T2U-3.0:Give much useful information for t2u app
A new duplicate for t2u_allow variable is created.
which is ensured to be kept true when the phone is unlocked by t2u(screen off)
other wise 'false' . As the t2u_allow variable which is used to force touch suspend and resume
cannot give the actual information like how the phone is unlocked which is required
for v0.6 of the t2u app for the proper working (without any security vulnerability)
and proper functioning , avoiding any freezes during unexpected time.

Also call all the commits after t2u 2.0 as t2u 3.0
