Trac #12555: Reimplement elements of Zp and Qp using templates

The goal of this ticket is to reimplement elements of Zp and Qp using
the ideas from sage/rings/polynomial/polynomial_template.pxi.  This
should make p-adics in Sage both easier to maintain and easier to add
new classes.

The final patch should not affect the external interface to Zp and Qp.

Trac #15561: freetype 2.3.5 is too old for some fonts of current systems.

The now-current freetype library has problems with newer fonts. This
forbids its uses in some applications on machines having system fonts
not supported by this version.

This was diagnosed on sage's R (see
[https://groups.google.com/forum/#!topic/sage-support/FnTEcpfg6wE this
thread]) by Volker Braun.

A stopgap measure is to upgrade freetype to a more forgiving version of
freetype, hence this ticket.

The current freetype tarball hits a snag in libpng, because it uses
setjmp for exception handling, which triggers a compiler error due to
this settinng up been made twice. So a small patch to the current libpng
is part of this branch.

New tarball: http://download.savannah.gnu.org/releases/freetype/freetype
-2.5.2.tar.bz2
