Replace afterinstall: hack with FILES mechanism.

Use SHAREOWN/SHAREMODE/SHAREGRP rather than LIB* as these are plain ASCII

support for Raspbetty Pi 2 in stable/10.
An IPI must be cleared before it is handled otherwise next IPI could be
missed. In other words, if a new request for an IPI is sent while the
previous request is being handled but the IPI is not cleared yet, the
clearing of the previous IPI request also clears the new one and the
handling is missed.
There are only three MP interrupt controllers in ARM now. Two of them are
fixed by this change, the third one is correct, probably only just by
accident. The fix is minimalistic as new interrupt framework is awaited.
It was debugged on RPi2 where missing IPI handling together with SCHED_ULE
led to situation in which tdq_ipipending was not cleared and so IPI_PREEMPT
was stopped to be sent. Various odditys were found related to slow system
response time like various events timed out, and slow console response.

Update svnlite from 1.8.10 to 1.8.14, and the support components:
serf->1.3.8, apr->1.5.2, apr-util->1.5.4, sqlite3->3.8.11.1
This includes syncing the developer templates with head.
Add support for Fresco Logic USB 3.0 host controller.
Fresco Logic hosts advertise MSI, but fail to actually generate MSI
interrupts. We have to disable MSI use.

The latest version of lex requires the latest m4 to build, add a dependency
when running the build-tools stage.
The requirement is due to the -P flag used when running m4 from usr.bin/lex
Makefile to generate skel.c. With the old m4 that fails and the failure is
ignored, resulting in an empty(-ish) skel.c, which leads to later build
failures when the misconfigured new lex tool is run.
This enables building -current (and 10-stable after MFC) on a stable-8
system again.
fmake does not have :tW, so use some clever :Q tricks to achieve the
same result. This won't work if PATH actually contains spaces, but
it's better than not working at all.
The top-level Makefile.inc1 uses 'make -C release -V' to lookup revision
information, which causes Makefile.vm and Makefile.vagrant to be included.
fmake has 2 issues here:
1. It doesn't like the empty result of .if ${VAR:Mfoo}
2. It doesn't like .if ${loop_item} ==
Update TSO limits to include all headers.
To make driver programming easier the TSO limits are changed to
reflect the values used in the BUSDMA tag a network adapter driver is
using. The TCP/IP network stack will subtract space for all linklevel
and protocol level headers and ensure that the full mbuf chain passed
to the network adapter fits within the given limits. See r287775
for a more detailed description.

Make the system queue header file fully usable within C++ programs by
adding macros to define class lists.
This change is backwards compatible for all use within C and C++
programs. Only C++ programs will have added support to use the queue
macros within classes. Previously the queue macros could only be used
within structures.
The queue.3 manual page has been updated to describe the new
functionality and some alphabetic sorting has been done while
at it.

Always clear TDB_USERWR before fetching system call arguments. The
TDB_USERWR flag may still be set after a debugger detaches from a
process via PT_DETACH. Previously the flag would never be cleared
forcing a double fetch of the system call arguments for each system
call. Note that the flag cannot be cleared at PT_DETACH time in case
one of the threads in the process is currently stopped in
syscallenter() and the debugger has modified the arguments for that
pending system call before detaching.
When a process group leader exits, all of the processes in the group are
sent SIGHUP and SIGCONT if any of the processes are stopped. Currently this
behavior is triggered for any type of process stop including ptrace() stops
and transient stops for single threading during exit() and execve().
Thus, if a debugger is attached to a process in a group when the leader
exits, the entire group can be HUPed. Instead, only send the signals if a
process in the group is stopped due to SIGSTOP.
Threads holding a read lock of a sleepable rm lock are not permitted
to sleep. The rmlock implementation enforces this by disabling
sleeping when a read lock is acquired. To simplify the implementation,
sleeping is disabled for most of the duration of rm_rlock. However,
it doesn't need to be disabled until the lock is acquired. If a
sleepable rm lock is contested, then rm_rlock may need to acquire the
backing sx lock. This tripped the overly-broad assertion. Fix by
relaxing the assertion around the call to sx_xlock().
