Chessboard pattern prediction filter type search in non-RD coding

This commit introduces a chessboard pattern search for the prediction
filter type search. It runs extensive search in alternate blocks and
allows the rest blocks to refer coding decisions of their nearby
neighbors.

For pedestrian 1080p at 4000 kbps, the runtime of speed -5 goes down
from 43990 ms to 42200 ms. The overall compression performance for
RTC set is changed by -1.37%.

configure: quote some uses of source_path

doesn't completely fix configure/build in directories with spaces, but
it's good practice

Fixed handling of regularly placed keyframes

The encoder was not handling requests to place keyframes at
fixed intervals, i.e. kf_min_dist == kf_max_dist, correctly.

In this case when looking to place the next keyframe it was
accumulating stats all the way up to the end of the firstpass
file. This patch corrects this behavior.

Move shared test variables to tools_common.sh.

The global variables used in vpxdec.sh and vpxenc.sh have become useful
elsewhere: Define them in tools_common.sh instead.

Enable tests using WebM files only if webm_io is enabled

There are a few tests which read/write directly to/from WebM files. They should
be disabled when --disable-webm-io is passed.
