This impacts scheduling, because area meetings should not conflict with any
other session from their area. However, several area meetings have type WG,
and therefore look like ordinary WGs apart from meeting scheduling conflicts.
This new flag will allow distinguishing regular WGs from WGs whose meetings
must not conflict with anything else from their area.
The included migration sets this flag for the currently known area meetings:
dispatch, gendispatch, intarea, opsarea/opsawg, rtgarea, rtgwg, saag,
secdispatch, tsvarea, irtfopen
