Jason Volk d9a4f06bf6 ircd: Employ namespace scope extensions from c++1z/gnu++14. 
This is not a move to c++17. If the compiler happens to have support
for c++17 namespace scope resolution, they have been kind enough to
backport it to gnu++14. This limits our support for really old c++14
compilers, but that was limited anyway. GCC 6.1 and clang 3.6 tested.
