Added support for atomic writes by disabling the doublewrite buffer. This is controlled by a new configuration variable innodb_use_atomic_writes. Added support for extending the database file using posix_fallocate and this is controlled by a new configuration variable innodb_use_posix_fallocate. Finally, added support to skip trim operation when page has actual write size initialized after fist successfull trim operation for this page and if initialized we do not trim again if actual page size does not decrease.
