Patch to make APN comparison case insensitive.

Created attachment 109435 [details] Patch to make APN comparison case insensitive. According to see 3GPP TS 23.003 chapter 9.1, the APN name is case insensitive (thanks dcbw and roox for helping clarify this). ModemManager does not currently use a case-insensitive comparison when scanning the list provided from AT+CGDCONT? A new cut of modem firmware for a Sierra HL7, has a "feature" or bug that converts the all lowercase APN that was input to all uppercase when read back later. This causes ModemManager to use a new PDP context ID each time and exhaust the PDP CID slots after several connections. With a single line comparison change, this could be prevented and more closely follow the 3GPP spec. Patch for master branch attached. Please let me know if more description/clarification is needed.
