While there, postpone initializing local curthread variable until
passed signal number is checked for validity.

This also fixes asserts on removal of the module for the mpc74xx.
The PowerPC 970 processors have two different types of events: direct events
and indirect events. Thus far only direct events are supported. I included
some documentation in the driver on how indirect events work, but support is
for the future.

Add an option WITHOUT_NCURSESW to suppress building and linking to
libncursesw. While wide character support it useful we'd like to
only need one ncurses library on embedded systems.

the virtio backends.
- Add a new ioctl to export the count of pins on the I/O APIC from vmm
to the hypervisor.
- Use pins on the I/O APIC >= 16 for PCI interrupts leaving 0-15 for
ISA interrupts.
- Populate the MP Table with I/O interrupt entries for any PCI INTx
interrupts.
- Create a _PRT table under the PCI root bridge in ACPI to route any
PCI INTx interrupts appropriately.
- Track which INTx interrupts are in use per-slot so that functions
that share a slot attempt to distribute their INTx interrupts across
the four available pins.
- Implicitly mask INTx interrupts if either MSI or MSI-X is enabled
and when the INTx DIS bit is set in a function's PCI command register.
Either assert or deassert the associated I/O APIC pin when the
state of one of those conditions changes.
- Add INTx support to the virtio backends.
- Always advertise the MSI capability in the virtio backends.

known in advance, or where the caller doesn't care and just keeps
reading until it hits EOF.
In fetch_read(): the socket is non-blocking, so read() will return 0
on EOF, and -1 (errno == EAGAIN) when the connection is still open but
there is no data waiting. In the first case, we should immediately
return 0. The EINTR case was also broken, although not in a way that
matters.
In fetch_writev(): use timersub() and timercmp() as in fetch_read().
In http_fillbuf(): set errno to a sensible value when an invalid chunk
header is encountered.
In http_readfn(): as in fetch_read(), a zero return from down the
stack indicates EOF, not an error. Furthermore, when io->error is
EINTR, clear it (but no errno) before returning so the caller can
retry after dealing with the interrupt.

simply not trying to return exactly what the caller asked for - just
return whatever we got and let the caller be the judge of whether it
was enough. If an error occurs or the connection times out after we
already received some data, return a short read, under the assumption
that the next call will fail or time out before we read anything.
As it turns out, none of the code that calls fetch_read() assumes an
all-or-nothing result anyway, except for a couple of lines where we
read the CR LF at the end of a hunk in HTTP hunked encoding, so the
changes outside of fetch_read() and http_readfn() are minimal.
While there, replace select(2) with poll(2).

properly include sys/ headers from the source tree instead of the
host.
These patches are also applied to libdwarf since libdwarf requires
the same sys/ headers as libelf.
device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line

The resolver in libc creates a kqueue for watching a single file descriptor.
This can be done using poll() which should be lighter on the kernel and
reduce possible problems with rlimits (file descriptors, kqueues).

one significant difference: for LIB32 builds both TARGET_ARCH
and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the
architecture of the host (e.g. amd64), while MACHINE_ARCH holds
the architecture were trying to build (e.g. i386). With both
set and different, r260022 changed the behaviour to interpret
the condition as building a cross-amd64 libkvm on i386, when
obviously we're trying to build an i386 version on amd64. When
COMPAT_32BIT is defined, we're building LIB32 and ignore the
value of TARGET_ARCH as we did before.
These files are required to get packages in ports to build against atf and
also to get a couple of currently-failing tests to pass.
I'm following the approach already used by the libusb pkg-config files
installed by the system regarding the location and the install rules.

As a result, the kernel needs to process shorter pathnames if fts is not
changing directories (if fts follows symlinks (-L option to utilities), fts
cannot open "." or FTS_NOCHDIR was specified).
Side effect: If pathnames exceed PATH_MAX, [ENAMETOOLONG] is not hit at the
stat stage but later (opendir or application fts_accpath) or not at all.
Because we respect the FreeBSD src tree layout under /usr/tests, and because
the layout of the tests in the atf distfile does not match the former, the
tests for atf-c++ were not able to find the process_helper binary.
Fix this by explicitly hardcoding the right path in the FreeBSD test suite.

Put test programs for internal modules into a 'detail' subdirectory of the
libatf-c and libatf-c++ test directories, just as the upstream distribution
does. This is necessary because the tests assume such layout to find the
process_helper program, and currently fail because of this divergence.
