healthd: Disable the RTC wakeup timer

The timer is used here to avoid battery drained to zero. But the periodic
wakeup during suspend should not be needed as MSM PMIC already support
that by trigger interrupt to avoid the critical low battery situation.
This will save more power. And if the design is not support HW interrupt
of low battery, need to enable the timer to periodic check.

Revert "adbd: Don't close/reopen FFS ep0 on disconnect"

This reverts commit b5d385f1ef38ad0c163598c3a4e167d4ae9df3c6.

Commit b5d385f "adbd: Don't close/reopen FFS ep0 on disconnect"
fixes USBCV chapter 9 failures due to re-enumeration as part of
reopening FFS ep0 handle. This was done from usb_kick function
which gets invoked whenever adb read/write fails.
But, not allowing USB re-enumeration on real IO failures results
in adb to go offline and only way to recover is by re-connecting
USB cable.
As ADB function is used for debugging and USBCV tests are not
mandatory, hence, revert original change to allow USB
enumeration on any read/write failures.

Dedupe _GNU_SOURCE and ucontext.h definition and inclusion, put them in sane locations.
