Thomas Huth	2296b46556	common-user: Only compile the common user code if have_user is set 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).

Richard Henderson	620d0b49a4	common-user/host/sparc64: Fix safe_syscall_base Use the "retl" instead of "ret" instruction alias, since we do not allocate a register window in this function. Fix the offset to the first stacked parameter, which lies beyond the register window save area.

Paolo Bonzini	9d24fb73a1	meson: cleanup common-user/ build 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.

Richard Henderson	5bfd125ec8	common-user: Adjust system call return on FreeBSD FreeBSD system calls return positive errno. On the 4 hosts for which we have support, error is indicated by the C bit set or clear.

Richard Henderson	bbf15aaf7c	common-user: Move safe-syscall.* from linux-user 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.
