List of things left for later:
----------------------------------------

 * qmi-codegen: Skip additional heap allocation for Strings marked with
   'max-size'. If the 'max-size' is short enough, we can just use arrays of
   gchars with a specific size directly in the input/output bundle.

 * qmi-codegen: support new `digit-string' format type

 * qmi-codegen: allow specifying max number of items expected in an array.

 * qmi-codegen: allow specifying a constant value, when a field only allows one.

 * qmi-codegen: allow specifying 'version' for TLVs, to indicate in which
   version of the service they were introduced, so that we return an error when
   trying to use those unsupported by our device.

 * qmi-codegen: allow specifying 'description' to both messages and TLVs.

 * qmi-codegen: some bitmask fields could have some more love. A new
   'bit-sequence' format type would allow us to have getters for specific bit
   values, and would also allow us to split a given set of flags into more
   detailed sub-types, e.g.: the 'QmiNasRadioTechnologyPreference' flags type,
   where the first two bits define the type of the next ones.

 * qmicli: Implement `--dms-set-time'.
 * qmicli: Implement `--dms-get-alt-net-config'.
 * qmicli: Implement `--dms-set-alt-net-config'.
 * qmicli: Implement `--dms-get-software-version'.
 * qmicli: Implement `--dms-set-service-programming-code'.

 * qmicli: Print 3GPP2 network description in "Get Home Network"

 * nas: Define the 'QmiNasRegistrationRejectCause' enum for the "Event Report"
   indication and "Get System Info" response.

 * pds: Parse all possible TLVs in the Event Report indications
