jtag: drivers: Add JTAP VPI client driver

This patch adds a driver for the jtag_vpi server [1]. This server is
now part of the ORPSoC version 3 (OpenRISC Reference Platform SoC).
The jtag_vpi server provides an interface between OpenOCD and a simulated
core.

target: clear running_alg flag after reset

After the target was reset we can be sure it's not running any
algorithm.

This fixes the following failure scenario:

On my STM32F103 board after I start the firmware and then stop and try
to "load" in gdb (before doing mon reset halt), I get

Error: timeout waiting for algorithm, a target reset is recommended

However, target reset doesn't help as the flag is still there ("Error:
Target is already running an algorithm"), so I have no choice but to
restart the OpenOCD process.

I'm not sure yet what exactly prevents load from working after my
firmware is initialised, most probably some interrupt is firing and my
handler produces a fault due to garbled RAM.

mdr32fx: support for Milandr's MDR32Fx internal flash memory

This adds example config and flash driver for russian Cortex-M3
microcontroller model.

Run-time tested on MDR32F9Q2I evaluation board; the flash driver
should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware
to test.

There're no status bits at all, the datasheets specifies some delays
for flash operations instead. All being in <100us range, they're hard
to violate with JTAG, I hope. There're also no flash identification
registers so the flash size and type has to be hardcoded into the
config.

The flashing is considerably complicated because the flash is split
into pages, and each page consists of 4 interleaved non-consecutive
"sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the
fastest way is to latch the page and sector address and then write
only the part that should go into the current page and current sector.

Performance testing results with adapter_khz 1000 and the chip running
on its default HSI 8MHz oscillator:

When working area is specified, a target helper algorithm is used:
wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s)

This can theoretically be sped up by ~1.4 times if the helper
algorithm is fed some kind of "loader instructions stream" to allow
sector-by-sector writing.

Pure JTAG implementation (when target memory area is not available)
flashes all the 128k memory in 49.5s.

Flashing "info" memory region is also implemented, but due to the
overlapping memory addresses (resulting in incorrect memory map
calculations for GDB) it can't be used at the same time, so OpenOCD
needs to be started this way: -c "set IMEMORY true" -f
target/mdr32f9q2i.cfg

It also can't be read/verified because it's not memory-mapped anywhere
ever, and OpenOCD NOR framework doesn't really allow to provide a
custom handler that would be used when verifying.

stlink: add SWO tracing support

Enable reading the SWO trace output via STLinkv2 dongles that support
it.

This adds an optional initialization parameter "trace" with which the user
specifies a destination file where SWO trace output is appended as it comes in
as well as the trace module's source clock rate.

STLink will be configured for a 2MHz SWO data rate (STLink's highest
supported rate) if the source clock is > 2MHz, otherwise the source
clock is used as the data rate directly.

For example:

trace swo.log 168000000

If "trace" is specified with a usable file path, the stlink_usb driver will
attempt to configure and read SWO trace data as follows:
- on _run(), the target's TPI and TMI are configured and the STLinkv2 is told
  to enable tracing.  Only generic ARM TPI and TMI registers are
  configured, any MCU-specific settings (ex: pin routing) are the
  responsibility of the target firmware.  The configuration applied is
  based on the STLinkv2's capabilities (UART emulation).
- on _v2_get_status(), the trace data (if any) is fetched from the
  STLink after the target status is checked and the target is found to
  be running.
- on _halt(), the STLink is told to disable tracing.

When fetching trace data, the entire trace frame is written to the output file
and that data is flushed.  An external tool may be used to parse the
trace data into a more human-readable format.

Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).

gdb_server: support File-I/O Remote Protocol Extension

The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.

To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target

As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).

To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.

Details refer to GDB manual "File-I/O Remote Protocol Extension"

mpsse: Defer errors until flush

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.

Fix out-of-tree build

The current AX_CONFIG_SUBDIR_OPTION macro assumes that $srcdir is a
relative path. If it is not, jimtcl/configure.gnu is generated such that
an out-of-tree build will fail at the configure step unless the build dir

oocd_trace: fix warnings

gcc (Gentoo Hardened 4.6.3 p1.13) produces a warning about the variable
assigned but not used. write() can sometimes write less than the specified
count so it's marked with warn_unused_result in the system headers and its
return value can't be ignored. The most correct solution would be to have a
loop writing the buffer until all bytes are written or an error is
returned but here it's impractical.

aice: fix FTBFS on ARM

This fixes a bunch of errors like this:
aice_usb.c: In function 'aice_pack_htdc':
aice_usb.c:63:4: error: cast increases required alignment of target type [-Werror=cast-align]

I think this can be seen as another justification for an ARM Jenkins

Also, the aice code I've seen so far seems to be assuming it runs on a
