the whole RLIMIT_STACK-sized region of the kernel-allocated stack as
the stack of main thread.
By default, the main thread stack is clamped at 2MB (4MB on 64bit
ABIs) and the rest is used for other threads stack allocation. Since
there is no programmatic way to adjust the size of the main thread
stack, pthread_attr_setstacksize() is too late, the knob allows user
to manage the main stack size both for single-threaded and
multi-threaded processes with the rlimit.

page queue even when the allocation is not wired. It is
responsibility of the vm_page_grab() caller to ensure that the page
does not end on the vm_object queue but not on the pagedaemon queue,
which would effectively create unpageable unwired page.
In exec_map_first_page() and vm_imgact_hold_page(), activate the page
immediately after unbusying it, to avoid leak.
In the uiomove_object_page(), deactivate page before the object is
unlocked. There is no leak, since the page is deactivated after
uiomove_fromphys() finished. But allowing non-queued non-wired page
in the unlocked object queue makes it impossible to assert that leak
does not happen in other places.

Remove the .t wrappers
Rename all of the TAP test applications from test-<test> to
<test>_test to match the convention described in the TestSuite
wiki page
humanize_number_test.c:
- Fix -Wformat warnings with counter variables
- Fix minor style(9) issues:
-- Header sorting
-- Variable declaration alignment/sorting in main(..)
-- Fit the lines in <80 columns
- Fix an off by one index error in the testcase output [*]
- Remove unnecessary `extern char * optarg;` (this is already provided by
unistd.h)

The new code uses a "test discovery mechanism" to determine

the build starts.
This adds a new variable DHDRS that contains a list of all DTrace
header files. Then, we use the beforedepend hook to make sure the
heaeder files are built.
Introduce a beforebuild dependency (from projects/bmake) based on
feedback from Simon J. Gerraty. This lets us generate the header
files without running make depend.

- Install the Kyuafile by adding FILES to FILESGROUPS
- Run the testcases with an unprivileged user
Some of the testcases depend upon behavior that's broken when
run as root on FreeBSD because of how permissions are treated
with access(2) vs eaccess(2), open(2), etc
- Simplify the test driver to just inspect the exit code from
run_test because it now exits with 0 if successful and exits
with !0 if unsuccessful
- Don't do ad hoc temporary directory creation/deletion; let Kyua
handle that

Most of the tablearg-supported opcodes does not accept 0 as valid value:
O_TAG, O_TAGGED, O_PIPE, O_QUEUE, O_DIVERT, O_TEE, O_SKIPTO, O_CALLRET,
O_NETGRAPH, O_NGTEE, O_NAT treats 0 as invalid input.
The rest are O_SETDSCP and O_SETFIB.
'Fix' them by adding high-order bit (0x8000) set for non-tablearg values.
Do translation in kernel for old clients (import_rule0 / export_rule0),
teach current ipfw(8) binary to add/remove given bit.
This change does not affect handling SETDSCP values, but limit
O_SETFIB values to 32767 instead of 65k. Since currently we have either
old (16) or new (2^32) max fibs, this should not be a big deal:
we're definitely OK for former and have to add another opcode to deal
with latter, regardless of tablearg value.
Many compilers may optimize away the overflow check `msg + l < msg',
where `msg' is a pointer and `l' is an integer, because pointer
overflow is undefined behavior in C.
Use a safe precondition test `l >= eom - msg' instead.

trees. This happens because the logic inserting items into the radix
tree is allocating empty radix levels, when index zero does not
contain any items.
- Add proper error case handling, so that the radix tree does not end
up in a bad state, if memory cannot be allocated during insertion of
an item.
- Add check for inserting NULL items into the radix tree.
- Add check for radix tree getting too big.

r269533, which was tested before r269457 was committed, implicitely
relied on the Giant to protect the manipulations of the softdepmounts
list. Use softdep global lock consistently to guarantee the list
structure now.
Insert the new struct mount_softdeps into the softdepmounts only after
it is sufficiently initialized, to prevent softdep_speedup() from
accessing bare memory. Similarly, remove struct mount_softdeps for
the unmounted filesystem from the tailq before destroying structure
rwlock.
