Use consistent formatting of all code

Inconsistent code formatting is confusing to beginners who may not understand which code differences are purely aesthetic. Inconsistency also breeds more inconsistency and inefficiency as contributers of example code struggle to determine any style convention to follow in their work.

AStyle (the tool used for the Arduino IDE's Auto Format feature) was used to automatically format the example code in the reference pages according to the standard Arduino style established in the official example sketches bundled with the Arduino IDE. The Auto Format formatting settings were used in addition to Arduino example formatter configuration:
https://github.com/arduino/Arduino/blob/1.8.8/build/shared/examples_formatter.conf
I used the latest version of AStyle, which offers some new configuration settings that allow enhanced compliance with the Arduino code style:

mode=c

style=attach

break-closing-braces
attach-closing-while
attach-namespaces
attach-classes
attach-inlines
attach-extern-c

indent=spaces=2
indent-classes
indent-switches
indent-cases
indent-col1-comments
indent-modifiers
indent-namespaces
indent-labels
indent-preproc-define

pad-header
pad-oper
unpad-paren

add-braces

remove-comment-prefix
convert-tabs
align-pointer=name
