82f2492138 ADIv5: more messaging cleanup, docs
When the TAR cache was explicitly invalidated, don't bother
printing it; the actual hardware status is more informative.

Provide some doxygen for the MEM-AP setup routine.

f68dff6690 telnet: fix strage blank spaces at beginning of telnet lines
Sometimes we saw two strange blank spaces at the beginning
of the telnet lines.

The code changes are *reasonably* clean, but perhaps it could be
made a bit more elegant, but I didn't want to change things after
I finished diagnosis/testing & submitting the patch.

The problem was that logging can send the text and the newline
separately in two different requests and the telnet code would
incorrectly remove the prompt from the end of a line.

e11ce3e6b0 Subject: ADIv5: fix more diagnostics
If the MEM-AP cache is invalid, don't display it; just report that
invalidity as an error.  (This bug has been observed with "mdw 0 32"
after just a "reset halt".  Some code is being wrongly bypassed...)

If it's valid, display that cache at DEBUG level, not ERROR.  Also,
don't assume it's an AHB-AP; it could be another flavor of MEM-AP.

3d3128a8f5 ADIv5: cleanup, rename swjdp_transaction_endcheck()
Make messages reference "DAP" if they're actually transport-agnostic, or
"JTAG-DP" when they're JTAG-specific.  Saying SWJ-DP is often wrong (on
most Cortex-A8 chips) and is confusing even if correct (since we don't
yet support SWD).

Rename a JTAG-specific routine to jtagdp_transaction_endcheck() to highlight
that it's JTAG-specific, and that identify DAP clients undesirably depending
on JTAG.  (They will all need to change for SWD support.)

Shrink a few overlong lines of code.  Copy a comment from code removed
in a previous patch (for the ARMv7-M "dap baseaddr" command).

Building with clang took a few very small changes. The change to

result is unused. In helper/system.h, I just defined true and false

3172be80a3 Cortex-M3: report lockup, and recover
ARMv7-M defines a "lockup" state that's entered in certain double
fault sequences which can't be recovered from without external help.
OpenOCD has previously ignored this.

Issue a diagnostic saying the chip has locked up, and force exit
from this state by halting the core.  It's not clear this is the
best way to handle lockup; but there should now be less confusion.

33fc60befc SVF: all content between parentheses is one parameter
More SVF fixes:

 * Treat all content between parentheses as part of the same
   parameter; don't (wrongly) treat whitespace as a delimiter.

 * Use isspace() to catch that whitespace; it's not all single
   spaces, newlines etc are also valid.

 * When parsing bitstrings, strip leading whitespace too.

So for example, these are equivalent and should (now) be OK:

  "TDI( 1234 )"
  "TDI( 1 2 3 4 )"
  "TDI(00 12 34 )"
  "TDI(
  	00 12
	34)"

9ff16575d2 SVF: insert space before '(' and after ')'
See http://forum.sparkfun.com/viewtopic.php?p=90983#90983 for discussion;
basically, the SVF parser wrongly expects "TDI (123)" but the space is
optional and it should accept "TDI(123)" too.

In the same way, "TDI(123)TDO(456)" should work too.

Rather than update the command parsing, this just makes sure the expected
spaces are present.
