Roman Penyaev a97ef36244 ui/console-vc: implement DCH (delete) and ICH (insert) commands 
This patch implements DCH (delete character) and ICH (insert
character) commands.

DCH - Delete Character:
   "As characters are deleted, the remaining characters between the
    cursor and right margin move to the left. Character attributes move
    with the characters. The terminal adds blank spaces with no visual
    character attributes at the right margin. DCH has no effect outside
    the scrolling margins" [1].

ICH - Insert Character:
   "The ICH sequence inserts Pn blank characters with the normal
    character attribute. The cursor remains at the beginning of the
    blank characters. Text between the cursor and right margin moves to
    the right. Characters scrolled past the right margin are lost. ICH
    has no effect outside the scrolling margins" [2].

Without these commands console is barely usable.
