libc: Pacify lint on aarch64.

Add the fpset* routines for tests

_REG_LR should be _lwp_exit

need to set _UC_TLSBASE of uc_flags for _lwp_makecontext().
pointed out from skrll@. thanks.

Fix the lib/libc/setjmp/t_setjmp:{,_}longjmp_zero test cases

Don't futz with tpidr_el0 in {set,long}jmp as it breaks TLS as seen in
qemu

branches: 1.3.6;
fix to work
* no need to check x29 != NULL. fp may be NULL.
* don't break in-use register x5.

libc: Pacify lint on aarch64.

don't use systm.h header, it's not available to userland.

as a side effect, this fixes the evbarm64 build, which was failing due
to a declaration of psize_t physmem in systm.h, while psize_t is
kernel-only.

ok riastradh

branches: 1.1.2;
Some test programs require these.

Fix __siglongjmp14().

Fixes SIGINT causing ksh to "longjmp botch", presumably due to incorrect
magic number.
