Updating overviews in existing .rrd file fails due to permissions

Description

Attempting to run: 

gdaladdo small.img 2

On the attached file fails. This appears to be because the .rrd file is opened in read-only mode even when gdaladdo opens the .img file in update mode.

In reviewing this situation I found that errors were not being propagated properly, nor reported nicely for this situation. I have applied r15114, r15113 and r15112 in trunk to improve the situation. None of these changes are critical though and I don't plan to take them into 1.5 branch. They also don't fix the core problem.

One more error propagation fix in r15115.

The actual fix - which opens the .rrd file with the same permissions as the master, is in trunk (r15117) and 1.5 branch (r15118).

A test has been added for this in the test suite (r15116).
