Subject: Rename all identifiers to strict Linux snake_case
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Types PascalCase→snake_case, functions camelCase→snake_case,
static functions get _s_ prefix, globals get g_ prefix,
struct members and locals to snake_case.
