Subject: Avoid writing configuration to non-regular files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Check whether the configuration file (after symlink resolution) is
writable and is a regular file on htop startup, and only then, write the
configuration on exit.

Also permit reading when the legacy configuration file ("~/.htoprc") is
a symlink. Write the new configuration only when both the legacy file
and the new location are writable.

Thanks to Christian Göttsche (@cgzones) for providing the initial
version of the patch.

Fixes: #1426
