Prep .c files for removing the #includes from */archdep.h
* replace #include "archdep.h" with #includes of what is used, pulling in
"syscall.h", "util.h", and "archdep.h" as needed
* delete #include <sys/syscall.h> from syscall.h
* only pull in <sys/stat.h> to the three files that use _dl_fstat(),
forward declare struct stat in syscall.h for the others
* NBBY is for <sys/select.h> macros; just use '8' in dl_printf.c
* <machine/vmparam.h> is only needed on i386; conditionalize it
* stop using __LDPGSZ: use _MAX_PAGE_SHIFT (already used by malloc.c)
where necessary
* delete other bogus #includes, order legit per style: <sys/*> then
<*/*>, then <*>, then "*"

make three mib[] arrays const, as was done in libc

Add missing space in stack smash handler error message.
ok kettenis@, deraadt@

On retguard systems, remove the ld.so-local stack-protector handling
functions because retguard uses hard-traps instead.
ok mortimer.

Use a static chacha instance to fill randomdata sections. Avoids looping
over a syscall for randomdata sections larger than 256B.

ok djm@ deraadt@ kettenis@

On fatal errors, kill ourselves with thrkill(0,9,NULL) instead of
simply exiting, via helper functions _dl_die(), _dl_diedie(), and
_dl_oom().

prompted by a complaint from jsing@
ok jsing@ deraadt@

the slimmed down random functions inside ld.so are strict clones of the
libc arc4random API, so call them _dl_{arc4random,arcrandombuf}
ok tedu guenther

use a larger chunk for getentropy() and save some for next time.
coalesces some syscalls instead of one per random number.
ok deraadt

Rename the system call sendsyslog2 to sendsyslog. Keep the old one
as osendsyslog for a while. The three argument variant is the only
one that will stay.
input kettenis@; OK deraadt@

Switch ld.so's stack smash handler from sendsyslog to sendsyslog2
and pass the LOG_CONS flag like libc's handler.

ok deraadt@ bluhm@ (who had a similar diff)

Export environ and __progname, making the latter a copy of just the filename
portion like crt0 does. This is prep for eliminating _dl_fixup_user_env()
Mark almost everything in resolve.h as hidden,

Mark almost everything in resolve.h as hidden, to improve code generation.

If _dl_progname exceeds half the syslog buffer, truncate it with "...",
so that the remaining information is more visible

<sys/param.h> to <limits.h> conversion. Verified binaries
ok millert, thanks to doug for process advice

avoid void arithmetic. from david carlier

Now that we have sendsyslog(2), we can directly use it in the
(previously completely retarded) stack_smash_handler of ld.so
ok beck miod tedu

rm unneeded includes; prompted (partly) by kettenis@

move from sysclt(KERN_ARND) to getentropy(2); ok miod@, kettenis@

Move to a non-zeroing _dl_malloc, a _dl_calloc and _dl_reallocarry and
fix _dl_strdup to return NULL instead of crash; ok deraadt@

Make _dl_randombuf invoke sysctl KERN_ARND in 256-byte chunks, for this is
(currently) the largest output you can get from it.

ok deraadt@

Move to (slightly stripped) version of libc malloc; ok deraadt@
