getdents64() with wrapper over kern_getdirentries().

The patch was originally written by emaste@ and then adapted by trasz@
and me.

Note:
1. I divided linux_getdents() and linux_readdir() as in case when the
getdents() called with count = 1 (readdir() case) it can overwrite
user stack (by writing to user buffer pointer more than 1 byte).

2. Linux returns EINVAL in case when user supplied buffer is not enough
to contain fetched dirent.

3. Linux returns ENOTDIR in case when fd points to not a directory.

All this code is based on assumption that data will be stored in one piece,
and since buffer size if known and fixed, it is easier to hardcode it.

This patch adds a new function to the server krpc called
svcpool_close().  It is similar to svcpool_destroy(), but does not free
the data structures, so that the pool can be used again.

This function is then used instead of svcpool_destroy(),
svcpool_create() when the nfsd threads are killed.

Define them as RLIM_INFINITY.  This is allowed by POSIX in case all
resource limits are representable in an object of type rlim_t.  Since
we do not allow negative rlim_t, with some strength this definition is
conforming.

We are not conforming fully still because POSIX requires rlim_t to be
unsigned type.  Fixing this without breaking ABI to redefine
RLIM_INFINITY is impossible.

Since locks are dropped when a thread suspends, it's possible for another
thread to deliver a signal to the suspended thread. If the thread awakens from
suspension without checking for signals, it may go to sleep despite having
a pending signal that should wake it up. Therefore the suspension check is
done first, so any signals sent while suspended will be caught in the
subsequent signal check.

In general case m_pullup() does not really guarantee any data alignment.
Instead of depenting on side effects caused by data being always copied
out of mbuf cluster (which is probably a bug by itself), always allocate
aligned BHS buffer and read data there directly from socket.

While there, reuse new icl_conn_receive_buf() function to read digests.
The code could probably be even more optimized to aggregate those reads,
but until that done, this is still easier then the way it was before.

There could be a race between the vm daemon setting RACCT_RSS based on
the vm space and vmspace_exit (called from exit1) resetting RACCT_RSS to
zero.  In that case we can get a zombie process with non-zero RACCT_RSS.
If the process is jailed, that may break accounting for the jail.
There could be other consequences.

Fix this race in the vm daemon by updating RACCT_RSS only when a process
is in the normal state.  Also, make accounting a little bit more
accurate by refreshing the page resident count after calling
vm_pageout_map_deactivate_pages().
Finally, add an assert that the RSS is zero when a process is reaped.
