Merge branch 'master+patches' into bleeding-jumbo. NOTE: The charset files are
gone for now. The old ones are incompatible. For testing, create new ones from
the Rockyou list, or something.

* master+patches:
  Source code indentation: consistently put the blocks after "if" on a new line
  Dropped the remnants of old .chr file compatibility code
  Revised incremental mode such that the counts of character indices grow independently for each position.  This change breaks compatibility with older .chr files.
  Fixed OpenMP-specific issues with the previous change: make stderr available in the parallel region, wrap the warning printing in "#pragma omp critical".
  1.7.9.8: - The formats interface has been enhanced to better support GPU implementations (in jumbo), as well as fast hashes on multi-CPU systems (not yet made use of). - Handle possible NULL returns from crypt() and crypt_r().
  Handle possible NULL returns from crypt() and crypt_r()
  Revised the crypt_all() format method prototype and semantics, as well as the semantics of get_key() and some other format methods called after crypt_all(), such that crypt_all() may alter and/or generate candidate passwords on its own, including beyond its originally supplied candidate password count.
  Revised the crypt_all() format method prototype and semantics such that it may optionally perform preliminary checking for possible matches.
  Added reset(), a format method called whenever the set of password hashes being cracked changes, such as after self-test, but before actual cracking starts. Normally, this is a no-op since a format implementation shouldn't mess with the database unnecessarily.  However, when there is a good reason to do so this may e.g. transfer the salts and hashes onto a GPU card.
  Added support for format destructors (the done() method), which is important e.g. when running --test across many GPU-using formats, not to run out of GPU memory after testing only a subset of the formats.
  Self-test each format just once (rather than before the start of each cracking mode) unless we're debugging.
  1.7.9.7: Fixed a bug introduced in 1.7.9.5 where --show would omit the first hex digit of LM hashes.  Thanks to magnum for reporting this and providing the patch. (The actual fix to loader.c was committed separately, on 2012/08/23.)
