	Added gzip, deflate decoding support in HTTP using libz. If 
compiled
	with this feature, aria2 sends "Accept-Encoding: deflate, gzip" 
header
	to a HTTP server. If a server returns "Content-Encoding: gzip" 
or
	"Content-Encoding: deflate" then, aria2 decodes the response 
body on the
	fly and writes decoded data to a local disk.

	* README.html
	* configure.ac
	* m4/aria2_arg.m4: Added ARIA2_ARG_WITH and ARIA2_ARG_ENABLE, 
they are
	wrapper function for AC_ARG_WITH and AC_ARG_ENABLE respectively.
