Major code formatting changes applied.

Struct discussion_query extended by select_metadata_tags and select_tags sets which participate
in tags selection by functions:

get_discussions_by_trending
get_discussions_by_promoted
get_discussions_by_trending30
get_discussions_by_created
get_discussions_by_active
get_discussions_by_cashout
get_discussions_by_votes
get_discussions_by_children
get_discussions_by_hot

Functions such as:

get_discussions_by_blog
get_discussions_by_feed

behaves exactly as seen in hardfork 16.3
