Hannes Steffenhagen 856aa5c201 Make memory analyzer optional 
We were doing this in multiple places, this should make it a bit easier to keep
set properties consistent among different places.

Ideally we could eventually move away from mentioning targets from modules here
on the top level (and instead have each module call cprover_default_properties)
but this isn't done in this commit.

Because memory analyzer depends on GDB being present and further uses platform
specific functionality at the moment it had some ifdef functionality to disable
itself.

This made the code a bit more complicated than it needed to be, and also lead to
the code effectively building defunct executables. This removes these ifdefs and
instead excludes memory-analyzer (and related tests) from the build unless
requested (via WITH_MEMORY_ANALYZER environment variable or CMake option
depending on whether it is a Make or CMake build respectively).

Also force building memory-analyzer on Linux and test it there by
default (unless explicitly unset). Behaviour on other platforms should be
preserved.

About

CBMC is a Bounded Model Checker for C and C++ programs. It supports C89, C99, most of C11 and most compiler extensions provided by gcc and Visual Studio. It also supports SystemC using Scoot. It allows verifying array bounds (buffer overflows), pointer safety, exceptions and user-specified assertions. Furthermore, it can check C and C++ for consistency with other languages, such as Verilog. The verification is performed by unwinding the loops in the program and passing the resulting equation to a decision procedure.

For full information see cprover.org.
