This is a general tidyup to detach this fork better from Gordon, who was (and perhaps still is) completely inundated with WiringPi-related support questions.

This changeset includes a number of tweaks which should reduce support burden on Gordon. I believe they are essential if we plan to release a new debian package.

They should - hopefully - not reduce or make ambiguous the origins of this code while achieving the above.

* Remove Gordon's email address from all source files to avoid support queries finding their way to him
* Update wiringPi URLs to the GitHub repository to try and keep bugs/issues within the fork
* Bump version to 2.70 ready for a debian package release
* Update debian package maintainer info, add bugs & homepage URLs to this repository

This may exist in most cases, but occasionally it does not and it aligns with the way the man page directory is pre-created as well.

Added fixed for a few minor things. pin driver for rht03/dht type
sensors. Network stuff is experimental - for now.

for kernels 4.8 onwards.

Some very old stuff might break.

Additional fixes for the ISR code and some tweaks here and
there. I've removed the checks for some operations that might
fail when using the gpiomem interface - which is now the default
way of doing things - if your program segfaults, then you
may need to use sudo on it.

Also adding in the stuff for /dev/gpiomem with warnings
and information in the gpio manual page (who reads that
though!)

help.

This makes it possible for the caller of ./build to suppress the
chown/chmod of the gpio utility.

These are not set in normal shell sessions.  Honouring existing
settings allows the caller of ./build to specify alternative values.

We are going to want to introduce a real Debian source package build
system.  But that needs to contain a lot of things in debian/ which
ought not to appear in the .deb made by the existing ad-hoc `./build
debian' arrangements, which we want to keep so as not to unduly
disturb existing users.

So rename the whole debian/ directory to debian-template/ and change
all references in the build system.

emacs complains about this line, because it thinks lines with just a
tab on in Makefiles are suspicious.  Remove the needless tab.

No functional change.

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.)

Debian package creation - crude, probably violated the Debian policys
but it seems to work just fine...
some other changes.

Moved the extensions into wiringPi from gpio and made it more general purpose
more so that RTB and anything else can dymanically add devices
into wiringPi.
Changes to GPIO to updates for the SPI and I2C module loads
Added gpio unload for SPI and I2C.

Added a new way to setup SPI - by passing the mode in.

Support for the new Pi2 thing too

bugfix in blink.sh - wring pin
improving the maxdetect routing - a little.
gpio pins

Tweaked the mcp3422 code
altered the build script to let me build static

mcp3004.c bugfixed. It works now!

Added new code for max31855

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.
