c1009ed25d Call back to Go function directly, it will know how to deal with an xfer 
pointer.

550fe8d1f2 Introduce xferMap, avoid passing Go pointer into the C code. 
Weirdness with memory barriers.

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.

56162d0105 Remove BCD.Int, add BCD.Major/Minor. Remove USB spec versions 
- I don't expect them to get much use, and reuse of BCD for USB spec
version and device revision makes it somewhat confusing.

13f4e95f2f Unexport bitmasks, they are only used internally. All values present 
in exported structs are meaningful and the users should not need to use
bitmasks.

3ec748db4c An invalid pointer triggers a runtime failure when passed as argument in 
Go1.7:
runtime: bad pointer in frame
github.com/kylelemons/gousb/usb.(*fakeLibusb).open at 0xc420045ce0: 0x1
fatal error: invalid stack pointer

Use an arbitrary C-allocated pointer instead.

e0f30623b3 Modify EndpointInfo to provide meaningful data rather than raw USB 
descriptor values. E.g. for the user, the distinction between
MaxIsoPkt and MaxPktSize is irrelevant, only the calculated max packet
size matters.

Sebastian Zagrodzki
1f977a94aa Update the comment - there's no way to create a new pointer to struct 
libusb_device, since the struct is not defined in libusb headers (only
name is declared), as such the compiler doesn't know the size of the
struct to allocate.
