Apa102 fix if the led strip has more physical LEDs than you want to configure with hyperion (#626) * 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 * started bug fixes for APA strips with more physical leds than configured * 1st cut of changes to APA102. now looks at config for "leds" which is the # of hardware leds in the strip. This enables us to write the correct trailer length in the packet. Also fixed a bug where switchoff was writing the wrong # of leds * removed commented out old code removed debug printf * included prebuild test binary for Pi2 * Second attempt at the fix. BEFORE: If you have more physcial LEDs than defined in the "leds" "index" section of the config there is random junk added to the end of the strip. WITH THIS FIX: In the "device" section specify the number of physical leds with: "leds" : 212, If this is greater than the number of led indexes, additional LEDs are set to black If this is smaller than the number of led indexes, it is ignored * included test binary * Clean exit if the device config is missing or a non-supported device type is specified Former-commit-id: 8ae96188fa74d91b13a921e7d5faf6d6ac1c42ee
