Comment:
This patch implements an object 'xreadlines' in C, as well as a method on the file object to create one.

xreadlines will let a 'for' loop iterate over the contents of a file without reading the whole file, yet at a speed almost equal to that of 'for line in f.readlines()'.  Internally, it uses f.readlines(sizehint).

Includes a test suite and a version of fileinput which uses it (approx. 50% speedup in fileinput as well).  fileinput is not tested by test suite entry.
