Merge changes made in Gnus trunk.

gnus-sum.el: Avoid calling a hook function per summary line;
Call `gnus-summary-highlight-line' directly from all places that used to call it indirectly.

netrc.el (netrc-credentials): New conveniency function.

gnus-start.el (gnus-read-active-file-1): If gnus-agent isn't set, then do request scans from the backends.
