Modify logic for utilizing the data segment, such that it is possible to
create huge allocations there.
Shrink the data segment when deallocating a chunk, if it is at the end of

Rename chunk_size to csize in huge_malloc(), in order to avoid masking a

We can also negate individual conditions. The ruleset language is
a superset of the previous language, so old rules should continue
to work.
These changes require a change to the API between libugidfw and the
mac_bsdextended module. Add a version number, so we can tell if
we're running mismatched versions.
Update man pages to reflect changes, add extra test cases to
test_ugidfw.c and add a shell script that checks that the the
module seems to do what we expect.

far more convenient for libkvm to work with because of the page table
block at the beginning. As a result, the MD code is smaller.
libkvm will automatically detect old vs mini dumps on i386 and amd64.
libkvm will handle i386 PAE and non-PAE modes. There is a PAE flag in
the i386 minidump header to signal the width of the entries in the
page table block.
Other convenient values are also present, such as kernbase and the direct
map addresses on amd64.

as well as add __sparc_utrap_install to FBSD_1.0; these are required by
the SCD libc 64 psABI and thus meant to be officially exported symbols.
- Remove the __fpu_* entries as well as the __sigtramp entry altogether as
these are internal to the libc FPU emulation and the signal trampoline
initialization in sigaction(2) respectively and thus don't need to be
externally visible.
- Add __sparc_utrap_setup to the list of FBSDprivate symbols as it's used
in src/lib/csu/sparc64/crt1.c to initialize the libc FPU emulation (I
think alternatively src/lib/csu/sparc64/crt1.c could be changed to use
__sparc_utrap_install instead, at the expense of increasing the size of
executables a bit).
- Add an entry for the vfork symbol to the FBSD_1 list and entries for it's
associated symbols generated by the RSYSCALL() macro to the FBSDprivate
list. There's some magic in place that automatically generates code for
vfork() if there's no explicit MD code for it so it might make sense to
move these symbols from the MD symbol map files to a MI one.
The last two changes make the libc symbol versioning useable on sparc64.

Remove/avoid division where possible.
For the one division operation that remains in the critical path, add a
switch statement that has a case for each small size class, and do division
with a constant divisor in each case. This allows the compiler to generate
optimized code that does not use hardware division [1].
