vfs_fruit: don't open basefile in ad_open() and simplify API

We never need an fd on the basefile when operating on the metadata, as
we can always use path based syscalls. Opening the basefile conflicts
with "kernel oplocks" so just don't do it.

Additional changes:

- remove the adouble_type_t argument to ad_open(), the type is passed
  and set when allocating a struct adouble with ad_alloc()

- additionally pass an optional fsp to ad_open() (so the caller can pass
  NULL). With this change we can move the fd inheritance from fsp to ad
  into ad_open() itself where it belongs and remove it from the caller

util: pidfile_pid() should not unlink PID file

This causes a race.  If 2 callers to pidfile_create() both a find a
stale PID file using pidfile_pid().  The 1st may then return to
pidfile_create() and create a new PID file, which can then be unlinked
by the 2nd caller.

Consequently, PID file creation can not depend on creating the file,
so drop O_EXCL from the call to open().

The code to check for the 'repsFrom' highwatermark didn't have any

Using a zero HWM probably wouldn't have impacted functionality because
we were still correctly using the uptodatenessvector, which should
avoid a full replication.
