SFP matching is done by in order:
-vendor name, part number, serial
-vendor name, part number
-part number

If .config's entry (i.e. serial) is not empty match will happen only with
specific serial.

Additionally:
-Change default defines in Kconfig
-Update user manual with matching info
-Remove entry from wrs-todo about matching SFP vendor

fiber-specific alpha values.  Use in the next commits.

This commit adds port parameters to Kconfig, using the same
values we currently have in wrsw_hal.conf (i.e: tx delay = 0,
rx delay = 160000 or 161200).

These values are used in later commits, where this dot-config
stuff is replacing wrsw_hal.conf.  The "role=" and "fiber=" values
will be used later, but I'd better write them now to avoid
excessive edits to this file.

PPSi is not optional, so change Kconfig in order not to run the question.

Also, rename "Local" to "Local Network" configuration.

Now /etc/init.d/S20dot-config is able to download a new dot-config
file if the user specified an URL at configuration time.

We support tftp, http and ftp.  Full documentation in next commit.

If static IP addressing is used (e.g. using wrboot), it makes sense
to provide a static DNS nameserver.  This option may be useful to
people building a single image to install several switches.

If the configuration string is empty (default) nothing changes (and
/etc/resolv.conf is a symlink to /tmp/resolv.conf, so a dhcp client
can work withint a read-only filesystem).

At configuration time, before building, users can select
the ntpserver to be used to prime WR time at boot.  By default
no server is queried.

Developers may want to preserve the filesystem image, to verify the
effect of configuration options, avoiding the need to untar
images/wrs-image.tar.gz every time.

I personally used it to verify the next commits, other people may
prefer to keep it disabled.

The PPSi daemon can now be selected in Kconfig. This commit
changes configuration and the build scripts to support either of them.

Both the buildroot and busybox config files are not hosted in
configs/buildroot/ within wr-switch-sw, where I expect to place
several such configuration files, at least to try different setups.

The name of the buildroot configuration file is not chosen using
Kconfig (but the default is silently applied.  If the user
provides a relative pathname, it is expanded to
wr-switch-sw/configs/buildroot .
