[PATCH] Handle variable width encodings in basic_filebuf::seekpos


This patch adds support for variable width encodings to
basic_filebuf::seekpos. The necessary code was already present in
seekoff, so I moved it into a separate function (_M_seek) and
called that from both seekoff and seekpos.

While testing the patch, I got a spurious failure in
testsuite/22_locale/locale/cons/ It seems the memory limit
was set too low to run the loop even once. I doubled both the
memory limit and the loop count to make the test pass.

Tested on i686-pc-linux-gnu.
