Replace direct logic in support for 'adb remount' with an exec out to
/system/bin/remount to do the heavy lifting. Remount success and
failure strings are reported by the adb remount service in response
to the various reported errors, freeing up the remount command itself
from the legacy of script expectations.
Test: adb-remount-test.sh

Preparatory step for testing adb on GCE on non-linux hosts: instead of
pointing them at a device (emulated or otherwise), point them at adbd
running on a linux host instead.
Test: adbd & adb connect localhost:5555; adb -e wait-for-device shell

Replace all usages of android::base::unique_fd with the unique_fd from
adb_unique_fd.h, which calls adb_close instead of close on Windows.
Most of these changes are no-ops, except for the ones to
create_service_thread, which was probably pretty broken on Windows.
Test: python test_device.py
Test: adb_test
Test: wine adb_test.exe
