Subject: delete deprecated IO-like methods

This commit deletes
{IO,ARGF,StringIO,Zib::GZipReader}#{bytes,chars,lines,codepoints}, which
have been deprecated since c47c095b9740e7c19d6fdca29ab661c1089221d4.

Note that String also has those methods.  They are neither depreacted
nor deleted because they are not aliases of counterpart each_something.
