fix(frontends/lean, library/tactic): remove redundant error messages, and fix position of error messages
...
Summary:
We minimize the number of "'sorry' used warning messages". We also
re-target the error to the main declaration. Example: foo._main ==> foo
We do not report for auxiliary declarations such as "_example" and
"foo.equations._eqn_1"
Get rid of the redundant error message "error : failed" for tactics.
We added "silent failures" in the tactic framework.
We do not store line/col information for tactics nested in notation
declarations. Before this commit, we would have tactics such
as (tactic.save_info line col) nested inside of notation declarations.

We can now elaborate
https://gist.github.com/gebner/439273deee592603190d4f8b4447295b
in 1.6 secs and using less than 500Kb of stack space.
It was takins 44 secs and 5Mb before this commit.
Two modifications:
1) Use pre_monad.seq instead of pre_monad.and_then.
They have the same implementation, but seq is not marked as [inline].
2) Modify how we concatenate the tactics in a begin...end block.
Before: (((a_1 ++ a_2) ++ a_3) ++ a_4)
After: ((a_1 ++ a_2) ++ (a_3 ++ a_4))
