move multiple copies of code for parsing boot.cfg file from sparc, i386
and zaurus into libsa/bootcfg.{h,c}. largely retained i386 parsing logic
in addition to keeping sparc dispatch function while remaining consistent
with boot.cfg(5).
previous sparc64 file format has been obsoleted but only used by boot
CDs distrib/sparc64/bootfs/boot.cfg has been updated to compensate.
exported names have been prefixed with either BOOTCFG_ or bootcfg_ as per
feedback from christos@
tested on amd64 & sparc64 but not zaurus.
their content into "itp". There's no need for re-reading the whole binary and
trying to find this section again. Just use "itp".
DEBUG_FREEBSD_ELF is now unused, so remove its references in amd64/conf/ALL
and i386/conf/ALL.
- Add 4G freelist to i386 -- there may be higher addresses if PAE.
- Add 64G and 1T freelists to amd64.
- Simplify freelist setup code and condense it into a table.
- Add x86_select_freelist to get a freelist guaranteed to yield
addresses no greater than a prescribed maximum address.
x86_select_freelist takes a uint64_t, not a paddr_t or bus_addr_t, so
that you can pass in, e.g., a 36-bit maximum address without needing
to write conditionals for i386/PAE.
No objections on port-x86:

One of these (probably the first) is needed to stop the eh-frame
section being created.
The eh_frame section is loadable and bloats the boot images.
This might be enough to make pxeboot work.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
Add support for the forthcoming AVX-512 registers.
Code compiled with -mavx seems to work, but I've not tested context
switches with live ymm registers.
There is a small cost on fork/exec (a larger area is copied/zerod),
but I don't think the ymm registers are read/written unless they
have been used.
The code use XSAVE on all cpus, I'm not brave enough to enable XSAVEOPT.
x87 control word.
This means that nothing outside fpu.c cares about the internals of the
fpu save area.
New kernel modules won't load with the old kernel - but that won't matter.
The result is only written to sysctl nodes at the moment.
I see:
machdep.fpu_save = 3 (implies xsaveopt)
machdep.xsave_size = 832
machdep.xsave_features = 7
Completely common up the i386 and amd64 machdep sysctl creation.
kernel stack to the top.
Change the pcb layouts so that fpu save area is at the end and is
64byte aligned ready for xsave (saving the ymm registers).
