* Updated README.md

Nuncio devel

Added gpio readall support for the Pi 0W.

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

Fixed some compiler warnings.
New wiringPi version mechanism.
Put 4800 baud (back) into the system.
Re-added piBoardRev (really an alias of piGpioLayout())

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.

Updating the GPIO command - new command - allreadall
ScrollPhat code
max31855 code (tested with adafruit breakout board)
more tests
updated rht03 code

Raspberry Pi v3 support.

PULSE_TIME wasn't used.

delete duplicated FSEL_ALT0 definition.

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...

Also affects the Pi v2 which also uses the new Revision
encoding scheme (It was slightly bodged before) This ought
to be relatively future proof, but who knows.

Fixed a minor thing in the examples Makefile
(not that anyone bothers to use it, judging by the emails I get )-:

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

Updated the gpio program to be device tree aware.

help.

It's not perfect - there is no symbol versioning, and I have had to
make some (perhaps false) assumptions about library ABI stability, but
it does produce something vaguely resembling what would be expected
from a library package found in Debian, and it does so using the
standard Debian source format.

This makes it possible for the caller of ./build to add a version
number to the sonames of the shared libraries.  (This is required for
Debian packages.)

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

This is not set in normal shell sessions.

Honouring an existing setting of LDCONFIG allows the caller of ./build
to specify an alternative program to run.

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.

The symlink libwiringPiDev.so was mistakenly created pointing to
libwiringPi.so.$(VERSION) (note lack of Dev), ie to the wrong library.

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.

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.
