Bug#27894: mysqlbinlog formats timestamp wrong in comment

Date stamps lack zero padding, and so are meaningless.

Implement minimum-width zero padding for the percent-escape sequences
used in the logging code.

	errno

Vasil Dimov (at Oracle) noted that pthread_key_create() does not
set errno, so if it fails then we return the wrong error code.

Instead, capture the return value, which is the real error value, 
and instead report that.

Fixes:

- Bug #26662: mysqld assertion when creating temporary (InnoDB) table on a tmpfs filesystem
  Fix by not open(2)ing with O_DIRECT but rather calling fcntl(2) to set
  this flag immediately after open(2)ing. This way an error caused by
  O_DIRECT not being supported can easily be ignored.
- Bug #23313: AUTO_INCREMENT=# not reported back for InnoDB tables
- Bug #21404: AUTO_INCREMENT value reset when Adding FKEY (or ALTER?)
  Report the current value of the AUTO_INCREMENT counter to MySQL.

NULL MERGE: this ChangeSet will be null merged into mysql-5.1
