Parses the command line arguments.
This function is similar to parse except that it respects the normal memory rules when dealing with a strv instead of assuming that the passed-in array is the argv of the main function.
In particular, strings that are removed from the arguments list will be freed using g_free .
On Windows, the strings are expected to be in UTF-8. This is in contrast to
parse which expects them to be in the system codepage, which is how they are passed as
get_command_line for a solution.
This function is useful if you are trying to use OptionContext with
a pointer to the command line arguments (which must be in UTF-8 on Windows). Starting with GLib 2.62,
true if the parsing was successful, false if an error occurred
