This introduces a new common function that allows auto-discovery of a
suitable USB interface based on class, subclass and protocol
matching. It claims the interface and returns the corresponding
endpoints number to the caller.
The need for this arised due to nRF51822 USB dongle which comes with
an "on-board Segger J-link debugger" having 3 interfaces, so the
current code can't work at all with it (in this particular case the
last interface needs to be choosen). This also removes special
handling of JLink-OB endpoint numbers as it's now possible to
autodetect them as well as the standard JLink endpoints.

at91samd: fix protect, add EEPROM and boot commands
There were two problems with the _protect() feature:
1. The address written was off by a factor of two because the address
register takes 16-bit rather than 8-bit addresses. As a result the
wrong sectors were (un)protected with the protect command. This has
been fixed.
2. The protection settings issued via the lock or unlock region commands
don't persist after reset. Making them persist requires modifying the
LOCK bits in the User Row using the infrastructure described below.
The Atmel SAMD2x MCUs provide a User Row (the size of which is one
page). This contains a few settings that users may wish to modify from
the debugger, especially during production. This change adds commands
to inspect and set:
- EEPROM size, the size in bytes of the emulated EEPROM region of the
Flash.
- Bootloader size, the size in bytes of the protected "boot" section of
the Flash.
This is done by a careful read-modify-write of the special User Row
page, avoiding erasing when possible and disallowing the changing of
documented reserved bits. The Atmel SAMD20 datasheet was used for bit
positions and descriptions, size tables, etc. and testing was done on a
SAMD20 Xplained Pro board.
It's technically possible to store arbitrary user data (ex: serial
numbers, MAC addresses, etc) in the remaining portion of the User Row
page (that is, beyond the first 64 bits of it). The infrastructure used
by the eeprom and bootloader commands can be used to access this as
well, and this seems safer than exposing the User Row as a normal Flash
sector that openocd understands due to the delicate nature of some of
the data stored there.

jtag: always configure enabled tap parameter appropriately
Commit f701c0cb seems to have introduced a regression for non-JTAG
transports as the newly created "tap" (DAP actually) ended up being
disabled, thus resulting in total lack of functionality.
This was exposed by a debug log demonstrating ftdi SWD transport
connection to mdr32f9q2i, the target wasn't examined on init and
couldn't be reset.
This adds initial support for the STM32L0 family, specifically the ID
code 417 variant. The 'L0 has 128B rather than 256B pages as well as a
different number of pages per sector. It also has several key registers
and register sets in different locations from the STM32L1xx parts.
This change therefore takes the opportunity to reorganize part information into
a const table (it was previously determined by a set of control statements) and
abstracts away some of the low-level details to make them generic for L1 and
L0 parts.
We also include the first bank's size (for dual bank parts) in the new
device information table (and correct that size for the 0x437 variant
which is 256 rather than 192KB).
The 'L0 parts will not use the built-in loader/helper for Flash writing.

jtag: usb_blaster: fix initialization regression
As Daniel pointed out, since the rewrite of the USB Blaster driver, the
initialization behaviour has change. The initial flush of the FIFOs is
not longer done with a specific USB setup packet, but with a write
filling up the blaster queues.
The problem is, quoting Daniel :
When the CPLD is in bit banging mode (as is usually the case), the
first 0x00 byte sets all pins to low and disables the output
driver. Disabling the output drivers is a few nanoseconds slower
than changing a pin from high to low, so I see a spike towards GND
on my reset line when that byte is sent over USB. The spike is too
short to have an effect on the board.
When the 4096 0x00 bytes are processed and the TMS=1 is to be
generated, all I see is several microseconds of low level on all
pins, resetting my board.
This patch changes the way the initialization is done :
- at driver init, nothing is sent towards the usb-blaster
This gives time for init script to setup PIN6 and PIN8 (resets)
- at the very first driver command, the initialization is done :
- the output is in bit bigbang mode
- the PIN6 and PIN8 are computed according to init script
- the 4096 computed output is sent
