Add the ID_MM_MAX_TIMEOUTS udev tag to allow users and system
administrators to configure the maximum number of consecutive
command timeouts before a modem is invalidated and re-probed,
on a per-device basis.
The tag accepts an integer value >= 0, where 0 disables the
timeout monitoring feature entirely. If not set, the existing
default of 10 consecutive timeouts is used.
This is needed for some older modems which become unresponsive
during consecutive data traffic, but come back alive when traffic
is lower. These modems have no further firmware updates available.
This follows the same pattern as other udev-configurable device
properties like ID_MM_MAX_MULTIPLEXED_LINKS.
