pj_make_args is the inverse of the pj_trim_argc/pj_trim_argv combo: It
converts free format command line input to something proj_create can consume.

Allocates, and returns, an array of char, large enough to hold a whitespace
separated copy of the args in argv. It is the duty of the caller to free this
array.
