[OpenAFS] Retiring the LWP fileserver

Cases I knew of LWP fileserver being used:
Linux with "new" pthreads support until what turned out to be bugs in
our pthread support
were addressed. LD_ASSUME_KERNEL also could be used at the time to
"assume" an older kernel
and assume LinuxThreads.
Previous NetBSD versions: their pthread support was buggy.

As far as I know, the LWP fileserver (nor volserver) are neither
necessary nor desirable anywhere.
