The problem is aggravated by the presence of underlayment. When engineered hadrwood flooring was removed, some underlayment was removed with it, and some stayed glued to the floor.
What is the best way to remove all this mess? And should I use any solvent or adhesive remover?

I have had to go through this a few times recently. You can try hot water or some kind of remover but you may be making a liquid mess where you adhesive just spreads out.
I have found the fastest way of dealing with it is chiseling for a small area or power scraping - rent one or I personally own one that hooks up to compressor - scraper was like $15 at big box. Yes the work is more laborous but it gets done quicker and cleanup is with a broom.
