6d81ca37d3 Use a map to store endpoint descriptors. Allows easy access to a 
particular endpoint number.

77c176cd4c Replace descriptor Configs with a map - config ids are arbitrary numbers 
(unlike interface or alt setting numbers, which are 0-based array indices).
This makes it easier to access a particular config without having to
iterate over the descriptors.

5f122b4dcd Introduce two more layers between device and endpoint: 
device -> active config -> claimed interface -> endpoints.
Device can have at most one active config. A config can have
multiple claimed interfaces, each with a specific alt setting.
An interface with an alt setting defines a list of endpoints.

9cecdec977 Fix a bug where EndpointInfo would always be picked from the last 
alternative setting.

When looking up matching EndpointInfo and InterfaceSetting for
an endpoint, a reference to range variable is stored. If range is
allowed to continue, the value of this variable will be updated.
It's a trick to allow use of "nil" pointer as a "found" variable, but it
requires a careful management of the range iterations.

b0d5519c67 Change the iso packet size if the buffer is very small. 
Previously number of iso packets could have amounted to a transfer
buffer larger than passed buffer, which could lead to overflow.

Now the number of bytes requested from device is always smaller or equal
to the buffer size.

In theory, it could lead to inefficiencies in transfer: if max packet
size is 1024 and user request 2046 bytes of data, transfer will return at most
1024 bytes, while it could use a more efficient 2 packets of 1023 bytes.
But at least it's correct now. It seems that for efficiency the user would
always use the reported max packet size anyway.

The device could still send more data than requested, but libusb takes
care of it.
