Often lustre file systems will employ LNet routers in their
set ups. Those routers tend to be very light weight so we want
to avoid installing additional software that will burden the
system. Installing the entire lustre client can be pretty heavy
so we want to give the ability to only enable the LNet stack for
the routers which is all that is needed anyways. This patch series
allows that option for users of the upstream client.

The lustre file system has a layered architecture with
libcfs as the lowest layer and LNet layered on top. Then
on top of LNet we run the lustre client. This patch moves
the libcfs module code out of lustre into the lnet tree.
This fits into the long term goal of eventually merging
libcfs into LNet.

A few errors exist for the Kconfig option LNET_MAX_PAYLOAD. First
mistake is the default size is 1MB not 2MB as it is shown to the
person configuring the kernel. Second the LNET_MAX_PAYLOAD option
is more closely related to LNET than the LUSTRE_FS option.

In the case of lustre routers you only need a functioning
LNet stack. Especially since often the routers are very
light weight and want to avoid any addition software that
would create additional pressures on the system.
