These diagrams are not expected to change much, so just include the generated
PNGs in the repository, and remove 'dia' from the prerequisites to build the
documentation.
We cannot g_array_unref() the GArray when get()-ing bands as that will clear
the contents of the GArray, even if there are references around. Instead, just
dup the array contents when returning.
This patch fixes the following invalid comparison of unsigned expression:
novatel/mm-plugin-novatel.c:148:29: error: comparison of unsigned
expression >= 0 is always true [-Werror,-Wtautological-compare]

Some QMI modems seem to fail when requesting to list all SMS messages in a given
storage. When this happens, we'll loop through all storages but performing per
tag list requests.
If the bearer is connected and we get a notification of being unregistered, wait
up to 15s to force the disconnection, in case we can recover the registration
in the meantime.

Newer Huawei modems, like the E3276 or the ME906 won't support ^SYSINFO, and we
should instead use the newer ^SYSINFOEX. By default, use ^SYSINFOEX when
available, as it provides more information than the plain ^SYSINFO.
E.g.:
^SYSINFOEX:2,3,0,1,,3,"WCDMA",41,"HSPA+"
^SYSINFOEX:2,3,1,1,1,3,”WCDMA”,46,”DC-HSPA+”
These messages give us information about the current connection status in the
NDIS interface. We already have other means to know this status, so we just
ignore the unsolicited message for now.
E.g.:
^NDISSTAT: 1,,,"IPV4"
Newer Huawei modems use ^HCSQ to report per-interface signal quality values,
but we don't know yet what each field means for each technology, so just ignore
them for now.
E.g.:
^HCSQ: "GSM", 53
^HCSQ: "WCDMA", 26, 24, 43
^HCSQ: "LTE", 40, 28, 216, 14
We also don't use this message to update current access technology information,
as it is not detailed enough (e.g. WCDMA doesn't specify whether it's plain UMTS
or HSDPA or HSPA+...)
We filter the E362 because it's managed by the Novatel LTE plugin. If we also
filter out the USB551L, but it's not explicitly grabbed by any other plugin, it
will default to the Generic one.
CDMA-only devices don't support +ZPAS for access tech loading, so chain up to the
parent so we get the QCDM fallback access tech loading functions.

During init, the N900 appears to ignore an E0 in the same command as
an E1. So just add another init command to disable echo, which won't
have any effect on devices that work with the first command.
This patch removes an unnecessary check of unsigned expression >= 0,
which also fixes the following clang warnings:
sierra/mm-broadband-modem-sierra.c:570:18: error: comparison of
unsigned expression >= 0 is always true
[-Werror,-Wtautological-compare]
mode >= 0 &&

Patched by Yunlian Jiang <yunlian@chromium.org>
A value 0 is used to denote an invalid/uninitialized CID. This patch
fixes a CID check in disconnect_3gpp() of MMBroadbandBearer such that it
disables all PDP contexts via AT+CGACT=0 when no specific CID is used
(i.e. cid == 0).
This patch updates normalize_ciev_cind_signal_quality() in
MMBroadbandModem to remove an unnecessary check on 'quality >= 0' and
also makes sure the normalized signal quality is capped at 100 when no
maximum is specified.
This is revised from a patch originally authored by
Yunlian Jiang <yunlian@chromium.org>.

For some reason a number of ZTE CDMA devices want the whole QCDM
frame in one USB transaction, or at least don't like it being
broken up and sent byte-by-byte with a send delay. They simply
don't respond. Since testing indicates that every other QCDM
capable device I've got also handles a zero send delay on both
3.8.8 and 2.6.32, lets just set it to zero for everything,
which should speed things up a bit too.

The GetNetworkTime() response is defined to be an ISO8601 string, which
is in turn defined to be in local time. Make sure that's reflected in
the documentation, and append the timezone offset to UTC where we have
it.
Oddly, Icera devices return their time info in UTC with an offset to
the local timezone, so we have to jump through some hoops there to
convert the response to localtime based on the reported offset.

If no capabilities could be determined from the modem's responses,
result would be NULL but no error would be set, since the modem
didn't time out or have some other critical error, it simply didn't
report any recognized capabilities. Ensure that an error is
reported in this case.

Icera devices include bands that the modem doesn't support in
the %IPBM=? list, so the plugin sets the band to its current
enabled/disabled value to test whether that band is supported.
There were two problems with this approach:
1) Setting an already-enabled band to be enabled apparently
isn't a NOP; it might take more than the 3 seconds given, and
if the response comes after 3 seconds, this greatly confuses
ModemManager because the AT command/reply sequence is now
messed up. So increase the timeout to 10 seconds.
2) Why bother checking bands that are already enabled anyway?
We already know they are supported, so just don't check those
bands at all. This requires some parkour because we use the
parsed band array from %IPBM=? to track whether bands are
enabled/disabled by indexing into the array, so instead just
use two separate arrays. This actually makes the fix for #1
un-needed (because we never enable any bands) but it's good
to have #1 anyway.
You can't g_array_insert_val() to an index that's beyond the end
of the array, which was happening if the user tried to set the
band list to "any":
mmcli -m 0 --set-bands=any
Just use g_array_append_val() instead.

The USB305 (Icera-based) apparently has a port that replies to everything
with ERROR, and that port is unusable. Make sure it's ignored, otherwise
MM may claim it as the primary AT port since it technically speaks AT.
This patch removes a few unnecessary NULL checks on free(), which also fixes
the following clang warnings:
result.c:59:27: error: if statement has empty body [-Werror,-Wempty-body]
if (v->u.u8_array);
^
result.c:59:27: note: put the semicolon on a separate line to silence this warning
