prevent psignal/psiginfo from clobbering stderr orientation, errno
these functions are specified to write to stderr but not set its
orientation, presumably so that they can be used in programs operating
stderr in wide mode. also, they are not allowed to clobber errno on
success. save and restore to meet the requirement.
psiginfo is reduced to a think wrapper around psignal, since it
already behaved the same. if we want to add more detailed siginfo
printing at some point this will need refactoring.
