The -T parameter only seems to limit the maximum time between received
packets, but not the overall run time.
This adds simple timeouts to the wget calls (5 minutes for the manifest,
30 minutes for the image). The implementation is very simple, only checking
the manifest timeout each time a line was received, and the image timeout
once a second. A more elegent fix seems like overkill, as the Lua
autoupdater will be replaced with a new implementation after Gluon 2016.2
anyways.
All executables in download.d are executed before after the update manifest
has been verified, but before the image is downloaded. This can be used to
stop non-essential services to free RAM.
abort.d is run when the download has failed and should revert the actions
of download.d.
