That also allows ports to be able to use a modern version of readline

The number of vm fictitious regions was limited to 8 by default, but
Xen will make heavy usage of those kind of regions in order to map
memory from foreign domains, so instead of increasing the default
number, change the implementation to use a red-black tree to track vm
fictitious ranges.
The public interface remains the same.

vm/vm_phys.c:
- Replace the vm fictitious static array with a red-black tree.
- Use a rwlock instead of a mutex, since now we also need to take the
lock in vm_phys_fictitious_to_vm_page, and it can be shared.
With the move of atf-sh into /usr/libexec in r267181, some of the
tests in the integration_test program broke because they could not
execute atf-sh from the path any longer.
This slipped through because I do have a local atf installation in
my home directory that appears in my path, hence the tests could
still execute my own version.
Fix this by forcing /usr/libexec to appear at the beginning of the
path when attempting to execute atf-sh.
To make upgrading easy (and to avoid an unnecessary entry in UPDATING),
make integration_test depend on the Makefile so that a rebuild of the
shell script is triggered. This requires a hack in the *.test.mk files
to ensure the Makefile is not treated as a source to the generated
program. Ugly, I know, but I don't have a better way of doing this at
the moment. Will think of one once I address the TODO in the *.test.mk
files that suggests generalizing the file generation functionality.

Although it is probably unwise to use this, POSIX is clear that leading
zeroes are permitted in positional parameters (and do not indicate octal).
Such positional parameters are checked for being unset and/or null
correctly, but their value is incorrectly expanded.
The test locale1.0 depends on locale support; it is meaningless without a
working LC_MESSAGES.
I added an OptionalObsoleteFiles.inc entry.

While it is possible to create and write file, modify its permissions, etc.
without ever doing sync, it looks odd that it is required for setting
extended file attributes on ZFS. UFS does not do sync there too.
Samba uses those extended attributes to store some its data, and doing it
synchronously by many times reduces file creation performance for systems
without SLOG device.

That should make operation more kind to multi-initiator environment.
Without this, other initiators may find out that something bad happened
to their commands only via command timeout.
Testing shown that both original queued design with separate task queue,
and recent direct execution design had significant flaw: If abort request
arrives just after the victim, the last one may not be in the ooa_queue
yet, and so invisible for the task management function.
Unlike original queued implementation, use same queue for all SCSI and
TASK requests from the same initiator. That avoids races between them:
task functions are always executed in proper time, relatively to other
requests.
tools/regression/file/flock/flock.c, which completes the fix in
r192685. When the lock was stolen from us, retry the whole lock
sequence in kernel, instead of returning EINTR to usermode and hoping
that application would handle it correctly by restarting the lock
acquire.

fflag to ignore fts_read errors, but stop deleting from that directory
because no further progress can be made.
When building a kernel with a high -j value on a high core count
machine, during the cleanobj phase we can wind up doing multiple rm
-rf at the same time for modules that have subdirectories. This
exposed this race (sometimes) as fts_read can return an error if the
directory is removed by another rm -rf. Since the intent of the -f
flag was to ignore errors, even if this was a bug in fts_read, we
should ignore the error like we've been instructed to do.
