The `g_file_info_get_content_type` function is used, but the content
type attribute is not requested. Consequently, several critical warnings
are printed. Let's add the content type attribute to the list of
requested attributes.

Fixes: #734

The network backend relies on the fact that the content type attribute is
always set. This is not true for files from wsdd backend, which leads to
critical warnings. Let's always set the content type attribute to avoid
that.

The `g_stat` result is not checked currently. This might lead to the
"Conditional jump or move depends on uninitialised value(s)" errors
detected by the valgrind tool. Let's check the result first before
using the `statbuf` data.

With IPv6, the passive mode data connection address is constructed by
taking the control socket address and replacing the port with the one
specified in the EPSV response. In doing so, we lose the scope-id and
flowinfo properties. The scope-id field in particular is required when
connecting to a link local address, as it determines which link the
address belongs to. Without it, the connection fails.

To fix this, manually construct the GInetSocketAddress instance, copying
all the fields except the port from the old address.

When the `GVFS_DEBUG` envar is set, list of discovered devices is printed
on each reload i.e. each 15 seconds currently. This spamming is unwanted.
Let's print this info only if the `GVFS_WSDD_DEBUG` envar is set.
