Angus Gratton 821c70f5d7 examples: Standardise naming of files, symbols, etc. in examples 
* Use "example" in all example function & variable names,
  ie use i2c_example_xxx instead of i2c_xxx for example functions.
  Closes #198 https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

Example: GPIO

###This test code shows how to configure gpio and how to use gpio interrupt.

####GPIO functions:

  • GPIO18: output
  • GPIO19: output
  • GPIO4: input, pulled up, interrupt from rising edge and falling edge
  • GPIO5: input, pulled up, interrupt from rising edge.

####Test:

  • Connect GPIO18 with GPIO4
  • Connect GPIO19 with GPIO5
  • Generate pulses on GPIO18/19, that triggers interrupt on GPIO4/5
