76cf7d7e54 Implement a mechanism for making changes in the kernel<->driver PPS
interface without breaking ABI or API compatibility with existing drivers.

The existing data structures used to communicate between the kernel and
driver portions of PPS processing contain no spare/padding fields and no
flags field or other straightforward mechanism for communicating changes
in the structures or behaviors of the code.  This makes it difficult to
MFC new features added to the PPS facility.  ABI compatibility is
important; out-of-tree drivers in module form are known to exist.  (Note
that the existing api_version field in the pps_params structure must
contain the value mandated by RFC 2783 and any RFCs that come along after.)

These changes introduce a pair of abi-version fields which are filled in
by the driver and the kernel respectively to indicate the interface
version.  The driver sets its version field before calling the new
pps_init_abi() function.  That lets the kernel know how much of the
pps_state structure is understood by the driver and it can avoid using
newer fields at the end of the structure that it knows about if the driver
is a lower version.  The kernel fills in its version field during the init
call, letting the driver know what features and data the kernel supports.

To implement the new version information in a way that is backwards
compatible with code from before these changes, the high bit of the
lightly-used 'kcmode' field is repurposed as a flag bit that indicates the
driver is aware of the abi versioning scheme.  Basically if this bit is
clear that indicates a "version 0" driver and if it is set the driver_abi
field indicates the version.

These changes also move the recently-added 'mtx' field of pps_state from
the middle to the end of the structure, and make the kernel code that uses
this field conditional on the driver being abi version 1 or higher.  It
changes the only driver currently supplying the mtx field, usb_serial, to
use pps_init_abi().

79de2555b1 Rework PRIVATELIB
Now when a lib is marked as PRIVATELIB it is renamed into libprivate$foo instead
of being installed in /usr/lib/private and playing with rpath.

Also allow to install headers for PRIVATELIBS in that case the headers will be
installed in /usr/include/private/$foo

Keep the headers under a private namespace to prevent third party build system
to easily find them to ensure they are only used on purpose.

This allows for non base applications to statically link against a library in
base which is linked to a privatelib

Treating PRIVATELIBS as regular libraries allows to push them into our current
compatX packages if needed.

While here finish promotion of libevent as PRIVATELIB
Install header for bsdstat and libucl

c8296a2c95 Various updates to the ftruncate(2) documentation:
- Note that ftruncate(2) can operate on shared memory objects and cross
  reference shm_open(2).
- Note that ftruncate(2) does not change the file position pointer (aka
  seek pointer) of the file descriptor.
- ftruncate(2) will fail with EINVAL for all sorts of other fd types than
  just sockets, so instead note that it fails for all but regular files and
  shared memory objects.
- Note that ftruncate(2) also appeared in 4.2BSD along with truncate(2).
  (Or at least the manpage for both appeared in 4.2, I did not check the
  kernel code itself to see if either predated 4.2.)

128603d747 Remove old iv_bss entry from the node table
This may happen on RUN -> SCAN -> RUN -> SCAN state transition:

1. RUN -> SCAN: in ieee80211_sta_join1(): iv_bss will be moved to obss,
   refcnt will be reduced by 2 (default minimum).

Now, if old iv_bss have some extra references (for example, from
unacknowledged probe responses), it will not be freed and will stay
in the node table.

2. SCAN -> RUN.

3. If old iv_bss will not be deleted by the time when the next RUN -> SCAN
   state transition occurs, then sta_leave() will reduce it's reference
   counter once more. As a result, two last users will free it -> this will
   lead to kernel panic.

In this patch old iv_bss entry is explicitly removed from the node table in
ieee80211_sta_join1() (as a result, it will not be processed by sta_leave()).
