reusing code of bridge calls in condenser_api

[Fix] get_account_reputations checks type of account_lower_bound parameter; also added default for limit (1000 - the same as it was in fat node)

[Fix] get_discussions_by_promoted reuse bridge_get_ranked_post_by_promoted* SQL functions (means code reuse + fix for paging and performance)

[Fix] get_post_discussions_by_payout reuse bridge_get_ranked_post_by_payout* SQL functions (means code reuse + fix for paging and performance); that required extra parameter to be able to turn off payout interval filter

[Fix] get_comment_discussions_by_payout reuse bridge_get_ranked_post_by_payout_comments* SQL functions (means code reuse + fix for paging and performance)

Old SQL implementations of above condenser_api calls removed.

[Fix] restored missing vote muting code in all above and more condenser_api calls
