libpthread: Move namespacing include to top of .c files.

Stuff like libc's namespace.h, or atomic_op_namespace.h, which does
namespacing tricks like `#define atomic_cas_uint _atomic_cas_uint',
has to go at the top of each .c file.  If it goes in the middle, it
might be too late to affect the declarations, and result in compile
errors.

I tripped over this by including <sys/atomic.h> in mips
<machine/lock.h>.

(Maybe we should create a new pthread_namespace.h file for the
purpose, but this'll do for now.)

Always include a 1MB guard area beyond the end of stack. While ASLR will
normally create a guard area as well, this provides a deterministic area
for all binaries.
Mitigates the rest of CVE-2017-1000374 and CVE-2017-1000375 from
Qualys.
Revert for the moment, creates problems on i386.
Recommit exec_subr.c revision 1.79:
  Always include a 1MB guard area beyond the end of stack. While ASLR will
  normally create a guard area as well, this provides a deterministic area
  for all binaries.
  Mitigates the rest of CVE-2017-1000374 and CVE-2017-1000375 from
  Qualys.
Additionally, change VM_DEFAULT_ADDRESS_TOPDOWN to include
user_stack_guard_size in the size reservation.
Update VM_DEFAULT_ADDRESS32_TOPDOWN to include guard area.
Export the guard size of the main thread via vm.guard_size. Add a
complementary writable sysctl for the initial guard size of threads
created via pthread_create. Let the existing attribut accessors do the
right thing. Raise the default guard size for threads to 64KB.
