builtin/config: work around an unsized array forward declaration
As reported here[0], Microsoft Visual Studio 2017.2 and "gcc -pedantic" don't understand the forward declaration of an unsized static array. They insist on an array size: d:\git\src\builtin\config.c(70,46): error C2133: 'builtin_config_options': unknown size The thread [1] explains that this is due to the single-pass nature of old compilers. To work around this error, introduce the forward-declared function usage_builtin_config() instead that uses the array builtin_config_options only after it has been defined. Also use this function in all other places where usage_with_options() is called with the same arguments.
