In CUPS 1.7 httpConnect() and httpConnectEncrypt() were deprecated and
replaced with httpConnect2(). This checks if httpConnect2() is available
and if so, replaces the uses of the deprecated functions.
In the CUPS source code, httpConnect() and httpConnectEncrypt() are now
wrappers around httpConnect2(), so we make sure to use the same
arguments as in the CUPS source code so the two code paths are sure to
be identical:

'device-class' property of PpPrintDevice can contain "network"
or "direct" values. This information can be stored in already
present property 'is-network-device' as well.

Add pp_host_get_lpd_devices_async() and
pp_host_get_lpd_devices_finish() functions to PpHost class.
pp_host_get_lpd_devices_async() starts searching for LPD printer
on given address.
The test consist in connection to the default port 515 (or the one
given by creator of PpHost) of the address and sending a print job
to it, which in turn returns a status (we test several standard
queue names).
We suppose that there is a LPD printer on the address if a buffer
with zero length is returned (rfc 1179 5.2).

Add pp_host_get_socket_devices_async() and
pp_host_get_socket_devices_finish() functions to PpHost class.
pp_host_get_socket_devices_async() starts searching for socket printer
on given address.
The test consist in connection to the default port 9100 (or the one
given by creator of PpHost) of the address.
We suppose that there is an AppSocket/HP JetDirect printer on the address
if the connection succeeds.

This commit adds PpHost object which represents a remote
host from which we want to get printers. It contains
asynchronous method for enumerating printers list from the host
using CUPS' SNMP backend and method for enumerating printers list
directly from the remote CUPS server running on the host. (#683229)
