Move builds to CircleCI build service

Build on circleci, should be much faster.

Un-align input byte arrays to catch assumptions about data alignment

Greatly simplify container builds

Set windows warnings to W4

Faster check of makefile dependencies

We do not actually need to compile the files.

Detect use of dynamic memory allocation functions

Don't always Make clean; Undoes a7328f8

The intention of this build rule is not to do a clean build, but to make sure the files in the target scheme are up to date when running the tests.

Include name of implementation in namespace

Add test to check that every .c / .h file triggers a library rebuild

Build functional tests and test vectors on Windows continuous integration

Enable address and UB sanitizers

This enables address sanitizer and undefined behaviour sanitizer,
but disables leak detection sanitizer.
It seema there is an issue in qemu that we are using, which prevents
spawning leaksanitizer's tracer thread. But as leak detection is
already done by valgrind on x86 build, this functionality is not
absolute need at the moment.

Test for symbolic links
