[PATCH 0/7] Simplify complaints and symbol-reading output

[Tom Tromey <tom at tromey dot com>]

This series cleans up symbol-reading output and simplifies complaints
a bit more.  I've long thought the current output was difficult to
read, and in some cases actively confusing; this series is another
attempt to fix this up.  (The previous attempt involved adding
progress metering.)

This was regression tested by running it through a couple of the
buildbot builders.
