TODO: to create symlinks to the old names!

(worked with BSD sed but no GNU sed...)

Detects uninitialised memory reads. Available only with Clang on Linux x86_64
for now. Experimental but seems usable enough.

- warnings in debug build allows the to be caught earlier
- -Werror with ASan make tests/scripts/all.sh a bit shorter

The data produced by gcov for static inline functions is too unreliable to be
actually useful. Some lines that are covered are not marked as such, some
other static inline functions are completely ignored, and the reasons why do
not look obvious.

On Xcode 4.x and above (I tested Xcode 4.6.3 on 10.7.5 and Xcode 5.5.1 on 10.9.2), cmake (2.8.12.2, whether from MacPorts or from clang.org, FWIW) is detecting /usr/bin/cc as Clang, but CMAKE_COMPILER_IS_CLANG is not getting set, so the tests aren't being built. (There may have been other build problems as well, but the fact that the tests weren't being built was by far the most obvious problem.)

Checking the compiler ID detected by cmake, rather than the name of the command used to invoke the compiler, fixes this.

ZLIB_INCLUDE_DIR was interpreted as a relative path from the
working directory.

Adding optimization level to CMAKE_C_FLAGS is intrusive and problematic
with policies of various distribution.
However, setting "-O2" in CMAKE_CFLAGS_RELEASE is fine and only
affects release build.
