  branches/5.1: When the InnoDB and MySQL data dictionaries go out of sync, before
  the bug fix we would assert on missing autoinc columns. With this fix we allow
  MySQL to open the table but set the next autoinc value for the column to the
  MAX value. This effectively disables the next value generation. INSERTs will
  fail with a generic AUTOINC failure. However, the user should be able to
  read/dump the table, set the column values explicitly, use ALTER TABLE to
  set the next autoinc value and/or sync the two data dictionaries to resume
  normal operations.

  Fix Bug#44030 Error: (1500) Couldn't read the MAX(ID) autoinc value from the
  index (PRIMARY)

Enable functionality to have multiple background io helper threads.
This patch is based on percona contributions.

More details about this patch will be written at:
https://svn.innodb.com/innobase/MultipleBackgroundThreads

The patch essentially does the following:

expose following knobs:
innodb_read_io_threads = [1 - 64] default 1
innodb_write_io_threads = [1 - 64] default 1

deprecate innodb_file_io_threads (this parameter was relevant only on windows)

Internally it allows multiple segments for read and write IO request arrays
where one thread works on one segement.
