Android 5.0 uses service name (sic!) for defining instance ID and
supported message types. Name passed is in format of "XXYYname"
where XX is hex coded instance and YY is hex coded message types
mask.
This patch adds new mode for Socket HAL in which daemon tries to
extract instance ID and message types from service name.
