- Move AC_ARG_ENABLE for secondary parallel port options:
  - These macros cause their configure options to appear unconditionally,
    so they should not be placed inside conditional logic.
  - Groups them with primary parallel port driver option.
- Update these options to show '-' instead of '_'; both still work.
- Update command help text to show host architecture/OS requirements.
- Display a warning when these options have been provided and the
  configure script will ignore the setting that the user specified.

- Try to disambiguates minidriver options from "standard" driver options.
  - Make minidummy symbols more explict about being a minidriver.
  - Move minidummy.c into minidummy directory to put it with its header.

In configure.in:
- Improve configuration option to allow new minidriver implementations:
  - Change option from --enable-minidummy to --enable-minidriver-dummy.
  - Move it to the end of the list of options.
  - Provides a clear pattern for future minidrivers.
- Update handling of HAVE_JTAG_MINIDRIVER_H:
  - Check for external jtag_minidriver.h only with --enable-ecosboard.
  - Otherwise, define it when --enable-minidriver-dummy is provided.
- Add check to ensure only one minidriver is enabled.
- When a minidriver is enabled, warn user that standard drivers are not built.
- Use proper AC_DEFINE semantics with MINIDRIVER_DUMMY.

In src/jtag/Makefile.am:
- Restructure handling of minidummy source files.
- Include minidummy driver header in the distribution.

In src/jtag/jtag.c:
- Restructure preprocessor logic to include:
  - only one minidriver, or
  - all configured standard drivers.

Let disabled targets be ignored during normal operation:

 - In target_examine(), ignore disabled TAPs

 - Reset handling must not poke at them either:
     * fail $target_name arp_* operations on disabled TAPs
     * in startup.tcl, don't even issue the arp_* wait ops 

ZW: removed superfluous braces from the patch to target.c.

the code more closely, and present things more clearly.

Various minor tweaks for the User's guide.

 - Fix various minor (but repeated) typographic goofs;
 - Talk about TAP "declaration" not "creation" (they exist
   even if OpenOCD never learns about their board);
 - Encourage board.cfg for reset config, not target.cfg
 - Fill in some missing information (e.g. x16_as_x8)
 - Add a cross reference to the FAQ on TAP ordering;
 - Unclutter the concept index a bit (re core-specific commands)
 - Provide a bit more info about TAP states
