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.)

Use the pta_magic field in pthread attribute

Set PT_ATTR_DEAD on pthread_attr_destroy().
Check pta_magic before using pthread_attr_t in a bunch of other functions.

pthread__attr_init_private:
malloc+memset -> calloc. Also initialize all values to the proper
defaults.
This fixes the "rustc panic" discussed on pkgsrc-users.

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.

Separate pthread_t from thread stack. Drop additional alignment
restrictions on the thread stack. Remove remaining parts of stackid.

move namespace protection before inclusion.

Add a weak alias for pthread_attr_get_np. Noted my Matthias Drochner.

Add pthread_getattr_np()

fix -Wsign-compare issues

pthread_attr_getschedparam: allow without preceding setparam on the
attr structure.

Now that we have all the scheduling gunk, make these do something useful:

pthread_attr_get_np
pthread_attr_setschedparam
pthread_attr_getschedparam
pthread_attr_setschedpolicy
pthread_attr_getschedp

pthread_attr_setstacksize: EINVAL if the requested size is less than
sysconf(_SC_THREAD_STACK_MIN).

Remove clause 3 and 4 from TNF licenses

add missing static decls.

Remove PT_FIXEDSTACKSIZE_LG.

pthread_attr_getschedpolicy() wasn't setting the return buffer at all.
SCHED_OTHER happens to be 0, so this assignment to "int *" succeeds,

pthread_attr_getschedpolicy() wasn't setting the return buffer at all.
SCHED_OTHER happens to be 0, so this assignment to "int *" succeeds,
and becomes a no-op.

Fix by dereferencing "policy" to do the assignment, thus filling the
return buffer with 0.

Implement pthread_attr_{set,get}schedpolicy() at the same level as the other
scheduling stuff: only handle SCHED_OTHER. Like the rest of the scheduling

Add:

int pthread_attr_setcreatesuspend_np(pthread_attr_t *);
int pthread_suspend_np(pthread_t);
int pthread_resume_np(pthread_t);

needed for java. Approved and fixed by cl.

sprinkle ARGSUSED for good cheer.

pthread.c was getting a bit unwieldly. Move pthread_attr stuff out
into a new file, and put the shared private structure definition in
pthread_int.h.
