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.

-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.

Use the correct constants directly from sysconf() rather than calling

hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI. FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about. As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use. All callers in the
tree are updated to use the correct prototype.
Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.
