- revert patch from rev1507 as it was causing reset issues with arm9 cores

Fix intermittent J-Link interface startup failures:
- Use usb_reset to ensure selected dongle is in known good state.
- Assert emulator reset durning status check to prevent supurious failures.
- Eliminate status check loop; not needed due to other fixes.

- Setter calls the interface driver callback to improve core encapsulation.
- Use getter in standard JTAG interface drivers and ZY1000 minidriver.

Remove pernicious whitespace from src/jtag/*c files; mostly
the end-of-line flavor for now, although there's more.

v5/6 jlink seems to have an issue if the first tap move is not divisible by 8, so we send a TLR on first power up

The debugging code in jlink_tap_execute() called when _DEBUG_USB_COMMS_ is
defined was using the entire cached scan length to print the results
buffers, and not the correct length of each individual buffer.

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
