In OVS, we currently use the term 'facility' to mean the place
where we log (syslog, console or file). In Linux's syslog() and
rfc5424, the term 'facility' is used to specify what type of program
is logging the message (e.g: LOG_DAEMON). This causes confusion
while reading vlog's code. This commit changes the term 'facility'
to 'destination'.

A new function vlog_insert_module() is introduced to avoid using
list_insert() from the vlog.h header.

Typically an nl_sock client can stack-allocate the buffer for receiving
a Netlink message, which provides a performance boost.

This was useful for observing IFF_RUNNING change as I removed and inserted
cables.
(nlmon is a test utility that doesn't get installed.)

When this library was originally implemented, support for Linux 2.4 was
important. The Netlink implementation in Linux only added support for
joining and leaving multicast groups after a socket is bound as of Linux
2.6.14, so the library did not support it either. But the current version
of Open vSwitch targets Linux 2.6.18 and over, so it's fine to add this
support now, and this commit does so.
This will be used more extensively in upcoming commits.

The parts of the netlink module that are related to sockets are
Linux-specific, since only Linux has AF_NETLINK sockets. The rest can be
built anywhere. This commit breaks them into two modules, and builds the
generic one on all platforms.

Until now, the collection of vlog modules supported by a given OVS program
was not specific to that program. That means that, for example, even
though ovs-dpctl does not have anything to do with jsonrpc, it still has
a vlog module for it. This is confusing, at best.
This commit fixes the problem on some systems, in particular on ones that
use GCC and the GNU linker. It uses the feature of the GNU linker
described in its manual as:
If an orphaned section's name is representable as a C identifier then
the linker will automatically see PROVIDE two symbols: __start_SECNAME
and __end_SECNAME, where SECNAME is the name of the section. These
indicate the start address and end address of the orphaned section
respectively.
Systems that don't support these features retain the earlier behavior.
This commit also fixes the annoyance that modifying lib/vlog-modules.def
causes all sources files that #include "vlog.h" to recompile.

This is no longer necessary.

Since the timeval module now initializes itself on-demand, there is no
longer any need to initialize it explicitly, or to provide an interface to
do so.
