Make the serf.def file a proper target in the CMake build, so that it gets
regenerated during the build if any of the public headers change.
* CMakeLists.txt: Use the current source directory everywhere to keep
references localised for external scripts. Add a custom target for
generating the serf.def file.
* build/SerfWindowsGenDef.cmake: New script, generates the .def file.
* build/SerfWindowsGenDef.cmake: Make the regular expressions more readable.
