Juraj Lutter (otis@) reported a panic "dvp != vp not true" in
cache_enter_time() called from the NFS client's nfsrpc_readdirplus()
function.
This is specific to an NFSv3 mount with the "rdirplus" mount
option. Unlike NFSv4, NFSv3 replies to ReaddirPlus
includes entries for the current directory.

This trivial patch avoids doing a cache_enter_time()
call for the current directory to avoid the panic.

for the which which definitely use membar to sync with interrupt handlers.

libc and rtld uses of __compiler_membar() seems to want compiler barriers
proper.

The barrier in sched_unpin_lite() after td_pinned decrement seems to be not
needed and removed, instead of convertion.

This should return -1 with OTHER/ENOMEM set in the handle when malloc
fails, like everywhere else in libifconfig.

It happens to trip over an assert but does not matter for correctness at
this time. However, do it for future proofing.

Historically it was allowed for any names, but arguably should never be
even attempted. Allow it again since there is a release pending and
allowing it is bug-compatible with previous behavior.

MAX_SNAPSHOT_VMNAME is a macro used to set the size of a character
buffer that stores a filename or the path to a file - this file is used
by the save/restore feature.

Since the file doesn't have anything to do with a vm name, rename
MAX_SNAPSHOT_VMNAME to MAX_SNAPSHOT_FILENAME. Bump the size to PATH_MAX
while here.

Combine send_start_checkpoint() and send_start_suspend() into a
single function named snapshot_request().

snapshot_request() is equivalent to send_start_checkpoint() and
send_start_suspend() except that it takes an additional argument. The
additional argument, enum ipc_opcode, is used to determine the type of
snapshot request being performed. Also, switch to using strlcpy instead
of strncpy.

Generalize the naming here since the domain socket that uses these codes
might be used for purposes other than the save/restore feature.

- rename checkpoint_opcodes to ipc_opcode
