Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

While here, undo our libfdt hack of not including <stdlib.h> if we're
compiling _STANDALONE.

r324844: When building standalone, don't define errno. Let the definition from
stand.h override. This is similar to what we do in the kernel.

r326089: loader.efi: efipart does not recognize partitionless disks

r326090: net_parse_rootpath() has no parameters

r326143: Fix theoretical integer overflow issues. If the product here is

r326448: Fix all warnings related to geli and ZFS support on x86.

r326484: Const poison the propname.

r326485: Delcare md_load in libofw.h. Make all prototypes match for ofw

r326486: Include machine/md_var to pick up __syncicache prototype.

r326487: Cast mdp (a vm_offset_t) to void * to match prototype.

r326488: e_entry can be smaller than a pointer. Cast it to an intptr_t

r326490: Declare our strange brand of main().

r326491: Disconnet ps3 from the build. There's too many warnings to fix.

r326492: Cast void * pointer to char * so the arg matches the %s format.

r326493: Provide a md_load64 prototype.

r326494: Mark two things as unused (since they are only sometimes used)

r326495: Now it's safe to bump WARNS to 1.

r326504: Switch to proper MK_LOADER_GELI tests.

r326507: increase maximum size of zfsboot

r326584: When building standalone, include stand.h rather than the kernel

r326585: Include ficl.h before anything else

r326586: No need to include the userland md5.h, the kernel one is just fine.

r326587: Use the kernel relative paths, rather than the userland relative
paths

r326588: Need to include skein in the include path

r326589: Make sure we include the right path for skein.h

r326590: Prefer stdint.h to inttypes.h

r326591: This isn't NetBSD specific code. Include these for any kernel /

r326592: Don't inherit CFLAGS. This a specialized test program.

r326593: Stop building with the standard system headers.

r326594: Now that we offer a semi-sane standards-ish set of #include files,
stop hacking includes with sed.

r326600: Since this is contrib code, create an upstreamable version of my

r326616: dhcp_try_rfc1048() is not used any more

r326671: Avoid setting -Wno-tentative-definition-incomplete-type with gcc.

r326707: Add partial support signal.h functioanlity. Pull in
machine/signal.h

built standalone.

r326709: Provide implementations for iscntrl, ispunct and isgraph.

hings up.

r326711: Const poison a couple of interfaces.

r326712: Create interp class.

r326714: boot1.c needs EFI_ZFS_BOOT too, so add it globally.

users

r326856: Fix comments after bump in size.

r326858: Revert r326855: Cargo cut a fix for the regressions r326585 caused.

r326886: Panic in sbrk if setheap hasn't been called yet. This is preferable
o a mysterious crash

r326887: Remove the 'mini libstand in libstand' that util.[ch] provided.

r326914: Move loader-only defines to loader.mk from defs.mk

r326926: Move loader help file definitions to being 100% inside of
loader.mk.

r326927: libficl is only ever used in a loader (never a boot) program. Move
it.

r326960: Simplify things a little. The RETURN macro isn't required.

r326961: Interact is always called with NULL. Simplify code a little

r326962: Hoist btx include stuff to i386/Makefile.inc

r326963: No need to use relative paths like this here.

r327351: Fix ubldr. uboot/lib uses defines for the loader.

r327453: Add a validbcd() routine that uses the bcd2bin_data[] array

r327390: Garbage-collect loader.ps3. It is currently disconnected from the
build and kboot replaces.

r328437: Split panic routine

r328441: abort() should be marked __dead2 since it won't return.

r328448: Make exit() never return until host_exit can be written.

r328449: Tag unreachable places as such. I left the while (1); in place

r328612: Move strtold wrapper from strtol.c to its own strtold.c.

r328613: Kill copies of strtol and strtoul.

r328615: Update stand.h for changes for strto*l

Renumber clauses to reduce diffs to other versions

NetBSD, OpenBSD, and Android's Bionic number the clauses 1 through 3,
so follow suit to make comparison easier.

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a
load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.

Please test any code you have that uses the C standard locale functions!

Whitespace/style tweaking of prev. commit.

POSIX says that 0[xX] prefix is _optional_ even in base 16 case, make it
really so.

"If the value of base is 16, the characters 0x or 0X may optionally
precede the sequence of letters and digits, following the sign if
present."

Found by: joerg

Style: One space between "restrict" qualifier and "*".

- Add the 'restrict' qualifier to the function prototypes and
definitions of the functions that convert strings to numbers
and are defined by IEEE Std 1003-1.2001.
- Use ANSI-C function definitions for all of the functions
mentioned above plus strtouq and strtoq.
- Update the prototypes in the manual pages.

Fix the style of the SCM ID's.
I believe have made all of libc .c's as consistent as possible.

Return 'c' back to signed due to potential comparison problems

Make it works for non ASCII compatible encodings too.
The only assumption left is that 'A'..'Z' 'a'..'z' both are contiguous

Back out national digits support, POSIX explicetely disallows it:

The definition of character class digit requires that only ten characters
-the ones defining digits- can be specified; alternate digits (for
example, Hindi or Kanji) cannot be specified here. However, the encoding
may vary if an implementation supports more than one encoding.

The definition of character class xdigit requires that the characters
included in character class digit are included here also and allows for
different symbols for the hexadecimal digits 10 through 15.

Don't ever assume that isdigit() is always subset of isxdigit()

Base 36 is allowed.

Put back base > 35 check. If someone dislike it, plese discuss it with
standards group first.

Understand national (non-ASCII) digits now
Allow bases >=36 again
Misc cleanup

Portability fix: use unsigned cast to guaranteed positive part of expression
in case {L}LONG_MAX > abs({L}LONG_MIN). Non-functional change - we don't
have any such platforms.

Remove rcsids and unneded include

'acc' is not initialized in one hypotetical case, fix it

Locale *is* used in strto*l*(), at least for isspace(), so remove
'locale not used' statement from comments and BUGS section of manpage.

strtol(): fix non-portable 'cutoff' calculation using the same method as
in strtoll().

Cleanup 'cutoff' calculation, remove unneded casts. Misc. cleanup to
make all functions looks the same.

Implement EINVAL reaction per POSIX, document it in manpage, corresponding
POSIX example quotes here:

------------------------------------------------
If the subject sequence is empty or does not have the expected form, no
conversion is performed; the value of str is stored in the object pointed
to by endptr, provided that endptr is not a null pointer.

If no conversion could be performed, 0 shall be returned and errno may be
set to [EINVAL].

[EINVAL] The value of base is not supported.

Since 0, {LONG_MIN} or {LLONG_MIN}, and {LONG_MAX} or {LLONG_MAX} are
returned on error and are also valid returns on success, an application
wishing to check for error situations should set errno to 0, then call
strtol( ) or strtoll ( ), then check errno.

General -Wall warning cleanup, part I.

strtol and atoi VERY broken in 8bit chars locale, i.e. if you pass something
like 38400<any 8bit char, isalpha> it not detect this stuff and
produce very big number instead. Fixed by operating with unsigned char
and checking for isascii. (secure/telnetd hits by it f.e.)
