a9eaaccd22 storage: Fix volStorageBackendRBDRefreshVolInfo function return errors
Fix the return value status comparison checking for call to
volStorageBackendRBDRefreshVolInfo introduced by commit id f46d137e.

we only should fail when the return is < 0. -ENOENT, -ETIMEDOUT will
ignore according commit id f46d137e.

cdd362e0e7 storage: escape ipv6 for ceph mon hosts to librados
Hosts for rbd are ceph monitor daemons. These have fixed IP addresses,
so they are often referenced by IP rather than hostname for
convenience, or to avoid relying on DNS. Using IPv4 addresses as the
host name works already, but IPv6 addresses require rbd-specific
escaping because the colon is used as an option separator in the
string passed to librados.

Escape these colons, and enclose the IPv6 address in square brackets
so it is distinguished from the port, which is currently mandatory.

array of strings in a single buffer instead of an array. It is

code out into a separate method.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.
