Information is tracked inside the TCGContext structure, and later used
by tracing events with the 'tcg' and 'vcpu' properties.
The 'cpu' field is used to check tracing of translation-time
events ("*_trans"). The 'tcg_env' field is used to pass it to
execution-time events ("*_exec").

Fix races between signal handling and the pause syscall by
reimplementing it using block_signals() and sigsuspend().
(Using safe_syscall(pause) would also work, except that the
pause syscall doesn't exist on all architectures.)

Without this a signal could vanish on thread exit.

If there is a signal pending during fork() the signal handler will

host_to_target_siginfo() is implemented by a combination of
host_to_target_siginfo_noswap() followed by tswap_siginfo().
The first of these two functions assumes that the target_siginfo_t

This patchset overhauls the linux-user signal handling code to
fix a number of race conditions. It is essentially a v2 of

because it can take too long.
Run it with "make docker-travis@ubuntu".

"requires" checks the "FEATURE" environment for specified prerequisits,
and skip the execution of test if not found.
"build_qemu" is the central routine to compile QEMU for tests to call.
