Tooling such as clang-tidy is bad at dealing with condition compilation on the build system level instead of at the source file level. What happens? It still tries to analyze the file and fails horribly if the required headers aren't available. Let's work around the issue and make things more consistent at the same time by doing the necessary HAVE_GCRYPT checks inside of the source files instead of doing them at the build system level. We also add some typedefs to allow getting rid of various HAVE_GCRYPT checks.
