other systems to fit into the same mold, so add copyright

nor are they the same size.

(sorry, my other changes were accidentally premature)

remember to set EACCES in bcrypt_checkpass for hash differences.
the higher level crypt_checkpass function will reset errno to EACCES in
all cases, which is probably the right behavior, but this change gives code
working with the lower level functions the correct errno if they care.

what's going on.

guenther suggested using thread time, which actually may improve accuracy
if somebody puts this in a threaded program.

from this case where we have a static buffer and cant realloc.

use global data. The simplest fix is to only check blowfish passwords,
and implicitly lock out DES passwords.
crypt_checkpass is currently only used in one place, passwd, to verify
the local user's password, so this is probably acceptable.
Gives people a little more time to migrate away from DES before introduing
checkpass into more places.

ramdisk libc builds.  there has to be a better way without #ifdef's
in gross places, but I don't see it yet.

naddy found sparc64 gets a little slower when unrolled.
ok deraadt

update SYNOPSIS and DESCRIPTION and add STANDARDS

rewrite the function to be simpler as well. the compiler can unroll the
loop for us if necessary.

It may take a few iterations to get the tone right.

the same thingies.  Therefore these "lists of functions" man pages can go
away.
Hurray!  I've wanted these pages to die for around 10 years!

to returning strong random by default, source from arc4random(3).
Parameters to the seeding functions are ignored, and the subsystems remain
in strong random mode.  If you wish the standardized deterministic mode,
call srand_deterministic(), srandom_determistic(), srand48_deterministic(),
seed48_deterministic() or lcong48_deterministic() instead.
The re-entrant functions rand_r(), erand48(), nrand48(), jrand48() are
unaffected by this change and remain in deterministic mode (for now).
Verified as a good roadmap forward by auditing 8800 pieces of software.
Roughly 60 pieces of software will need adaptation to request the
deterministic mode.
Violates POSIX and C89, which violate best practice in this century.

Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting
1UL 32-bits to the left causes an overflow. This replaces the constant 1UL with
(size_t)1 so that we get the correct constant size for the platform.

Several functions that need to be redefined for a Windows port are right
in the middle of other code that is relatively portable. This patch
isolates the functions that need Windows-specific implementations so
they can be built conditionally in the portable tree.

The former is not used anywhere in NetBSD, FreeBSD, or DragonFly
and not supported by groff, so i'm going to delete it from mandoc(1).
We don't need two macros for the same thing.
