Port XtraBackup to Percona Server 5.5.9-beta20.1 codebase.

xtrabackup_55 is now based on Percona Server 5.5 rather than MySQL
5.5. Support for building against MySQL 5.5 and InnoDB plugin in MySQL
5.1 has been removed.

Therefore, the correspondence between build.sh targets and produced
binary is now as follows:

5.1 build against built-in InnoDB in MySQL 5.1
xtradb build against Percona Server with XtraDB 5.1
xtradb55 build against Percona Server with XtradB 5.5

Addendum to the patch for bug #606981.

Enclose the value of innodb_flush_method in double quotes when printing
out the configuration with --print-param. Otherwise innobackupex gets
confused when parsing the output and terminates with an error.

Bug #606981: linux + o_direct + stream backup = broken?

Streaming InnoDB files with tar4ibd could lead to filesystem hangs when
InnoDB was configured to access data files with the O_DIRECT flag. The
reason was that tar4ibd did not have support for O_DIRECT and
simultaneous O_DIRECT + non-O_DIRECT access to a file on Linux is

Fixed innobackupex and tar4ibd to use O_DIRECT on input InnoDB files if
the value of innodb_flush_method is O_DIRECT in the InnoDB configuration.

222. By Vadim Tkachenko

Disabled auto-creating of ib_logfile* when
innobackupex called with --redo-only or with --incremental-dir.

If neccessary ib_logfile* can be created later
with xtrabackup --prepare call.

LP bug #717784: Race condition in directory creation with parallel

Trying to check if directory exists before calling mkdir() is not safe
with multiple copying threads.

The fix is to try to create a directory without any checks instead and
then ignore the EEXIST error.
