In the case where we can trigger the replug automatically we can have to wait
for a USB re-enumeration (typically a few hundred ms) but when the user is
requred to unplug, and then replug we have to wait a bit longer.
The 'remove delay' allows us to modify per-device the removal delay. In the
case the device does not show back up in the correct time the device will be
auto-removed and the session will get a DeviceRemoved signal. In the case where
the device in bootloader mode shows up within the timeout the session just gets
a DeviceChanged event.
For the duration of the delayed removal the flags for the device are set to
zero to ensure the session does not try to interact with the device whilst
re-enumerating.
This moves more functionality out of the engine, and will allow us to add some
cleverness to the device list to allow the FuDevice to be shared between
different plugins.
The ColorHug plugin was the very first plugin for fwupd, and it's not been
ported to use all the various helpers used in other USB plugins. It shows.
This gets rid of a lot of complexity and makes the plugin more reliable.
Kernel 4.15 adds support for Thunderbolt P2P devices via
CONFIG_THUNDERBOLT_NET. When turned on and activated fwupd will
show an empty device representing the IP connection between machines.
These device types aren't useful in fwupd and should be filtered.

Although we don't quite do the right thing, we only need to typically work out
the start offset of the firmware. This fixes 'dfu-tool dump foo.hex' for files
produced for the ATMEL ATXMEGA architechure.
Previously, the various install paths were obtained using get_option
as needed.
This patch unifies the directory selection inside the top-level meson
file as requested in https://github.com/hughsie/colord/pull/62.
This allows us to flash hardware like the Retrode and other devices using chips
like the AT90USB1287.
The test files can be re-generated using the sample code found here:
https://github.com/hughsie/fwupd-test-firmware and are designed
to be used on the AT90USBKEY2 development board.
This makes CI more useful as there is currently a problem with
gcab 0.7 and big endian architectures not yet fixed.

It's actually less scary to see a SHA1 hash than it is to see a path like
/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.2. It's also way easier to
copy and paste into the various fwupdmgr command that require a device ID and
also means we can match a partial prefix much like git allows.
If we also move to a model where plugins can be changed during different stages
of the update (e.g. during detach) then the device might change connection type
and then the sysfs path not only becomes difficult to paste, but incorrect.
Session software doesn't care about the format of the device ID (it is supposed
to be an implementation detail) and so there's no API or ABI break here. A few
plugins also needed to be ported, but nothing too worrying.
This allows end-users testing a specific plugin to start fwupd with an extra
command line parameter, e.g. `--plugin-verbose=unifying` to output a lot of
debugging information to the console for that specific plugin.
This replaces a lot of ad-hoc environment variables with different naming
conventions.
This allows us to do two things:
* Attach after a failed update, so the user isn't left with 'dead' hardware
* Split the detach and attach actions into different plugins in the future
This also allows us to have a separate vfunc to get the new version number
after flashing the firmware, as this may be handled in a different plugin to
the detach phase.
