Move the discussion of the "scan_chain" command up to go with
the presentation of that topic in the TAP declaration chapter.

This makes the presentation of the TAP and target lists be
parallel, which will be something of an aid to understanding
that they are different (and how).

Partial fix to the "long IR length" problems.

 - Current code could handle up to 32 bit IR lengths with
   full functionality, if it didn't just reject may of them
   out of hand.  So only reject clear errors, where the IR
   mask (or capture instruction) needs more than IrLen bits.

 - Longer IR lengths can only be handled in BYPASS mode
   for now.  Example:  TI's DSPs use 38-bit IR lengths.
   So we can't issue their IDCODE instructions...

A more complete fix would be able to issue longer instructions;
or minimally, would fail cleanly for the non-BYPASS case.

Note that this *could* make some currently broken scripts fail,
since the previous code accepted garbage values so long as
they didn't use more than 16 bits.

- Move the mips32_..._read_mem calls to top-level of read_mem function.
- Change: Only perform mips_m4k_read_mem conversion when retval == ERROR_OK.  
   - Prevents pointless conversions of bogus read values after failures.
- Eliminate retval variable from mips_m4k_write_mem; return directly.
- Move declaration of retval variable to point of first use.
- Remove the now redundant switch statements testing size:
  - argument sanitizing already covers these cases.

This patch helps fix MIPS big endian (elf32-tradbigmips) targets.
If "-endian big" is not set in target create, the endianess defaults to
little.  mw and md commands will still work, but binary file loads will
have the incorrect word order loaded into memory.

The EJTAG processor access data register (PrAcc) is little endian
regardless of the CPU endianness; it is always loaded LSB first. This
is confirmed by the fact that mips_ejtag_drscan_32() uses buf_set_u32()
to load the scan field; buf_set_u32() is a little-endian formatter. For
big endian targets, data buffers have to be modified so the LSB of each
u32 or u16 is at the lower (first) memory location.  If the drscan
out_value word order is set using buf_set_u32() then it makes sense to
also fixup the in_value with buf_get_u32(); a symmetry argument. This
has no affect on little endian hosts.

Rework the "Simple Configuration Files" chapter so it's more
of a quick-start "how to set up your project" tutorial:

 - Say how to hook up the JTAG adapter.  This will help new
   users, and in any case is worth spelling out somewhere.

 - Streamline the previous rather haphazard presentation,
   filling in some missing holes along the way:

     * Suggest "project directory" structure
     * Introduce new term, "user config" file (openocd.cfg)
     * Talk about more options for openocd.cfg contents
     * ... and about creating new config files
     * Add new topic, project-specific utilities (+examples)

 - Remove too-short, yet duplicative, chapter 19

Nudge packagers a bit more strongly to send patches (including
config files) upstream.

Update "arm9tdmi vector_catch" command description to highlight both
use cases (display configuration, or first change that config) and
to explain a bit more about what this is:  an alternative to using
hardware breakpoint resources.

Note that I tried this on an arm920t, but it didn't work.  Set bits,
then examined them and they weren't set.  And it didn't seem to act
as if vector triggering was noticed, either.

Also some minor unrelated tweaks:  @ignore some unused or don't-use
event names; fix a few typos; tweak chip-specific reset descriptions.
