headers properly (right justified for numbers, left justified for
everything else).
This fixes the alignment of the fields on i386, sparc64 and amd64
today but does not dynamically assign column widths or bear in mind
that some of the values may be 64-bit in the future.

Allow the user to run unifdef without defining any symbols. This is
useful in conjunction with the -k flag.
Fix a bug in the -s handling code that would have caused out-of-bounds
array accesses.
Add a -n option to insert #line directives in the output.
Ignore comment markers inside string and character literals

More accurate copyright notices.
Add support for passing in a mutex. If NULL is passed a global
subr_unit mutex is used.
Add alloc_unrl() which expects the mutex to be held.
Allocating a unit will never sleep as it does not need to allocate
memory.
Cut possible range in half so we can use -1 to mean "out of number".
Collapse first and last runs into the head by means of counters.
This saves memory in the common case(s).
ever working correctly: the code was linking the QHs together but
then immediately overwriting the "next" pointers. Oops. Also
initialise qh_endphub, since the EHCI spec says that we should
always set the pipe multiplier field to something sensible.
This appears to make basic split transactions work, so enable split
transactions for control, bulk and interrupt pipes (split isochronous
transfers are not yet implemented). It should now be possible to
use USB1 devices even when they are connected through a USB2 hub.
particularly good reason to do this, except that __strong_reference
does type checking, whereas __weak_reference does not.
On Alpha, the compiler won't accept a 'long double' parameter in
place of a 'double' parameter even thought the two types are
identical.

- Don't waste time calling bus_dmamap_load_mbuf() if we know the mbuf
chain is too long to fit in a TX descriptor, call m_defrag() first.
- Convert fxp(4) to use bus_dmamap_load_mbuf_sg().
initializing the sysctl mibs data before actually using them.
The original patchset (which is the actual version that is running
on my testboxes) have checked whether all of these sysctls and
refuses to do background fsck if we don't have them. Kirk has
pointed out that refusing running fsck on old kernels is pointless,
as old kernels will recompute the summary at mount time, so I
have removed these checks.
Unfortunatelly, as the checks will initialize the mib values of
those sysctl's, and which are vital for the runtime summary
adjustment to work, we can not simply remove the check, which
will lead to problem when running background fsck over a dirty
volume. Add these checks in a different way: give a warning rather
than refusing to work, and complain if the functionality is not
available when adjustments are necessary.

for the duration of the send() call. Such approach may be less than ideal
in threading environment, when several threads share the same socket and it
might happen that several of them are calling linux_send() at the same time
with and without SO_NOSIGPIPE set.
However, such race condition is very unlikely in practice, therefore this
change provides practical improvement compared to the previous behaviour.

- If a long double has 113 bits of precision, implement fma in terms
of simple long double arithmetic instead of complicated double arithmetic.
- If a long double is the same as a double, alias fma as fmal.
