use date from 1970-01-01 to 2037-12-31 in DatePickerDialog

In case of using DatePickerDialog, user could select any date
before 1970-01-01. However, the system clock cannot be set to
a date before 1970-01-01.
As a result, user couldn't select date before 1970-01-01.
So, use date from 1970-01-01 to 2037-12-31 of DatePickerDialog.

Steps to reproduce:
1. Settings -> Date & time
2. uncheck Automatic date & time
3. Set Date
4. choose any date before 1970 and Done
