///////////////////////////////////////////////////////////////////////////////
//
// IRCd's namespacing is as follows:
//
// IRCD_     #define and macro namespace
// RB_       #define and macro namespace (legacy, low-level)
// ircd_     C namespace and demangled bindings
// ircd::    C++ namespace
//

///////////////////////////////////////////////////////////////////////////////
//
// Standard includes
//
// This header includes almost everything we use out of the standard library.
// This is a pre-compiled header. Project build time is significantly reduced
// by doing things this way and C++ std headers have very little namespace
// pollution and risk of conflicts.
//
// * If any project header file requires standard library symbols we try to
//   list it here, not in our header files.
//
// * Rare one-off's #includes isolated to a specific .cc file may not always be
//   listed here but can be.
//
// * Third party / dependency / non-std includes, are NEVER listed here.
//   Instead we include those in .cc files, and use forward declarations if
//   we require a symbol in our API to them.
