strnxfrm for binary and simple charsets

of SHOW CREATE TABLE 'name'. Depending on the mode, the output can
be compatible with various databases, including earlier versions of
MySQL
.

Some function names have been renamed to be more self-descriptive

into sanja.is.com.ua:/home/bell/mysql/mysql-4.1

if charset is binary anymore

(Note: test 'union' fails, but Sanja promised to fix this)

This is to reuse code in conf_to_src.c

  Added some assertions to make sure index_init is only called with a properly prepared InnoDB table handle

  Fix InnoDB HANDLER: InnoDB must know in each call that the handle is used by HANDLER; the previous implementation worked only by pure luck

  Test allocation of memory beforehand if we are trying to return a > 2 MB BLOB; normally InnoDB asserts if memory allocation fails
ha_innodb.cc:
  Do not fetch all columns if change_active_index() is called during a query; a sum(a), max(a) query seemed to do that, doing unnecessary copying (the change actually made in the previous bk ci)
  Free BLOB heap of handle when MySQL calls some ::extra()'s

  Delete: mysys/xml.c
xml.c:
  Rename: BitKeeper/deleted/.del-xml.c~d20ceb97a91fcc2d -> mysys/xml.c

It is actually moved to /strings 

This is to reuse code to generate charset related C files
from ther descriptions written in XML files
