Warner Losh da07e6944f bsd-user/sysarch: Move to using do_freebsd_arch_sysarch interface
do_freebsd_arch_sysarch() exists in $ARCH/target_arch_sysarch.h for x86.
Call it from do_freebsd_sysarch() and remove the mostly duplicate
version in syscall.c. Future changes will move it to os-sys.c and
support other architectures.

Warner Losh 381c42a186 bsd-user: remove sparc and sparc64
These are broken here and in the bsd-user fork. They won't be fixed as
FreeBSD has dropped support for sparc. If people wish to support this in
other BSDs, you're better off starting over than starting from these
files.

Alex Bennée f7e68c9c99 tcg/plugins: implement a qemu_plugin_user_exit helper
In user-mode emulation there is a small race between preexit_cleanup
and exit_group() which means we may end up calling instrumented
instructions before the kernel reaps child threads. To solve this we
implement a new helper which ensures the callbacks are flushed along
with any translations before we let the host do it's a thing.

While we are at it make the documentation of
qemu_plugin_register_atexit_cb clearer as to what the user can expect.

Emilio G. Cota c36f7a642c *-user: plugin syscalls
To avoid too much duplication add a wrapper that the existing trace
and the new plugin calls can live in. We could move the -strace code
here as well but that is left for a future series as the code is
subtly different between the bsd and linux.

Lluís Vilanova 9c15e70086 trace: [*-user] Add events to trace guest syscalls in syscall emulation mode
Adds two events to trace syscalls in syscall emulation mode (*-user):

* guest_user_syscall: Emitted before the syscall is emulated; contains
  the syscall number and arguments.

* guest_user_syscall_ret: Emitted after the syscall is emulated;
  contains the syscall number and return value.

Ed Maste e6a3ee5f79 bsd-user: OS-agnostic 64-bit SYSCTL types
Use existence of type as #ifdef condition rather than FreeBSD-specific
version check, as suggested by Patrick Welche.

Also handle the signed (CTLTYPE_S64) case identically to the unsigned
(CTLTYPE_U64) case, per later patches in the FreeBSD ports tree
(emulators/qemu-devel/files/patch-z-arm-bsd-user-001).
