Remove libusbx.

This was a fork of libusb1, but as of libusb1-1.0.18 they are merged
again, and pkgsrc now contains 1.0.19.

Log message:
document NOT_FOR_PLATFORM

Log message:
(from pkglint)
The update request to 1.0.18 from doc/TODO ([but actually obsolete,
switch to libusb]) has been done.

(upstream)
  Update 1.0.11 to 1.0.18
For detailed information about the changes below, please see the git log or
visit: http://log.libusbx.org

2014-01-25: v1.0.18 *FINAL RELEASE*
* Last release of libusbx, as the project is merging back again with libusb.
  As a result, continuation of the project will now occur from the following:
  o Main site:          http://libusb.info
  o Git repository:     https://github.com/libusb/libusb
  o SF repository:      https://sourceforge.net/projects/libusb/
  o Mailing list:       libusb-devel@lists.sourceforge.net (registration req.)
* Fix multiple memory leaks
* Fix a crash when HID transfers return no data on Windows
* Ensure all pending events are consumed
* Improve Android and ucLinux support
* Multiple Windows improvements (error logging, VS2013, VIA xHCI support)
* Multiple OS X improvements (broken compilation, SIGFPE, 64bit support)

2013-09-06: v1.0.17
* Hotplug callbacks now always get passed a libusb_context, even if it is
  the default context. Previously NULL would be passed for the default context,
  but since the first context created is the default context, and most apps
  use only 1 context, this meant that apps explicitly creating a context would
  still get passed NULL
* Android: Add .mk files to build with the Android NDK
* Darwin: Add Xcode project
* Darwin: Fix crash on unplug (#121)
* Linux: Fix hang (deadlock) on libusb_exit
* Linux: Fix libusbx build failure with --disable-udev (#124)
* Linux: Fix libusb_get_device_list() hang with --disable-udev (#130)
* OpenBSD: Update OpenBSD backend with support for control transfers to
  non-ugen(4) devices and make get_configuration() no longer generate I/O.
  Note that using this libusbx version on OpenBSD requires using
  OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised
  to stay with the libusb shipped with OpenBSD (mpi)
* Windows: fix libusb_dll_2010.vcxproj link errors (#129)
* Various other bug fixes and improvements
The (#xx) numbers are libusbx issue numbers, see ie:
https://github.com/libusbx/libusbx/issues/121

2013-07-11: v1.0.16
* Add hotplug support for Darwin and Linux (#9)
* Add superspeed endpoint companion descriptor support (#15)
* Add BOS descriptor support (#15)
* Make descriptor parsing code more robust
* New libusb_get_port_numbers API, this is libusb_get_port_path without
  the unnecessary context parameter, libusb_get_port_path is now deprecated
* New libusb_strerror API (#14)
* New libusb_set_auto_detach_kernel_driver API (#17)
* Improve topology API docs (#95)
* Logging now use a single write call per log-message, avoiding log-message
  "interlacing" when using multiple threads.
* Android: use Android logging when building on Android (#101)
* Darwin: make libusb_reset reenumerate device on descriptors change (#89)
* Darwin: add support for the LIBUSB_TRANSFER_ADD_ZERO_PACKET flag (#91)
* Darwin: add a device cache (#112, #114)
* Examples: Add sam3u_benchmark isochronous example by Harald Welte (#109)
* Many other bug fixes and improvements
The (#xx) numbers are libusbx issue numbers, see ie:
https://github.com/libusbx/libusbx/issues/9

2013-04-15: v1.0.15
* Improve transfer cancellation and avoid short read failures on broken descriptors
* Filter out 8-bit characters in libusb_get_string_descriptor_ascii()
* Add WinCE support
* Add library stress tests
* Add Cypress FX3 firmware upload support for fxload sample
* Add HID and kernel driver detach support capabilities detection
* Add SuperSpeed detection on OS X
* Fix bInterval value interpretation on OS X
* Fix issues with autoclaim, composite HID devices, interface autoclaim and
  early abort in libusb_close() on Windows. Also add VS2012 solution files.
* Improve fd event handling on Linux
* Other bug fixes and improvements

2012-09-26: v1.0.14
* Reverts the previous API change with regards to bMaxPower.
  If this doesn't matter to you, you are encouraged to keep using v1.0.13,
  as it will use the same attribute as v2.0, to be released soon.
* Note that LIBUSBX_API_VERSION is *decreased* to 0x010000FF and the previous
  guidelines with regards to concurrent use of MaxPower/bMaxPower still apply.

2012-09-20: v1.0.13
* [MAJOR] Fix a typo in the API with struct libusb_config_descriptor where
  MaxPower was used instead of bMaxPower, as defined in the specs. If your
  application was accessing the MaxPower attribute, and you need to maintain
  compatibility with libusb or older versions, see APPENDIX A below.
* Fix broken support for the 0.1 -> 1.0 libusb-compat layer
* Fix unwanted cancellation of pending timeouts as well as major timeout related bugs
* Fix handling of HID and composite devices on Windows
* Introduce LIBUSBX_API_VERSION macro
* Add Cypress FX/FX2 firmware upload sample, based on fxload from
  http://linux-hotplug.sourceforge.net
* Add libusb0 (libusb-win32) and libusbK driver support on Windows. Note that while
  the drivers allow it, isochronous transfers are not supported yet in libusbx. Also
  not supported yet is the use of libusb-win32 filter drivers on composite interfaces
* Add support for the new get_capabilities ioctl on Linux and avoid unnecessary
  splitting of bulk transfers
* Improve support for newer Intel and Renesas USB 3.0 controllers on Windows
* Harmonize the device number for root hubs across platforms
* Other bug fixes and improvements

2012-06-15: v1.0.12
* Fix a potential major regression with pthread on Linux
* Fix missing thread ID from debug log output on cygwin
* Fix possible crash when using longjmp and MinGW's gcc 4.6
* Add topology calls: libusb_get_port_number(), libusb_get_parent() & \ 
libusb_get_port_path()
* Add toggleable debug, using libusb_set_debug() or the LIBUSB_DEBUG environment \ 
variable
* Define log levels in libusb.h and set timestamp origin to first libusb_init() call
* All logging is now sent to to stderr (info was sent to stdout previously)
* Update log messages severity and avoid polluting log output on OS-X
* Add HID driver support on Windows
* Enable interchangeability of MSVC and MinGW DLLs
* Additional bug fixes and improvements

devel/libusbx: Mark NOT-FOR-DRAGONFLY

The library has to be specifically and non-trivially ported to each
platform it supports and currently it is not ported to DragonFly.
Moveover, FreeBSD's USB stack, which uses the same API, is intended to
ported to DragonFly in the near future.

Log message:
Add buildlink3.mk.

Log message:
Initial import of libusbx, a fork of libusb1.

libusbx is a library that provides generic access to USB devices.
As a library, it is meant to be used by developers, to facilitate
the development of applications that communicate with USB hardware.

It is portable: Using a single cross-platform API, it provides
access to USB devices on Linux, OS X, Windows and OpenBSD.

It is user-mode: No special privilege or elevation is required for
the application to communicate with a device.

It is version-agnostic: All versions of the USB protocol, from 1.0
to 3.0 (latest), are supported.

libusbx is a fork of libusb.
