Return to ssherr.h CVS log

Up to [local] / src / usr.bin / ssh

improve the error message for u2f enrollment errors by making
ssh-keygen be solely responsible for printing the error message and
convertint some more common error responses from the middleware to
a useful ssherr.h status code. more detail remains visible via -v
of course.

also remove indepedent copy of sk-api.h declarations in sk-usbhid.c
and just include it.
