read_xpm: strengthen error handling.
The following cases are detected:
* attempt to read first line fails (observed in PNG images mislabeled as XPM)
* image file has XPM2 header
* image file lacks XPM3 header (observed in SVG images mislabeled as XPM)
* failed to read all HEIGHT pixel lines (observed mismatch between stated
and actual number of lines; do not attempt to recover, just report error)
