Fixes NB#299221.

This fixes infinite recursion when indexing an out-of-config-trees file
(eg. via tracker-control -f <file>), as the miner aditionally indexes the
parent folders up to file:///, when reaching that case stale URN cache data
was making the miner think that the root folder hadn't been indexed yet.

This behavior is analogous to 0.10. The miner has to allow lesser
errors and insert minimal sparql for the files, but this kind of
errors must not trigger sparql insertion.

The accounting of currently processed files has been also improved, all
to ensure extractor_process_failsafe() is called just once, and tasks
waiting for process_file_cb() don't sneak in and break failsafe
extraction.

	src/miners/fs/tracker-miner-files.c

This method is independent of how the extractor works, unlike the
previous method. Now on a extractor failure, the miner does:

1) Pause itself
2) Wait for all pending extractor requests to finish
3) Accumulate all failed extractions on a list
4) Run through that list items, extracting again one file at a time.
5) Resume itself

	src/miners/fs/tracker-miner-files.c

Currently the simplest approach of retrying just once
every failed file is taken, after that, the sparql without
embedded metadata is added.

This is to be able to disable the files, applications or userguides miner from
actually starting. Starting here, means crawling/monitoring/indexing. The
miners are still established via D-Bus.

The ABS() where this field was used in had a calculation that could
result in a negative value within the ABS's brackets. Because it's
unrealistic that we'd ever need the value of this field to be larger
than int, we decided to just change it to signed int.

Fixes NB#290165.

This is only in 0.10 which is why this is needed

The finalizer of GDBusProxy schedules an idle function to disconnect
the name owner changed signal. This leaks a GMainContext if the
corresponding loop was already terminated.

Fixes NB#285426.

Both functions are available in upstream bindings.

This was fixed upstream in Vala 0.12.0.

DGifOpenFileHandle takes ownership on the FD, so don't try
to close it ourselves too.

TIFFdOpen() takes ownership on the FD, so do not try to close
it ourselves too.

tracker_read_text_from_fd() already takes care of closing it.

This is for cases where the locale specified has no userguide.

Fixes 2 bugs related to "Updating Library" showing for too long.

Fixes NB#285537.
Fixes NB#291569.

If not the current locale, we ignore the userguide directory, but only
when we HAVE_MEEGOTOUCH.
