Avoid use of Z_BUF_ERROR in gz* functions except for premature EOF.
Z_BUF_ERROR was also being used for an unsuccessful gzungetc and for buffer lengths that didn't fit in an int. Those uses were changed to Z_DATA_ERROR in order to assure that Z_BUF_ERROR occurs only when a premature end of input occurs, indicating that gzclearerr() can be used.
