fixed toaster-eventreplay (#9585)

Hi,

This patchet contains changes made to toaster-eventreplay script to make it working with the recent codebase.

Most of the changes were caused by moving to Python 3. Old event serializing code in cooker and toaster-eventreplay doesn't work in Python 3.

There were also changes made to toasterui and buildinfohelper that made the script outdated, e.g. setEventMask was used in toasterui, but was not implemented in toaster-eventreplay.

Test instructions:
- generate event file using bitbake -u knotty -w events core-image-minimal
- start toaster: . ../bitbake/bin/toaster start
- check the the latest build:
../bitbake/lib/toaster/manage.py shell
In [1]: from orm.models import Build
In [2]: Build.objects.last()
Out[2]: <Build: 58 Project object core-image-minimal>
- replay event file: toaster-eventreplay events
- make sure latest build number is incremented:
../bitbake/lib/toaster/manage.py shell
In [1]: from orm.models import Build
In [2]: Build.objects.last()
Out[2]: <Build: 59 Project object core-image-minimal>

Note: This patchset depends on recent changes to cooker code:

The following changes since commit 94dd70f042cd750a44ddfcef879a9547b072788f:
