Remove also some macros which are no longer needed.

That restores commit 25e0c1ac and
partially revert commit 4907a23f
which added the now unused Shlwapi library.

Fixes from pull of cleanups: clang tidied, reviewed, fixed new bugs, undeleted needed code. Probably breaks the build, due to some inclusion of changes in utf8/32 conversion

That allows removing a dirty hack which used the
non-portable function strcasestr.

The size() method returns a size_type value which is an unsigned type.
As there is no portable format string for that type, a type cast is needed.

Fix also several signed / unsigned mismatches which resulted in compiler
warnings.

The code in ccutil/hashfn.h was needed for some old compilers. Now that we support MSVC >= 2010 and compilers that has good support for C++11, we can drop this code.

As a result of this file removal, we now use:
  std::unordered_map
  std::unordered_set
  std::unique_ptr
directly in the codebase with '#include' for the needed headers.

Commit 65504c8c misplaced the #endif.
The definition of _GNU_SOURCE is only needed for Cygwin.

Defining _GNU_SOURCE on Linux results in compiler warnings because this
macro is already defined by the compiler.

Fix this by moving the #endif to the right place. In addition the code
for Cygwin is made more robust: If a future Cygwin compiler defines
_GNU_SOURCE, too, the code will still work.
