mount_9p: don't cache path names by default

Caching path names doesn't handle file changes by host, which is
not expected for normal usages.  So turn it off by default.

Instead, -C option is added to turn it on.

Patch from k-goda@IIJ with my tweaks

Support optional square brackets around the host name.

The brackets are required when using numeric IPv6 addresses as they
contain colons as part of their syntax.  We do not enforce that the
thing in the brackets is a numeric IPv6 address - this matches scp
syntax and behavior.

mount_9p: add initial support for 9P2000.u

The implementation enables to work with a server talking 9P2000.u.  However, it
doesn't use the extended fields yet; it just ignores those of received messages
and sets "please ignore" values to those of sending messages such as zero-length
strings and maximum unsigned values.

The feature is enabled by the -u option.

Pull the daemonizing code out of the library mainloop into the file

Alter the strategy for reading/writing a bit.  First of all, use
PUFFS_KFLAG_WTCACHE.  Second, create separate fids for reading and
writing.  If opening for read, open a read-only fid and for write
a write-only fid; use these for reading and writing.  When the
open-count for a node drops to zero, clunk both.  This avoids hitting
the fid limit when accessing large directory hierarchies.

Two problems remain:
* does not take credentials into account, although we can only mount
  the remote 9P file server with one set of credentials, so not a
  huge worry
* doesn't work for the open/mmap/close/access_memory_window case, but
  that will require some further kernel changes

mount_9p: mount a file server using the Plan9 file sharing protocol

Works, but lots of little things to nibble on:
* fix permissions to work better
* limit the amount of open files required
* do constant folding with psshfs code
* support authentication
etcetc.
