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.

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

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

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)

the module.
Typo in gpio man page
Bug fixed in board revision detection (which would never happen
anyway, however)

one of the GPCLK drivers to generate a frequency up to
19.2MHz.

Tidied some code up and added the clock functions into the gpio
utility.

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.

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!)

delayMicrosecondsHard re-written - again.
Added a serialRead example program, and added in the okLed
to the examples too.
Updated/checked some of the GPIO/PWM code.
Added in some experimental servo and tone generating code and
and example or 2.
Tweaks to the gpio command to correctly load the I2C modules too.

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

Changed the gertboard code to use it
and ran more tests on he Gertboard code.

Updated wiringPi to add new PWM controls.
