And many more.

GCC5 defaults to -std=gnu11, which has different semantics for inline than
previous versions:

https://gcc.gnu.org/gcc-5/porting_to.html

Which causes linker issues when display_headers() and start_log() are
referenced from other files.  There's no real reason why these needs to be
inline, so just drop the keyword.
