installs clang as /usr/bin/cc, /usr/bin/c++ and /usr/bin/cpp.
Note this does *not* disable building and installing gcc, which will
still be available as /usr/bin/gcc, /usr/bin/g++ and /usr/bin/gcpp. If
you want to disable gcc completely, you must use WITHOUT_GCC.

This is harmless because srandom() is called somewhere else, with time(NULL)
as a seed, but this is more correct.

operations for setting and accessing vnode's v_socket field.
The operations are necessary to implement proper unix socket handling
on layered file systems like nullfs(5).
This change fixes the long standing issue with nullfs(5) being in that
unix sockets did not work between lower and upper layers: if we bound
to a socket on the lower layer we could connect only to the lower
path; if we bound to the upper layer we could connect only to the
upper path. The new behavior is one can connect to both the lower and
the upper paths regardless what layer path one binds to.

instead of accepting half-constructed vnode. Previous code cannot decide
what to do with such vnode anyway, and although processing it for hash
removal, paniced later when getting rid of nullfs reference on lowervp.
While there, remove initializations from the declaration block.

function null_destroy_proto() from null_insmntque_dtr(). Also
apply null_destroy_proto() in null_nodeget() when we raced and a vnode
is found in the hash, so the currently allocated protonode shall be
destroyed.
Lock the vnode interlock around reassigning the v_vnlock.
In fact, this path will not be exercised after several later commits,
since null_nodeget() cannot take shared-locked lowervp at all due to
insmntque() requirements.

Enforce a boundary of no more than 4GB - transfers crossing a 4GB
boundary can lead to data corruption due to PCIe limitations. This
change is a less-intrusive workaround that can be quickly merged back
to older branches; a cleaner implementation will arrive in HEAD later
but may require KPI changes.
This change is based on a suggestion by jhb@.
