lolunit: add a LOLUNIT_SET_CONTEXT / LOLUNIT_UNSET_CONTEXT macro pair.
This is useful when doing several asserts in one loop, for instance: there
isn't always a way to deduce the loop index from the assert failure, so
these macros allow the user to give more context information.

lolunit: reverse the expected/actual logic.
CPPUNIT_ASSERT_EQUAL(a, b) “expects” the value “a” and fails if “b” is
different. The logic seems backwards to me, but matching CppUnit’s
output is important so I’m doing the same in LolUnit.

test: replace CppUnit with our LolUnit test suite.
CppUnit is really too large for our needs, would require to be precompiled
for many platforms, in all combinations of debug and release modes, with
additional variants for libstdc++ versions. We replace it with our own
lightweight implementation, LolUnit. Good riddance.

core: minor optimisation in the x86 version of lol_sin()

magic number 2^53, which gives us the parity with at least one mul less.

to handle them.

contrib: rebuild the Win32 CppUnit under Linux and fix the includes.
Apparently g++ 4.5.2 on native mingw32 inserts references to __Unwind_Resume
when exceptions are supported. This function is not present in the g++ 4.4
cross-compiler found in Debian, leading to linker errors when cross-
compiling. So we use the latter to build CppUnit itself.
Another problem arises with g++ 4.4, which is the incomplete stripping of
exceptions when -fno-exceptions is used. Since ExceptionTestCaseDecorator.h
has such code, we protect it with #ifdef __EXCEPTIONS in the meantime.
