Description
-------

I'm going to need this for my imminent manager and config
enhancements but I thought I'd post this separately.

/*!
  \brief Act like strsep but ignore separators inside quotes.
  \param s Pointer to address of the the string to be processed.
  Will be modified and can't be constant.
  \param sep A single character delimiter.
  \param flags controls whitespace and quote stripping.
  \return The next token or NULL if done.

  This function acts like strsep with three exceptions...
  The separator is a single character instead of a string.
  Separators inside quotes are treated literally instead of like separators.
  You can elect to have leading and trailing whitespace and quotes
  stripped from the result.

  Like strsep, ast_strsep maintains no internal state and you can call it
  recursively using different separators on the same storage.

  Also like strsep, for consistent results, consecutive separators are not
  collapsed so you may get an empty string as a valid result.

  Examples:
  \code
	char *mystr = ast_strdupa("abc=def,ghi='zzz=yyy,456',jkl");
	char *token, *token2, *token3;

	while((token = ast_strsep(&mystr, ',', AST_SEP_STRIP))) {
		// 1st token will be aaa=def
		// 2nd token will be ghi='zzz=yyy,456'
		while((token2 = ast_strsep(&token, '=', AST_SEP_STRIP))) {
			// 1st token2 will be ghi
			// 2nd token2 will be zzz=yyy,456
			while((token3 = ast_strsep(&token2, ',', AST_SEP_STRIP))) {
				// 1st token3 will be zzz=yyy
				// 2nd token3 will be 456
				// and so on
			}
		}
		// 3rd token will be jkl
	}

  \endcode
 */
char *ast_strsep(char **s, const char sep, enum ast_strsep_flags flags);
