at boot.
Add a ksyms_mod_foreach() function to iterate a callback function over the
set of elf symbols for a specific module (netbsd included).
Add kern_ctf.c and mod_ctf_get() to allow the retrieval and decompression
of CTF sections for a specific module.

Replace more printfs with aprint_normal / aprint_verbose
Makes "boot -z" go mostly silent for me.

Remove highly questionable assert which demans that the kernel symbol
table is in memory at a lower address than the string table.

Initialize SYMTAB_SPACE ksyms during ksyms_init. Per PR port-evbarm/40311.

Make the fake ELF object work with gdb.

- Output a .bss section and make all the symbols relative to it, instead
of making them absolute.
- Output a single load section, no need for two.

Make the fake ELF object work with gdb.

- Output a .bss section and make all the symbols relative to it, instead
of making them absolute.
- Output a single load section, no need for two.

'gdb /dev/ksyms' still doesn't work because ksyms doesn't do mmap yet.

As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

Our qsort() is inappropriate for kernel use because it makes recursive
calls. Replace it with a kheapsort() function in kernel. Pointed out
by tron@.

Remove unneeded includes.

Fix ksyms_getname() broken in previous.

- Local symbols could shadow globals in some instances. Fix it.

- mutex_enter() from ksyms_getval() could panic due to a change made
in revision 1.40. Fix it.

- Local symbols could shadow globals in some instances. Fix it.

- mutex_enter() from ksyms_getval() could panic due to a change made
in revision 1.40. Fix it.

- Replace the p-tree with a binary search of global symbols. Saves about
250kB of wired memory on i386 and allows for faster lookups within
module symbol tables.
