It is a more standard name...

If system-installed rpcgen if such exists.
If none is found, build our own.
Override with
   ./configure --with-rpcgen=internal
for internal rpcgen or
   ./configure --with-rpcgen=/local/rpcgen
for a non-standard location.

Also fix a few bugs that came up in initial testing.

Some versions of libblkid have a terrible memory leak which makes
mounted grow toooo big.  So support
   --disable-uuid
to remove the uuid functionality and liblkid with it.

Ultimately it makes sense to remove remove rpcgen from the nfs-utils
release as it is already in the glibc release.  With this patch
you can use the system rpcgen to make sure it works.
It is not default yet, but it might be in a future release.

We don't need it (any more).
Also add AM_PROG_CC_C_O as we seem to need it..

rather than explicit -D_FILE_OFFSET_BITS=64

Taken from Redhat -5 sources.

If statd is not running (/var/run/rpc.statd.pid) when an nfs filesystem
is mounted (v2 or v3, with remote locking enabled), and if
/usr/sbin/start-statd (or other program specified at config time) is
present, then run that program to start statd.

This means that statd does not need to be running "just in case".
It only needs to be started at boot time if the nfs server is
started.

i.e. you now need --disable-secure-statd if you want any client
other than lockd to talk to statd.

Also relax the RESTRICTED_STATD checks so that a recent kernel
with /proc/sys/fs/nfs/nsm_use_hostnames set can still talk to
statd.

Finally, restrict access to simulate_crash so that only privileged
processes on localhost can call it.  Having it accessible by the
whole world is probably not much more than a minor inconvenience,
but it really should be kept closed.

This was only needed for kernels 2.2.14 through 2.2.17.

These have long since been superceded, so remove some dead weight.
