[#MDEV-4616] Crash after InnoDB: Error: io_setup() failed with EAGAIN after 5 attempts is back

There was a good fix in 5.5 that disabled Linux Native AIO in case of a problem, instead of making the server crash on startup:

timestamp: Wed 2012-06-27 17:13:12 +0300

message:

  Don't abort InnoDB/XtraDB if one can't allocate resources for AIO

  - Better error messages

  This fixes that one again can run the test systems with many threads without having to increase fs.aio-max-nr.

In current 10.0 the fix for XtraDB (which is basically 5.5) is still present, but for InnoDB it disappeared, apparently after the previous merge.
Please add it back when the next merge is finished.
