john: Update to 1.9.0

pkgsrc changes:
 - Document all the patches
 - Honors user's CFLAGS and don't remove -Wall from CFLAGS in patch-aa: they are
   usually pretty useful
 - Unset OPT_{NORMAL,INLINE} optimizations via MAKE_FLAGS to minimize patch-aa
 - Remove not needed NO_CONFIGURE
 - Use pre-configure as stage for SUBST (now that NO_CONFIGURE is removed)

Changes:
The following changes have been made between John 1.8.0 and 1.9.0:

* Increased the interleaving for bcrypt on x86-64 from 2x to 3x for a major
speedup on CPUs without SMT.  Unfortunately, this sometimes results in a minor
performance regression when running multiple threads on CPUs with SMT.
* Recognize the $2b$ bcrypt prefix.
* In the generic crypt(3) format, detect descrypt with valid vs. invalid salts
as separate id's for our heuristics on supported hash types.
* Introduced a number of optimizations for faster handling of large password
hash files, including loading, cracking, and "--show".  Some of these \ 
use more
memory than before, yet in a more efficient manner.
* Benchmark using all-different candidate passwords of length 7 by default.
* Dropped undocumented special handling of "Mc" in 'c' and 'C' rule \ 
commands.
* Dropped undocumented limitation of the 'M' and 'Q' rule commands where they
would sometimes memorize/check only up to the current hash type's length limit
yet this optimization wouldn't necessarily be transparent (e.g., if a later
command would extract a substring from above the hash type's length limit and
bring it to within the limit).
* Implemented special-case handling of repeated rule commands '$', '^', '[',
']', '{', and '}', as well as faster handling of the 'D' command.
* When built with "--fork" support, disallow session names with all-digit
suffixes since these clash with those produced by "--fork".
* Forward SIGTERM to --fork'ed children.
* Set stdout to line buffered (rather than potentially fully buffered), except
for "--stdout", "--show", and auxiliary programs such as \ 
"unshadow".
* On Windows, restore normal processing of Ctrl-C in case our parent (such as
Johnny the GUI) had disabled it.
* Added linux-x86*-avx512 and linux-x86*-avx2 make targets, which use
respectively AVX-512 and AVX2 for bitslice DES.
* Added linux-mic make target for Intel MIC (first generation Xeon Phi, aka
Knights Corner), which uses its 512-bit SIMD intrinsics for bitslice DES.
(For second generation Xeon Phi, aka Knights Landing, use linux-x86-64-avx512.)
* Added linux-arm64le, linux-arm32le-neon, and linux-arm32le make targets.
(The first two of these make use of ASIMD or NEON for bitslice DES.)
* Added linux-sparc64 make target.
* Made a minor optimization to MMX and SSE2 assembly code for LM hash.
* Dropped Ultrix and SCO support.
* Don't probe for alternate config file names (like john.ini when on Unix).
* "DokuWiki" external mode sample has been added to the default john.conf.
* Fixed operator precedence in the external mode compiler to be the same as C.
* Fixed an out of bounds write bug in the external mode virtual machine.
* Fixed a bug introduced in version 1.7.4 in the wordlist rules engine, where
some sequences of rule commands could overflow a word buffer.
* Fixed a bug where unaligned access SSE/AVX instructions would unnecessarily
be generated by GCC 4.6+ in the bitslice DES code in non-OpenMP builds.
* Fixed a bug where "Warning: no OpenMP support for this hash type" \ 
could be
printed in "--stdout" mode.
* Made assorted other bugfixes, portability and documentation enhancements.
