and getipnodeby*() thread-safe.
Our res_*() is not thread-safe. So, we share lock between
getaddrinfo() and getipnodeby*(). Still, we cannot use
getaddrinfo() and getipnodeby*() in conjunction with other
functions which call res_*().

the FPU state on receiving and returning from a signal.
The FPU save and restore macros are no longer needed, but
remain defined in case we need to use them again (something
else breaks). They'll be removed permanently once new
syscalls are added to handle the new i386 ucontext size.
some deliberation the name "libbsdxml" was chosen since it conveys the two
most important attributes: "Private to FreeBSD" and "XML".
Add a skeleton man-page to give the credit and point for further
documentation. (If somebody wants to write a true mdoc manpage for
this I am sure both the eXpat people and I will be grateful).

and `sigwaitinfo'. This complies with IEEE Std 1003.1-2001.
ceased to be useful when the number of "special processes" went from 3
to one per device. I considered replacing it with a "kernel threads"
section, but this seemed like the wrong place for that.

one into the latter and removed the former.
This works around the bug that some broken Makefiles add -I.../src/include
to CFLAGS, resulting in the old math.h being preferred and differences
between the headers possibly being fatal.
The merge mainly involves declaring some functions as __pure2 although
they are not yet all strictly free of side effects.

Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.
These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.
This commit adds a number of such #includes.
Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

userland. If someone wants to implement a backup p_siglist in the kernel
for compatability and to export one could. For now, just tell KVM to hand
an empty signal set off to the userland.

This will be removed when a proper fix is made in the kernel
to save/restore the FP state without breaking the ABI.
-fomit-frame-pointer is not used). This is mostly moot for -current
because gcc-3 does the alignment (slightly incorrectly) in main().
This patch is intended for easy MFC'ing and should be backed out in
-current soon since it causes compiler warnings and better fixes are
possible in -current. The best fix is to do nothing here and wait for
gcc to do stack alignment right. gcc-3 aligns the stack in main(), but
does it too late for main()'s local variables and too late for anything
called before main(). A misaligned stack is now more than an efficiency
problem, since some SSE instructions in some or all (hardware)
implementations trap on misaligned operands even if alignment checking
is not enabled.
