base: uniform base-internal header structure

This patch establishes a common organization of header files
internal to the base framework. The internal headers are located at
'<repository>/src/include/base/internal/'. This structure has been
choosen to make the nature of those headers immediately clear when
included:

  #include <base/internal/lock_helper.h>
