vo_sixel: Add aspect ratio based output centering

Resize the image based on the dimensions reported by
vo_get_src_dst_rects to correctly handle aspect ratio
that might be set/ignored.

Added pad-x and pad-y options for padding.
These options will be used to remove the extra padding.
Some terminals report the padding of 2px in the ioctl
dimensions which can't be used for displaying sixel
output. These options can be used for fine tuning
the output video resolution.

Now all the terminal size detection and calculation logic
is done in a single function at resize. Also top and left
values are computed from the dst_rect parameters to simplify
the logic for the aspect ratio based centering.

Additionally vo-sixel-rows and vo-sixel-cols options
have been added to enable the user to override the values
in case of failures with get_terminal_size2.

This commit also adds ability to handle video zoom correctly.
Whenever video-zoom is triggered, the src and dst rects
will be updated. Scaling seems to work well now.
