Use a wrapper around getopt() for portability. This uses the system getopt()
whenever possible, and otherwise uses a stripped down, single options only, BSD getopt() (which is smaller and doesn't come with ifdef-stuff-in-features.h.) git-svn-id: https://svn.xiph.org/trunk/ezstream@15779 0101bb08-14d6-0310-b084-bc0e0c8e3800

The LONG_OPTIONS argument to getopt_long or getopt_long_only is a vector

of `struct option' terminated by an element containing a name which is

zero.
|

|

The field `has_arg' is:

no_argument (or 0) if the option does not take an argument,

required_argument (or 1) if the option requires an argument,

||||
optional_argument (or 2) if the option takes an optional argument.

If the field `flag' is not NULL, it points to a variable that is set
|
||||
to the value given in the field `val' when the option is found, but
|
||||
left unchanged if the option is not found.
|
||||
|
||||
To have a long-named option do something other than set an `int' to
|
||||
a compiled-in constant, such as set a value from `optarg', set the
|
||||
option's `flag' field to zero and its `val' field to a nonzero
|
||||
value (the equivalent single-letter option character, if there is
|
||||
one). For long options that have a zero `flag' field, `getopt'

returns the contents of the `val' field. */
