MFC r208453:
Reorganize syscall entry and leave handling.
Implement ptrace_lwpinfo pl_flags PL_FLAG_SCE, PL_FLAG_SCX and
PL_FLAG_EXEC.

The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are
changed to use syscallenter()/syscallret(). MIPS and arm are not
converted and use the mostly unchanged syscall() implementation.

MFC r208514:
Change ia64' struct syscall_args definition so that args is a pointer to
the arguments array instead of array itself.

MFC r208566:
Allow to use syscallname(9) outside subr_trap.c.

MFC r209258 (by rpaulo):
Make DTrace syscall provider work again by including opt_kdtrace.h here.

MFC r209313:
Only enable kdtrace hook in the LINT on the architectures that implement it.

MFC r209697:
Obey sv_syscallnames bounds in syscallname().

NOTE: The KBI of the struct sysentvec is changed, new required members
sv_set_syscall_retval, sv_fetch_syscall_args and sv_syscallnames are
added. The sv_prepsyscall field is now ignored. Third-party modules
using the struct sysentvec must be modified and recompiled, we believe
that only ABI emulators are affected. No such out-of-tree modules are
known. In-tree modules that are affected by the change were converted
to depend on exact version of the kernel, see r214421.
