Is it possible to let tmux support extension written in C

[Freed-Wu]

1. User can write a tmux extension in C and compiled to a shared library. such as:

#include <tmux.h>
int tmux_hello(int argc, char **argv) {
  tmux_display_message("hello, world!");
  return 0;
}

2. Then tmux load-extension hello.so
3. Then we have a new subcommand tmux hello to print a greeting 😄

It just be a crazy idea inspired by zsh module. In zsh, we can create module by #include <Zsh.h> then compiled a foo.so, then zmodload foo to get new builtin commands.
