Connectivity: Set TCP delayed ACK and User Configuration Flag

Provide a Mechanism to set tcp delayed ack settings from
Connectivity Service. The tcp_use_userconfig flag is set to
override the default tcp delayed ack configuration in tcp stack.
tcp_use_userconfig flag is reset when the TCP stack is required
to use default delayed ack settings. Currently the delayed ack
settings are overridden for Wifi and LTE networks only. Other
network types continue to use default delayed ack settings

services: change default sampling interval to -1

Change default sampling interval to -1 to avoid sampling to resolve

UserTile: Fix displaying user information for multi-user devices

In commit 89ab0eb097322ac8eec40159b888dfb03b9413e9, we improved
the handling of single user devices but appear to have also
entirely deleted the name / avatar for multi-user devices.

This commit restores the deleted code for multi-user devices.

This fixes CYAN-4023.

CM11 Themes: Ensure customTheme is not null.

The configuration retrieved via getConfiguration() sometimes contains
a null customTheme which results in the theme returning to holo when
applying a component such as icons.  Icons will change but styles
and fonts would return to the default.
