Thank you all for trying to help, but no one seems to understand what the question is about. None of those links have any information about running multi-SSID with ad-hoc and AP.
The point is that you can run mesh network with B.A.T.M.A.N or similar protocol in ad-hoc mode, but regular computer, phone etc. clients cannot connect to the mesh network as they understand nothing about the protocol. So you need a regular access point for them. With some chipsets it could be possible to run both with the same hardware simultaneously. That would be easier and less costly than using a second wireless AP or USB stick for regular clients.
Today I installed OpenWrt on a TP-Link TL-WR741ND rev. 1.9 and it's NOT POSSIBLE. It didn't even configure right and this is what I got in dmesg:
ath: Cannot create ADHOC interface when other interfaces already exist.
