Raspberry Pi v3 support.

We are going to want to not run sudo sometimes.  So replace literal
invocations of sudo with a variable, which is set to `sudo' by
default, but can be overridden from the environment.

No functional change if the environment variable is not set.

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.

We need to -I and -L the build tree directories, not the directories
in /usr/local or wheveever.  Otherwise (a) the `./debian build' fails
if wiringPi is not installed (b) if it _is_ installed, the build picks
up the installed versions rather than the versions being built, which
is wrong.

So that shell scripts do not blunder on after errors.

the same as everyone elses.

This is an interim version which will work on both Pi v1 and v2
boards until I have a bit more time to implement the correct
stuff for v2.

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

of changing it for the B+)

Aded a gpio command: usbp hi/low - to change the usb power

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

Written some examples for the PiGlow board
bumped wiringPi version

with wiringPiISR.
Added the ability to readall/reset from extension modules.
Changed the build script to use /bin/sh rather than /bin/bash as it seems
some installations don't have /bin/bash (or if they do, then the people who
are telling me that ./build gives them command not found are wrong)

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

I2C libraries again - but only if the right headers are
installed!

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.

(hopefully!)
Also updated all the mmap code in wiringPiSetup() to make it a bit more
sane and efficient to a degree.

libraries.
Bumped gpio version.

Changed built to work marginally better.

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

Added top-level build script for lazy building.
