c179b86b8d fix LedDeviceWs2812SPI to compile on gcc 4.6 (#643)
* Removed -HUP so the default -TERM signal is sent instead.
- hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config

Changed pgrep to add '-x' so it wont partial match on the exe name.
- I have multiple instances with multiple hyperiond-instance1 names
- this ensures the service script only kills the right process

* reversing errant change to hyperion.systemd.sh

* cleaned up a couple of compiler warnings

* moved bitpair_to_byte initialiser to (hopefully) work with older GCC

* compiler warning in udp driver
removed some tabs in ws2812b.cpp

* formatting - spaces to tabs

a960894d14 Another option for Ws2812 - direct spi from the pi with 1 wire (#631)
* Removed -HUP so the default -TERM signal is sent instead.
- hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config

Changed pgrep to add '-x' so it wont partial match on the exe name.
- I have multiple instances with multiple hyperiond-instance1 names
- this ensures the service script only kills the right process

* reversing errant change to hyperion.systemd.sh

* This add a new device type - ws2812spi.

I've (ab)used the SPI interface to send the correct timing pulses to keep the ws2812 happy.
THE RATE IS IMPORTANT!
A FIXED CORE_CLK IS IMPORTANT!

Attach the SPI MOSI pin on the Pi to the DIN pin on your ws2812

        "device" :
        {
                "name"       : "MyPi",
                "type"       : "ws2812spi",
                "colorOrder" : "grb",
                "output"     : "/dev/spidev0.0",
                "rate"       : 3800000
        },

* updated hyperiond.test-binary

* Updated default SPI speed to the "correct" value.
My Pi was undervolted so was dropping the core clock confusing everything

* Code cleanups
explicitly set the final 3 bytes to 0

* Removed latchtime option - not applicable

* updated test binary
