To existing <bus>:<port>,<port> format add <bus>-<port>.<port> support.
The last format is used by kernel and other drivers.

Currently if ftdi device is removed, OpenOCD will stall forever.
Only kill -9 will help in this case.
This patch makes use of libusb timeout functions and
trying to break out of while loop if some error is detected.

The function libusb_get_port_numbers(), required for the command
ftdi_location, is only available in recent version of libusb1.
Compilation will break if the function is not available. This patch
enables the command only if libusb1 contains the necessary function.

This patch adds a 'ftdi_location' command to select an adapter by usb
bus number and port path.
This is helpful if you have a rack full of adapters in a testing or
manufacturing setup where the only constant is the physical usb bus
location of the adapter you want to address. Vid:Pid are not unique,
serial number _may_ be unique (and maybe not with embedded adapters) but
will change when a new target is plugged.
Specifying a location allows to understand instantly which board failed
bringup or testing.

An alternative approach to show how much cleaner the pure pkg-config
way is.
This changes the discovery procedures for libusb-1.0 and libusb-0.1,
making them depend on pkg-config being properly installed and
configured, including the necessary build host configuration for the
cross-builds (see
http://www.flameeyes.eu/autotools-mythbuster/pkgconfig/cross-compiling.html)
It should make it possible to compile OpenOCD without changes and
extra effort on GNU/Linux, FreeBSD users would need to supply a .pc
file for their libusb implementation or add LIBUSB1_LIBS and
LIBUSB1_CFLAGS to the configure environment.

Simplify the API by making all MPSSE command functions return void instead
of an error code. If there is an error during an implicit flush in a
command call, further commands are ignored until an explicit flush is
performed. The flush function returns and clears any error code set.
The only command functions that still return an error code are those that
can fail directly based on the type of the FTDI chip, i.e. when trying to
enable RCLK or divide-by-5 on a non-high-speed chip.
Adapt the ftdi adapter driver to the new API.

Print a user-friendly message when libusb_open() fails, e.g.
Error: libusb_open() failed with LIBUSB_ERROR_ACCESS
when there's a permissions problem.
Also output a configure warning if libusb older than 1.0.9 is detected.

When the ftdi driver calls finally the mpsse_flush function, it first
initiate the USB in and finally the corresponding USB out transaction.
Because data in is requested too early the USB device will always answer
the first USB in by a NAK. That can prevented by a simple reordering of
the out and then the in transfer and can improve the Jtag performance for
high JTAG clock rates.

This is a higher-level libftdi replacement for use when implementing
protocol drivers for FT2232, FT2232H or FT4232H. It takes care of device
open/close and, unlike libftdi, also MPSSE command abstraction, command
queueing, buffer handling and return data parsing.
The FTDI device is accessed through libusb-1.0 in asynchronous mode.
