Description

exec: store parent directory and hardlink name of the binary in struct proc

While doing it, also move all the code to resolve pathnames and obtain
text vp and dvp, into single place. Besides simplifying the code, it
avoids spurious vnode relocks and validates the explanation why
a transient text reference on the script vnode is not harmful.
