Re-order the "trace" parameters to allow the raw capture (log) file to
be an optional feature. The clock frequency for calculating the "Async
Clock Prescalar" is always required when enabling trace processing and
is now the first "required" parameter.
The ST-Link driver is updated to use the (required parameter)
"trace_source_hz" non-zero value as the indicator of trace being
required, rather than the now optional output file descriptor being
non-NULL.
Background: This patch is groundwork for extending the OpenOCD SWO
capture to implement other (OpenOCD built-in) ITM/DWT processing where
the core trace support is required, but there is no requirement to
store raw trace data to a configured host file. By itself this patch
is almost a functional NOP, since without the other processing in
place there is no reason NOT to specify a capture file.

There is an remark in jtag_srst and jtag_trst variables declaration:
/*
* JTAG adapters must initialize with TRST and SRST de-asserted
* (they're negative logic, so that means *high*). But some
* hardware doesn't necessarily work that way ... so set things
* up so that jtag_init() always forces that state.
*/
but in hla_target such forsing is missed and both variables remains
uninitialized until "reset" command issued, It prevents target polling
when connecting to running target.

Due to issues reported when using the jtag mode of the stlink (see Trac #61),
the functionality/checking has been moved to the driver.
This change also fixes unaligned 32bit memory read/write for the stlink.
From testing this change also brings a 3KiB/s speed increase, this is due
to the larger read/write packets.

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).

adapter_init (core.c) won't check speed configuration
of the selected interface if it's not needed (.speed = NULL).
When it's not needed, we can now omit adapter_khz in
init scripts and we don't have to implement dummy handlers
for speed_div and khz functions.
It also removes calls to adapter_khz in interface configuration
files when not used anymore.
