The capsicum signal stuff is new with FreeBSD 14, rev 1400026, so only
define QEMU_SI_CAPSICUM there. Only copy _capsicum when QEMU_SI_CAPSICUM
is defined. Default to no info being passed for signals we make no guess
about.

Implement the meat of the sigaction(2) system call with do_sigaction and
helper routiner block_signals (which is also used to implemement signal
masking so it's global).

Implements the meat of a sigreturn(2) system call via do_sigreturn, and
helper reset_signal_mask. Fix the prototype of do_sigreturn in qemu.h
and remove do_rt_sigreturn since it's linux only.

Mirror the linux-user practice and add a si_type argument to queue
signal. This will be transported as the upper 8 bits in the si_type
element of siginfo so that we know what bits of the structure are valid
and so we can properly implement host_to_target_siginfo_noswap and
tswap_siginfo. Adapt the one caller of queue_signal to the new
interface. Use all the same names as Linux (except _RT which we don't
treat differently, unlike Linux), though some are unused. Place this
into signal-common.h since that's a better place given bsd-user's
structure. Move prototype of queue_signal to signal-common.h to mirror
linux-user's location.

Start to implement the force_sig_fault code. This currently just calls
queue_signal(). The bsd-user fork version of that will handle this the
synchronous nature of this call. Add signal-common.h to hold signal
helper functions like force_sig_fault.
