Commit Message

sql: Limit number of terms in SELECT compoind stmts

Right now SQL query compiler is run on top of fiber's stack,
which is limited to 64KB by default, so maximum
number of entities in compound SELECT statement should be less than
50 (verified by experiment) or stack guard will be triggered.

In future we'll introduce heuristic which should understand that
query is 'complex' and run compilation in separate thread with larger
stack. This will also allow us not to block Tarantool while compiling
the query.

Closes #2548
