f814d224f7 Critical fixes after review: 
- mutex was unlocked before the end of the critical sesion,
- Portability issue: It's better to use (*alloc)(x) instead of alloc(x),
  if alloc is a function passed as an argument.
- Use {} around if() block, to avoid possible problems with some Windows compilers.

f207b33a7b Support for character set conversion in binary protocol: another go 
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
  connection on the fly, because they first should be written to the binary
  log.
  To support efficient conversion we need to rewrite prepared statements
  binlogging code first.

ebc3b3afac BTREE-indexes in HEAP tables can now be used to optimize ORDER BY 
Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files
Compare strings with space extend instead of space strip. Now the following comparisons holds:  "a" == "a " and "a\t" < "a". (Bug #3152).
Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns.
