* do not move constant variables * applet_manager: avoid possible use after move * use constant references where pointed out by msvc * extra_hid: initialize response * ValidateSaveState: passing slot separately is not necessary * common: mark HashCombine as nodiscard * cityhash: remove use of using namespace std * Prefix all size_t with std:: done automatically by executing regex replace `([^:0-9a-zA-Z_])size_t([^0-9a-zA-Z_])` -> `$1std::size_t$2` based on 7d8f115 * shared_memory.cpp: fix log error format * fix compiling with pch off
