* New abbreviated types are in osd and util namespaces, and also in global namespace for things that #include "emu.h" * Get rid of import of cstdint types to global namespace (C99 does this anyway) * Remove the cstdint types from everything in emu * Get rid of U64/S64 macros * Fix a bug in dps16 caused by incorrect use of macro * Fix debugcon not checking for "do " prefix case-insensitively * Fix a lot of messed up tabulation * More constexpr * Fix up many __names
