Removed unused includes.
Removed used includes of <sys/queue.h> and <sys/time.h>, since these are
standard pollution (especially the latter).

Garbage-collected kvm_readswap(). This was once used by kvm_uread(), but
kvm_uread() now just reads /proc/<pid>/mem and procfs hopefully handles
swapped out pages.
next step is to allow > 1 to be allocated per process. This would give
multi-processor threads. (when the rest of the infrastructure is
in place)
While doing this I noticed libkvm and sys/kern/kern_proc.c:fill_kinfo_proc
are diverging more than they should.. corrective action needed soon.
X_db_search_symbol(). Otherwise we don't see important symbols in
non-verbosely written assembler code.
NetBSD already has this. The kld version already has a stronger form
of it without really trying -- linker_ddb_search_symbol() doesn't
support ddb's symbol search strategy parameter, so the kld
X_db_search_symbol() doesn't pass the parameter to linker_ddb...() and
linker_ddb...() doesn't make distinctions based on the symbol type.
db_elf.c now works better than db_kld.c when it works (which is essentially
when there are no modules except the kernel). It works after booting
with -d. db_kld.c doesn't work until lots of SYSINIT()s have run.
symbol table sections. Reconstruct the necessary section headers from
(ksym_start, ksym_end). This was much easier than converting to use
module metadata, and just works for static symbols, unlike db_kld when
there is no module metadata. Initialize (ksym_start, ksym_end) from
bootinfo on i386's only.
The boot loader should load section headers for all sections that it
loads, and apparently did this for at least the symbol table sections
when this file last worked under FreeBSD (on alphas only) and always
did this under NetBSD (where this file was obtained from). At least
on i386's, boot2 discards the section headers (except for converting
them to (bootinfo.bi_symtab, bootinfo.bi_esymtab), and as far as I can
tell, loader(8) discards them apart from converting them to the bootinfo
values and module metadata.
and renaming ALIGNED_POINTER() to _ALIGNED_POINTER() plus the following
hacks for i386's:
- define _ALIGNED_POINTER() if it is not already defined. Most non-i386
arches define it <machine/param.h> define it in <machine/param.h>,
although none actually used it in the kernel.
- define ksym_start and ksym_end. Most non-i386 arches still define and
initialize these in machdep.c although they didn't used them. Here is
a better place to define them but not to initialize them.
KAME did the modification only to _dns_getaddrinfo(). However,
it is not sufficient, and res_queryN() should be modified, too.
So, I did same modification to res_queryN().

to control the mapping of things like the ACPI and APM into memory.
The problem is that starting X changes these values, so if something
was using the bits of BIOS mapped into memory (say ACPI or APM),
then next time they access this memory the machine would hang.
This patch refuse to change MTRR values it doesn't understand,
unless a new "force" option is given. This means X doesn't change
them by accident but someone can override that if they really want
to.

Don't set __LONG_LONG_SUPPORTED for gcc-1. I didn't check exactly
when gcc started to support long long, but it was in the version
of gcc in FreeBSD-1.0 (gcc-2.4.5).
Other C99 features should be ifdefed similarly, but the ifdefs for
old versions of gcc will be more complicated since the features
weren't in all versions of gcc-2.
