- stlink_usb_get_rw_status() had a bug where FAULT or WAIT responses
in read/write operations were ignored, leading to incomplete data.
- Added wrapper stlink_cmd_allow_retry to handle
SWD_AP_WAIT/SWD_DP_WAIT statuses in most commands. These statuses
appear if an SWD read or write received a WAIT ACK response from the
target more than 4 times in a row. The driver retries the operation
(with exponential backoff) before failing outright (in testing 1
retry was always enough.)
- As part of the implementation of stlink_cmd_allow_retry a large
number of lines of boilerplate were refactored.
- Fleshed out stlink_usb_error_check and added it to some more code
paths so WAIT or FAULT responses are logged to debug. WAIT responses
will be logged even if they are subsequently retried, which should
help in case the retries have subtle side effects (none
anticipated.)
Tested with two targets: STLINK F0 Discovery, Nordic NRF51822. Only
tested with STLINK V2 programmers.

This is usable on most or all FTDI adapters using a small hardware tweak.
TCK goes to SWCLK as expected. TDO should be wired to SWDIO. For TDI there
are two options:
Either add a 74HC126 or similar tri-state buffer between TDI and SWDIO,
with OE controlled by a signal named SWDIO_OE. Or simply connect TDI and
SWDIO together via a suitable resistor (220-470 ohms or so depending on
the drive capability of the target and adapter).
nSRST (and of course Vcc, GND) may be connected too but all other signals
should be NC.

The JLink-OB (onboard) devices work the same way as the normal JLink
except that their PID is 0x0105 (and that's the only one we know of so
far) and their endpoint addresses are different due to there being a
CDC-ACM interface as well. These JLink-OB devices show up on a lot of
vendors' development kits as an integrated debugger.
This change simply checks whether the adapter we opened has a JLink-OB
PID and, if it does, uses the JLink-OB endpoints rather than the
default. To do this, we add a new routine, jtag_libusb_get_pid() to the
libusb adapter layer, it in turn just calls
libusb_get_device_descriptor(), which previously had no wrapper.
Also, checkpatch.pl doesn't like the VID/PID macros as defined so I
moved them to the array itself. This should have no effect on the code.
This change adds the 0102 through 0104 PIDs to openocd.rules as well as this
new 0105 PID.
Tested on an Atmel SAM4S Xplained board which has a JLink-OB, also
regression tested by using a 0x0101 PID normal JLink adapter.

The existing CMSIS-DAP driver matches the USB VID/PID against 0x3eb
(Atmel VID) and 0x2111 (Atmel EDBG embedded CMSIS-DAP debugger), and
then bumps the packet size from its default of 64 to 512. However, it
turned out that *all* Atmel-provided CMSIS-DAP devices (EDBG with PID
0x2111; JTAGICE3 with firmware version 3.x, PID 0x2140; new Atmel-ICE
[successor of JTAGICE3], PID 0x2141) require a 512-byte packet size.
Obviously, all run the same USB implementation inside their custom
microcontroller. Thus, it seems best to simply assume that *all*
Atmel CMSIS-DAP devices use this packet size, and don't check the PID
at all.

while (usually) all devices can be traversed, devices the user does
not have permission for cannot be read the product string from,
resulting in a NULL pointer. Trying to find the substring "CMSIS-DAP"
causes a segementation fault then.

The ST-LINK/V2 has limited internal buffering, such that trace data
can be missed if the target is generating data at a rate quicker than
the OpenOCD trace sampling. The issue of lost data is compounded since
individual TPIU packets may be split across individual STLINK_TRACE_EP
reads, and misleading results can occur if mid-packet loss occurs.
This patch increases the frequency of checking for pending trace data
with the aim of minimising such losses. Note: With the limited (I/O
and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a
guarantee against trace data loss.
The timer callback is only added when enabling tracing, and is removed
when tracing is disabled.
