Since the previous patch, net_init now exposes some errors, so check for
them.

This driver interferes with other sandbox tests since it causes log output
to be interspersed with "No ethernet found." messages. Disable this driver
by default.
Enable it for the syslog tests so that they still pass.

At present there is no way to disable a log driver. But the syslog driver
causes (attempted) network traffic in sandbox every time a log message
is printed, which is often.
Add a flag to enable a log driver. Adjust struct log_device to use a short
for next_filter_num so that no more memory is used for devices. Also fix
a missing line in the struct log_driver comment while here.
To maintain compatibility, enable it for all drivers for now.

When a message is written by a log driver (e.g. via the network stack) this
may result in the generation of further messages. We cannot allow these
additional messages to be emitted as this might result in an infinite
recursion.
Up to now only the syslog driver was safeguarded. We should safeguard all
log drivers instead.

Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.
Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

Provide a log driver that broadcasts RFC 3164 messages to syslog servers.
rsyslog is one implementation of such a server.
The messages are sent to the local broadcast address 255.255.255.255 on
port 514.
The environment variable log_hostname can be used to provide the HOSTNAME
field for the messages. The optional TIMESTAMP field of RFC 3164 is not
provided.
