glibc

bb2336170b fix potential overflow when width * height * 4 >= (1<<32)
Mostly: avoid doing calculation like: ptr + j * stride
when stride is 'int'. Rather use size_t, or pointer increments (ptr += stride)
when possible.

abdb109f3b add extra meaning to WebPDecBuffer::is_external_memory
If value is '2', it means the buffer is a 'slow' one, like GPU-mapped memory.

This change is backward compatible (setting is_external_memory to 2
will be a no-op in previous libraries)

dwebp:  add flags to force a particular colorspace format
new flags is:
   -pixel_format {RGB,RGBA,BGR,BGRA,ARGB,RGBA_4444,RGB_565,
                  rgbA,bgrA,Argb,rgbA_4444,YUV,YUVA}
and also,external_memory {0,1,2}
These flags are mostly for debuggging purpose, and hence are not documented.

4c60f63c64 make ReadPNG and ReadJPEG take a filename instead of a FILE
-> read is a bit slower (memory allocation and such) than reading directly from disk.

-> we're not yet ready to accept stdin as input (-- -) because we still need to guess
the file type with GetImageType(). And since we can't rewind on stdin, this will need
a bit more work before being able to read from stdin.

Lode Vandevenne
1f9be97c22 Make discarding invisible RGB values (cleanup alpha) the default.
Rename the flag to exact instead of the opposite cleanup_alpha. Add the flag to
WebPConfig. Do the cleanup in the webp encoder library rather than the cwebp
binary, this will be needed for the next stage: smarter alpha cleanup for
better compression which cannot be done as a preprocessing due to depending on
predictor choices in the encoder.

7861578bd6 for ReadXXXX() image-readers, use the value of pic->use_argb
This is to infer the needed conversion to YUV(A) or RGB(A).

This is useful to avoid some conversion steps between ARGB and YUVA.
For instance, if the input file is a JPEG, we decode to RGB and
convert to YUV right away, without the intermediate step to ARGB.

The only caveat is that cropping/scaling might give slightly different result,
because of YUV420 downsampling. Therefore, we omit this feature
at cwebp level, when -crop or -rescale is used.
