The previous one sqeezed unnecessary whitespaces and joined function type
and name in the definition split across lines. This patch further fixes
many remaining style issues:
- We are not particularly fond of typedef to hide the underlying struct
definitions.
- Asterisk comes next variable, i.e. "type *var", not "type * var" nor
"type* var".
- Casting to pointer to a type is "(type *)", not "(type*)".
- An open brace comes on the same line as closing parenthesis of "if (...)"
condition; "else" comes on the same line as closing brace of its
corresponding "if (...) {".
- Avoid single liner "if (...) <stmt>;"; they should be on two separate
lines.
