Doc (mostly) update for jtag_khz:
- switch to @deffn syntax
- add entry for "jtag_rclk"
- move deprecated "jtag_speed" into collection of deprecated calls
And for ft2232, don't be the only adapter to *log* an error if RTCK
is requested; it's already reported properly, like any other nonfatal
command parameter. "jtag_rclk" just works as expected, without any
scarey messages.

- Add jtag_execute_queue in jtag_add_reset after interface_jtag_add_reset.
- Use tap_set_state to demark TAP_RESET, instead of cmd_queue_cur_state
- cmd_queue_cur_state needs to be retired.

Updates to the J-Link interface driver to support more device versions:
- Add capability detection:
- if capable, detect protocol version; otherwise, assume v2 protocol.
- if capable, detect buffer size; otherwise, assume minimal.
- Disable command result queries for devices using v2 protocol.
- Defined and use JTAG2 command with v2 protocol; JTAG3 is v3 protocol.
- Add TCL command to allow explicit setting of J-Link protocol version.
With approval, I revised the patch to make the following changes:
- add static keywords to new jlink-specific variables
- factor calculation of major_version to be more readable
- remove braces around simple one-line statements in if/else clauses
- remove (rather than #if 0) duplicate reset code; it is in SVN
- use &function to be clearer when passing function pointers
- add symbols for EMU_CMD_GET_CAPS bits; do not hard-code constants!
- almost renamed jlink_handle_jlink_hw_jtag_command (seriously?!?!)
- rewrote that function using a switch statement.
- made version request processing easier to understand and modify
- improve alternate endpoint detection:
- make code easier to read by using temporary variables
- eliminate extra level of indentation and redundant logging
- use ternary conditional to select JTAG2 or JTAG3 command
- reverse version test in jlink_usb_message to reduce indentation
- this had the biggest effect in cleaning up this patch
- use C99's ability to declare new/changed variables with less scope
- add spaces around binary operators in new/changed code
- revert other superfluous whitespace/comment style changes

-jtag.c, interface_jtag_add_dr_out():
- use pointer 'field' instead of scan->fields[field_count]
- restructure the main loop to clearly separate the two cases: TAP is not bypassed / TAP is bypassed
(this is to keep the function similar to interface_jtag_add_dr_scan())
- fix bug where only the first output field has its tap field set
- add asserts to verify that target_tap points to the one not bypassed TAP

- add an assert that checks that no superfluous input fields were passed
