The out only version of jtag_add_dr_scan smells like a bogus optimization
that complicates the minidriver API for questionable gain.
The function was only used by four old ARM targets. Rewrite the callers
to use the generic function and remove all implementations.

In the code a single field was all that was ever used. Makes
jtag_add_ir_scan() simpler and leaves more complicated stuff
to jtag_add_plain_ir_scan().

jtag_add_dr/ir_scan() now takes the tap as the first
argument, rather than for each of the fields passed
in.
The code never exercised the path where there was
more than one tap being scanned, who knows if it even
worked.
This simplifies the implementation and reduces clutter
in the calling code.
use jtag_add_ir/dr_plain_scan() for more fancy situations.

after clocking out a tms sequence, then the TAP will be
in some state. This state is now handed to the drivers.
TAP_INVALID is a possible state after a TMS sequence if
switching to SWD.

For support of SWD we need to be able to clock out special bit
sequences over TMS or SWDIO. Create this as a generic operation,
not yet called by anything, which is split as usual into:
- upper level abstraction ... here, jtag_add_tms_seq();
- midlayer implementation logic hooking that to the lowlevel code;
- lowlevel minidriver operation ... here, interface_add_tms_seq();
- message type for request queue, here JTAG_TMS.
This is done slightly differently than other operations: there's a flag
saying whether the interface driver supports this request. (In fact a
flag *word* so upper layers can learn about other capabilities too ...
for example, supporting SWD operations.)
That approach (flag) lets this method *eventually* be used to eliminate
pathmove() and statemove() support from most adapter drivers, by moving
all that logic into the mid-layer and increasing uniformity between the
various drivers. (Which will in turn reduce subtle bugginess.)

Low latency low CPU processing power systems(embedded)
will benefit greatly from being able to inline certain
jtag_add_xxx() fn's. The trick is that this has to be
done in such a way as to allow implementing an OpenOCD
API with a shared library(eventually) on a PC hosted
OpenOCD.

Removes the 'extern' keyword from function declarations.
Wraps long prototypes to fit into 80 columns.
Fixes documentation for jtag_tap_s::{,has}idcode fields.
this fn has something to do with the queue, which it does not as such.

- Wraps all minidriver API functions using API front-ends:
- Outlines jtag_add_dr_out() and jtag_alloc_in_value32().
- Adds interface_ prefix to existing jtag_alloc_invalue_32 routines.
- Re-inline these interface definitions in new header file.
- Re-inline parts of the (mini)driver implementations in minidriver.h.
- Replace INCLUDE_JTAG_MINIDRIVER_H with #include directives.
The next patch will finish removing '#ifdef HAVE_JTAG_MINIDRIVER_H'
from jtag.h.
