devtool: sdk-update: improve SDK update process robustness

Browse Source 
Make the following improvements to the SDK update process:

* Use a manifest file with sha256sums to track files other than sstate
  and metadata that we need to update - e.g. conf files. This allows us
  to handle where files such as auto.conf may or may not be present,
  as well as the configuration changing without affecting task signatures
  - we still want the config files copied in that case rather than it
  saying nothing needs to be done.
* Write the SSTATE_MIRRORS_append to site.conf rather than local.conf
  so that local.conf remains static (since we don't want to trigger an
  update every time). Also, If there is an SSTATE_MIRRORS value already
  set in the configuration we can skip this and assume it contains the
  needed packages.
* Allow the update process to be run in any directory, don't assume
  we're already at the base of the SDK
* Where practical, fetch remote files into a temporary location and
  then move them to the desired location at the end, to avoid a
  failed update leaving the SDK in a broken state.
* Update all installed do_populate_sysroot / do_packagedata tasks
  instead of using the SDK targets. This ensures any item installed
  through dependencies after installation (e.g. when running
  "devtool build") won't go stale.
