugin would return a quite
low number if the device indicates via probing that it can do GSM or CDMA, but
a more specific plugin can indicate better support for the device, and thus
the more specific plugin would win control.

Add specific modes for HSUPA and HSPA; add modes for 2G and 3G only, and
update plugins to use the right modes.
