by compiler/engine mismatches

Fredrik Lundh 770617b23e SRE fixes for 2.1 alpha:
-- added some more docstrings
-- fixed typo in scanner class (#125531)
-- the multiline flag (?m) should't affect the \Z operator (#127259)
-- fixed non-greedy backtracking bug (#123769, #127259)
-- added sre.DEBUG flag (currently dumps the parsed pattern structure)
-- fixed a couple of glitches in groupdict (the #126587 memory leak
   had already been fixed by AMK)

Fredrik Lundh e186983842 final 0.9.8 updates:

Fredrik Lundh 29c4ba9ada SRE 0.9.8: passes the entire test suite
-- reverted REPEAT operator to use "repeat context" strategy
   (from 0.8.X), but done right this time.
-- got rid of backtracking stack; use nested SRE_MATCH calls
   instead (should probably put it back again in 0.9.9 ;-)
-- properly reset state in scanner mode
-- don't use aggressive inlining by default

Fredrik Lundh 7cafe4d7e4 - actually enabled charset anchors in the engine (still not
used by the code generator)

- changed max repeat value in engine (to match earlier array fix)

- added experimental "which part matched?" mechanism to sre; see
  http://hem.passagen.se/eff/2000_07_01_bot-archive.htm#416954
  or python-dev for details.

Fredrik Lundh 3562f11764 -- use charset bitmaps where appropriate. this gives a 5-10%
speedup for some tests, including the python tokenizer.

-- added support for an optional charset anchor to the engine
   (currently unused by the code generator).

-- removed workaround for array module bug.
