Currently, the search panel looks for search providers in
DATADIR/gnome-shell/search-providers. This won't work when providers are
located in a different directory which is still part of XDG_DATA_DIRS,
which is a valid use case and supported by gnome-shell.
This commit refactors the loader code to scan all the directories
upfront in a separate thread.

Search providers that should be disabled by default come with
a DefaultDisabled=true key in their keyfile, and are enabled
with the "enabled" whitelist, not with the "disabled" blacklist.

This is deprecated in newer automake versions, and this causes warnings
with automake 1.14:
panels/printers/Makefile.am:3: warning: 'INCLUDES' is the old name for
AM_CPPFLAGS' (or '*_CPPFLAGS')

Search providers can either have an explicitly configured sort order,
or be in the default alphabetical order based on their name.
Previously, when moving we would always assume that all providers had
a sort order, so moving an unsorted provider would put at the top.
The right thing to do, instead, is to walk the list in visual order
and assign an appropriate sort order, that is then flushed to gsettings.

Previously, we kept the last panel in the configured order last,
after non configured ones.This would assign a sort order to the last
panle that would place it in the middle, but visually sort it last,
and that caused problems when moving it (it would jump into an apparently
random position in the middle, according to the sort ID, and would
move the nearby provider too).

Very few of the panel comments provide information that is very
useful. Update them to supplement the panel descriptions - this
will make the search results more helpful.

Make it possible for panels to go all the way to the edge of the
shell. This is particularly important for panels that scroll, such
as the new power panel. All other panels are changed to compensate
for the loss of external padding.

This makes loading faster, with less I/O, avoids unnecessary
code duplication (around 1k lines shaved), and ensures that
all the panels link and work appropriately.
By the same token, it will stop external panels from being
created, and loaded.

Instead of either hard-depending on Tracker being installed, or crashing
when the Tracker GSettings schema is not found, make the configuration
insensitive if the schema is not available.
