Adds a new way to initialize the context, `ContextOptions`, and a new way to open devices, `OpenDeviceWithFileDescriptor`.
Combined they can be used to support Android devices, where device enumeration is not supported (can be now disabled through `ContextOptions`) and where USB devices can be opened in the Android SDK and passed over to gousb through a file descriptor.

* Add an invalid interface descriptor to one of the test devices.
* Add a test for getting that interface description.
* Handle the malformed interface/alternate setting descriptors, where
interface/alt numbers don't follow the spec (not 0-based, not contiguous
etc.)
Addresses issue #65.
* Add APIs for config and interface descriptors. Split out the common
parts of selecting a config descriptor from device desc and
selecting a setting descriptor from a config desc.
* Parallelize the few tests that actually can be parallelized safely.
Add comments where they can't. Note to self: it would be beneficial
to restructure the fakelibusb to index all properties of the lib
with the used context. That way a libusb implementation wouldn't need
to be referred via a shared variable.
