treewide: Replace perror() calls with calls to logging functions

Browse source 
perror() prints directly to standard error, but in many cases standard
error might be already closed, or we might want to skip logging, based
on configuration. Our logging functions provide all that.

While at it, make errors more descriptive, replacing some of the
existing basic perror-style messages.
