2022-06-28common-user: Only compile the common user code if have_user is setThomas Huth
There is no need to waste cycles here if we only compile the system binaries or tools. Additionally, this change is even a hard requirement for building the tools on systems that do not have an entry in the common-user/host/ folder (since common-user/meson.build is trying to add such a path via the include_directories() command).

2022-01-12meson: cleanup common-user/ buildPaolo Bonzini
It is not necessary to have a separate static_library just for common_user files; using the one that already covers the rest of common_ss is enough unless you need to reuse some source files between emulators and tests. Just place common files for all user-mode emulators in common_ss, similar to what is already done for softmmu_ss in full system emulators. The only disadvantage is that the include_directories under bsd-user/include/ and linux-user/include/ are now enabled for all targets rather than only user mode emulators. This however is not different from how include/sysemu/ is available when building user mode emulators.

2021-12-20common-user: Move safe-syscall.* from linux-userRichard Henderson
Move linux-user safe-syscall.S and safe-syscall-error.c to common-user so that bsd-user can also use it. Also move safe-syscall.h to include/user/. Since there is nothing here that is related to the guest, as opposed to the host, build it once.
