It seems that 'clang' compiler applies strict protection on pointer
dereference. And it causes unexpected execution in macro functions
like "HMAP_FOR_EACH()" and unit test failures. This commit fixes
this issue and pass all unit tests.

Casts are sometimes necessary. One common reason that they are necessary
is for discarding a "const" qualifier. However, this can impede
maintenance: if the type of the expression being cast changes, then the
presence of the cast can hide a necessary change in the code that does the
cast. Using CONST_CAST, instead of a bare cast, makes these changes
visible.
Inspired by my own work elsewhere:

This commit makes several library headers suitable for inclusion in C++.
It adds [extern "C"] guards and makes minor changes to fix casting and
keyword issues.
Many uses of "shash" or "svec" data structures really call for a "set of
strings" data type. This commit introduces such a data structure. Later
commits convert inappropriate uses of shash and svec to use sset instead.
