Command line arguments handling overhaul

- login_server, char_server, map_server as well as the tools (mapcache)
  now have a common command line arguments handling mechanism.
- All of them now accept `--help` (`-h`), `--version` (`-v`) and
  `--load-plugin`.
- login_server now accepts `--login-config` and `--lan-config` instead
  of relying on positional arguments to override those files. The old
  syntax will no longer work, please update your custom startup scripts.
- char_server now accepts `--char-config`, `--inter-config`,
  `--lan-config` instead of relying on positional arguments. The old
  syntax will no longer work, please update your custom startup scripts.
- mapcache now accepts `--grf-list`, `--map-list`, `--map-cache`,
  `--rebuild` in place of, respectively, `-grf`, `-list`, `-cache`,
  `-rebuild`.
- A new macro `CMDLINEARG()` is provided, to help defining new command
  line argument handlers (i.e. in plugins). the `addArg()` call is still
  required, but its syntax has changed. The `help` argument is now of type
  `const char *` rather than a function pointer, and it is supposed to
  contain the message to show in the `--help` screen. Pass `NULL` if no
  help message is desired.
