Added support for the ADS1115 16-bit ADC
Updated the gpio readall command to correctly with with the Compute Module
and fixed a resulting bug in wiringPi...

Updated the gpio program to be device tree aware.

This patch is autogenerated, with:
  git-ls-files | grep Makefile | xargs perl -i~ -pe 's/^\t\@/\t\$Q /'

We want to be able to disable the many @'s in the Makefiles so
that we can see what they are doing, when things go wrong.  It is
conventional to arrange for setting V=1 to have this effect.

Here we supply a formulaic stanza for either setting Q?=@ or
doing nothing.  (There is sadly no standard place which is
included in all the Makefiles so this is probably best).

In this patch we do not introduce any users of Q yet.  This is
because the next patch, which introduces all the users of Q, can
be generated entirely automatically.  (This is also convenient in
case something needs to be rebased across it.)

Written some examples for the PiGlow board
bumped wiringPi version

bumped version.

Added the Quick 2 Wire codes, etc.
Minor typo/bug fixes.
Added more modules into gpio -x

Added in generic 'blink' programs in the examples in C, RTB and Shell.
Updated wiringPi with a little big-file on the millis() function and
added in a new micros() function too.
Updated the examples with standard LGPL headers.
Added a new isr-osc.c test program - just for ISR timing purposes.

on non Raspbian systems (and even on some Raspbian systems it would appear ):

fixed a timing issue on softTone
fixed some issues in wiringPisetup introduced when optimising the mmap calls.

and developed the new ISR - Interrupt Service Routine
handler - much easier than the old waitForInterrupt code!

Minor tweaks to the gpio program to recognise the environment variable
WIRINGPI_DEBUG too, and removed the printing of the errors from the
main wiringPi setup routines (and added some new ones!)

Also Makefile tweaks to help improve things somewhat - decided to
read the Makefile manual after some 15 years to updated my make
grey cells somewhat.

New command in the gpio command - readall

Updated wiringPi to add new PWM controls.
