Implement jump-till-matching-bracket input function

Browse Source 
Part of #1842

It's like jump-to-matching-bracket, but jumps right before the bracket

I will use it to mimic vi 'ab' and 'ib' text objects in the next commit

Given complicated semantics of jump-till-matching-bracket, an alternative name
could be 'jump-inside-matching-brackets'. But that would make names non-symmetrical.
I'm not sure what is worse.

otherwise, jump to the next occurence of *any right* bracket after the cursor.
The following brackets are considered: ``([{}])``
``jump-till-matching-bracket``
the same as ``jump-to-matching-bracket`` but offset cursor to the right for left bracket, and offset cursor to the left for right bracket.
The offset is applied for both the position we jump from and position we jump to.
In other words, the cursor will continuously jump inside the brackets but won't reach them by 1 character.
The input function is useful to emulate ``ib`` vi text object.
The following brackets are considered: ``([{}])``
``kill-bigword``
move the next whitespace-delimited word to the killring
