  1. src/sage/symbolic/integration/integral.py: use libgiac for "giac" int… 

    …egration

The library interface to libgiac is much more efficient than the
pexpect one, but the name algorithm="giac" is more attractive
(especially to newcomers) than algorithm="libgiac". We should just
Do The Right Thing and use libgiac when "giac" is requested.

  2. src/sage/symbolic/integration/external.py: drop pexpect giac integrator 

    The pexpect integrator is unused now that the "giac" integrator uses
libgiac. We also add a few "# needs sage.libs.giac" tags to the tests
that use the libgiac integrator, because they obviously will fail when
libgiac is not there.

  3. src/sage/calculus/calculus.py: add "needs" for libgiac integration 

    One example in this file integrates with algorithm='giac', which can
fail if sage.libs.giac is not available to perform the integration.

A few examples in this file integrate with algorithm='giac', which can
fail if sage.libs.giac is not available to perform the integration.
