Every time a cell is allocated, the interpreter may run out of free
cells and do a garbage collection. This is problematic because it
might garbage collect objects that have been allocated, but are not
yet made available to the interpreter.
Previously, we would plug such newly allocated cells into the list of
newly allocated objects rooted at car(sc->sink), but that requires
allocating yet another cell increasing pressure on the memory
management system.
A faster alternative is to preallocate the cells needed for an
operation and make sure the garbage collection is not run until all
allocated objects are plugged in. This can be done with gc_disable
and gc_enable.
This optimization can be applied incrementally. This commit picks all
low-hanging fruits.

The previous Bourne Shell-based test suite created the environment
before running all tests, and tore it down after executing them. When
we created the Scheme-based test suite, we kept this design at first,
but introduced a way to run each test in its own environment to
prevent tests from interfering with each other. Nevertheless, every
test started out with the same environment.
Move the creation of the test environment into each test. This gives
us finer control over the environment each test is run in. It also
makes it possible to run each test by simply executing it using gpgscm
without the use of the runner. Furthermore, it has the neat
side-effect of speeding up the test suite if run in parallel.
