ec8257216e Enhancement: Change atomic_writes table option to enum type. Now every file can either use atomic writes, not use it or use default.
SYNTAX: ATOMIC_WRITES=['DEFAULT','ON','OFF']

Idea here is to be able to define innodb_doublewrite = 1 but with following rules:

ATOMIC_WRITES='DEFAULT' - if innodb_use_atomic_writes = 1, we do not write to doublewrite buffer the changes
                          if innodb_use_atomic_writes = 0, we write to doublewrite buffer
ATOMIC_WRITES='ON'      - do not write to doublewrite buffer
ATOMIC_WRITES='OFF'     - write to doublewrite buffer

Note that doublewrite buffer can't be used if innodb_doublewrite = 0.

5e55d1ced5 Changes for Fusion-io multi-threaded flush, page compressed tables and
tables using atomic write/table.

This is work in progress and some parts are at most POC quality.
