bump version to 1.0.5-dev
add upgrade action to sandbox.sh
don't copy so many mysql commands to sandbox directory

- only /usr/sbin/mysqld is known to cause issues with apparmor,
  and as we calculate mysqldump/mysqlupgrade relative to mysql
  this was causing problems with some sandbox.sh actions
Merge branch 'feature/sandboxsh_upgrade' into develop
update CHANGES

- noted changes for ./sandbox.sh upgrade
add sandbox user with plugin=mysql_native_password where available

- this resolves an issue when reloading mysql 5.5 data into a
  mysql 5.7.3 instance, where plugin='' automatically disables
  authentication.
updating CHANGES
Add minor comment to code that sets auth plugin
- This fixes issue #2
add documentation for ./sandbox.sh upgrade command

- this resolves issue #1
add check for libaio before downloading a distribution

- this check is restricted to mysql 5.5.4+ per mysql bug 60544.
  dbsake will attempt to locate aio via ctypes.util.find_library
  and abort if it is not available
add --skip-libcheck option to mysql-sandbox command

- resolves issue #3
handle mysql versions more robustly

- MySQLVersion.from_string now handles '-<tag>' in version names
  better to support 5.7.3-m13 or other tags that may come from
  other version sources
don't completely swallow stderr from mysqld --version

- when verifying the mysqld version, if this errors out, emit
  the stderr.  This mostly to fix issue #3, where missing libaio
  causes mysqld --version to fail, and the cause wasn't immediately
  obvious.
remove stale commented code from mysqld_version()
Merge branch 'feature/libaio_check' into develop
note libaio behavior change in CHANGES
tweak verbiage for uncaught exception
adjust filtering of mysql binary tarballs

- Now filter static libraries and embedded/debug binaries from ./bin
  Previously ./mysql-test ./sql-bench files were filtered
- Resolves issue #6
minor tweak to README verbiage
allow a directory to specified for --data-source

- If a directory is specified, dbsake will replace $sbdir/data with
  a symlink to the specified directory
- If a directory is specified, some "best effort" is done to check
  that datadir is not already in use by attempting a shared read
  lock on the ib_logfile0 file
