When my SNES30 controller was in bootloader mode, it wouldn't update,
and when it was in controller mode, it tried and failed. Now, it prints
out the instructions on how to reset the device if it's in controller
mode, and if it's in bootloader mode, it successfully installs the
firmware update from the .DAT file.
This allows us to binary patch firmware images.
The diff generation is implemented with a forwards-only algorithm; this allows
a vendor to remove non-free code without shipping a "reversed" version of the
non-redistributable code.
In this mode, both the metadata and firmware is stored on the local filesystem
and distributed using a distribution system like OSTree.

Calling g-ir-scanner when cross-compiling with bitbake/OpenEmbedded
fails because it calls the wrong ld (the one from the host). More work
will be needed in meson.bbclass and/or gobject-introspection.bbclass
to make it work.
In the meantime, having an option to turn of introspection is useful
perhaps also in other cases where the extra work is not needed. For
example, fwupd works fine also when it is off.
The name of the new meson option matches the --disable-introspection
that is used by some autotools-based projects.

Pre-filter the pending LuDeviceBootloaderRequest's after they are parsed so
that we know exactly how many packets need to be sent to the hardware.
As shown in https://github.com/hughsie/fwupd/issues/155, people get worried
if the progress bar finishes before 100% as they'll wonder if all the writing
completed successfully.
This avoids open()ing and close()ing multiple times on hotplug -- which in
itself isn't a huge problem as the requests are refcounted in libusb, but it
matters hugely when a plugin accidentally closes a device that was not opened.
As all the devices are going to be opened anyway (to read the vendor strings)
and the cost of keeping the device is open is tiny, just get libgusb to
auto-open *all* devices and keep them open for the duration.

When reading with g_dir_read_name() the returned files do not have to be sorted
in any particular order and could even change between invokation. This patch
makes debugging the interactions between plugins much easier.
