Use workaround for Bug#24507 only if glibc version is older than 2.6, otherwise it will just be a overhead.

Since posix_fallocate is more portable than fallocate, adding a check for its
existence and to use it, if fallocate doesn't exist.

since fsync causes ENOLCK only on old FreeBSD systems.

MySQL crashes when AIO is attempted on a file whose underlying media doesn't
support it. This is true for tmpfs on kernel < 2.6.22 and other
filesystems/devices where AIO may be undefined. So, with this patch, it will try
to use simulated aio if the native aio fails (only for that file/table).
innodb_use_native_aio doesn't help if only a few tables need to have AIO and
rest don't.

Should fix http://bugs.mysql.com/bug.php?id=58421. Also, discussed here
