uart.c contains a static conversion function that will translate known
baud rates into their speed_t counter parts. If an unsupported baud
rate is selected, a diagnostic will be emitted via syslog and a
default of B9600 will be chosen.

This requires setting #define SWIG_V8_VERSION 0x032873 in the
mraajsJAVASCRIPT_wrap.cxx file. Note most v8 APIs now require v8::Isolate and
v8::Persistent is no longer a v8::Handle so the gpio.hpp for ISR support is
also modified by this change

This stops the error code getting lost since -1 wraps around to 0xFF when cast
to a uint8_t. This fixes#146

This commit adds isr support to node.js mraa module, it also forces
SWIGJAVASCRIPT to be set at compile time by cmake (SWIG uses SWIGJAVASCRIPT and
not SWIGNODE in it's preprocessor). This uses libuv uv_queue_work to call v8isr
and is all done at a C++ level unlike the python isr, so this reuses the
mraa_gpio_isr call. This closes#110

Instead of plain char* to avoid need to malloc and do all the needed

Used for getting the path to the character device under linux for uart

Adds paths to existing platforms.

There is an issue that when you take an IO pin that has an external PU
resistor and switch it from INPUT to OUTPUT the state of the pin will go
down before you can set it back high.

This means that you can initialise a non raw Pwm pin without having to redefine
chipid as -1 (anything but -1 enables raw mode for Pwm)
Fixes#93.

This change also changes the C++ API write(char) call to writeByte(uint8_t) and
the write() call now takes a uint8_t* instead of a char*. This should not alter
any code significantly and does not affect the C API.

I2c class now uses more C like constructs for added efficiency when using C++
and no longer returns a binary string when doing read() calls. This change also
removes the use of std::string in the SWIG API for read/write which never
worked very well. This also renames single write/read calls to {write,read}Byte
as whilst overloading works in C++ well it's a little confusing and only works
because {write,read}() calls have 2 arguments which will not be the case in the
SWIG API where those calls take a single argument (bytearray or node::Buffer),
especially in js where functions have no explicit args this does not work well.
