[PATCH] Cleanup of __basic_file and streambufs

[Pétur Runólfsson]

Hi,

This patch removes some cruft from __basic_file, basic_streambuf and
basic_filebuf.

Of these, sys_ungetc was obsoleted in May, when cin stopped using
basic_filebuf for syncronized mode. The changelog doesn't say what
happened to the others.

Tested on i686-pc-linux-gnu.
