Paolo Bonzini 758e5de501 bsd-user, linux-user: introduce qemu_process_cpu_events 
Add a user-mode emulation version of the function.  More will be
added later, for now it is just process_queued_cpu_work.

Paolo Bonzini 9cf342b491 accel/tcg: create a thread-kick function for TCG 
Round-robin TCG is calling into cpu_exit() directly.  In preparation
for making cpu_exit() usable from all accelerators, define a generic
thread-kick function for TCG which is used directly in the multi-threaded
case, and through CPU_FOREACH in the round-robin case.

Use it also for user-mode emulation, and take the occasion to move
the implementation to accel/tcg/user-exec.c.

Richard Henderson e6b7635c9a linux-user: Standardize on ELF_MACHINE not ELF_ARCH 
PowerPC was the one outlier that defined both ELF_ARCH and
ELF_MACHINE; ELF_ARCH was defined incorrectly, necessitating
the definition of elf_check_arch.

However, the elf file header field in question is called
e_machine, so ELF_MACHINE is in fact the better name.

Mechanically change most target/target_elf.h files,
then adjust ppc/target_elf.h manually.

Do not provide a default for ELF_MACHINE.
