these are only used in the encoder.

Precalculated block ptrs do not need updates during encoding.
Set these at init stage.
Moved the allocation of 'mt_current_mb_col' (last encoded MB on each
row) to vp8_alloc_compressor_data(), so that it is correctly
reallocated when frame size is changing.

xd->subpixel_predict16x16 is called in first pass, but isn't
initialized in first pass, which causes segfault. This patch
fixed that problem.

Allows building the library with the gcc -pedantic option, for improved
portabilty. In particular, this commit removes usage of C99/C++ style
single-line comments and dynamic struct initializers. This is a
continuation of the work done in commit 97b766a46, which removed most
of these warnings for decode only builds.

Make functions only referenced from one translation unit static. Other
symbols with extern linkage get a vp8/vpx prefix.

Change If4321cc5 fixed a bug caused by forward declarations not being
kept in sync across C files, resulting in a function call with the
wrong arguments. The commit moves the affected function declarations
into a header file, along with the other symbols from encodeframe.c
that were being sloppily shared.

Removes all runtime initialization of global data. This commit is a
squashed version of the following series cherry-picked from master.
This is necessary because of a change that was merged to the tester
that depends on the scaler being moved to the RTCD framework, which
is a worthwhile thing to include in Eider anyway.
- a91b42f02 Makes all global data in entropy.c const
- b35a0db0e Makes all global data in tokenize.c const
- 441cac8ea Makes all mode token tables const
- 5948a0210 Ports vpx_xcaler to new RTCD method
- 317d4244c Makes all mode token tables const part 2

This change added a motion search skipping mechanism similar
to what we did in second pass. For a macroblock that is very
similar to the macroblock at same location on last frame,
we can set its mv to be zero, and skip motion search. This
improves first-pass performance for slide shows and video
conferencing clips with a slight PSNR loss.

This commit continues the process of converting to the new RTCD
system. It removes the last of the VP8_ENCODER_RTCD struct references.

The total_stats, this_frame_stats, and total_left_stats structures
were previously create by a heap allocation, despite being of fixed
size. These structures were allocated and deallocated during
{de,}allocate_compressor_data, which is reinvoked whenever the frame
size changes. Unfortunately, this clobbers the total_stats and
total_left_stats data.
Historically, these were variable size at one time, due to the first
pass motion map, which necessitated their being created by a unique
heap allocation. However, this bug with the total_stats being
clobbered has probably been present since that initial implementation.
These structures are instead moved to be stored within the struct
twopass_rc directly, rather than being heap allocated separately.
