Description of problem by nalin(a)redhat.com:
Various functions in the directory server are declared with extern "C"
linkage, causing the compiler to emit references to an unmangled symbol
name, but because their definitions don't match the declarations, and
the definitions are compiled using the C++ compiler, the implementations
are emitted as mangled symbols.
Fix description: Adjusted the function declaration to the implementation.
Additionally, removed unused macros for ACL_ReadDbMapFile, which had been
removed.
