if a single text file name is supplied as argument
(e.g.: 'webpmux my_long_list_of_frames.txt'), the command
line arguments are actually parsed from this file.
Tokenizer will remove space, tabs, LF, CR, returns, etc.
+ changed ImgIoUtilReadFile() to return a null-terminated
data, for convenience.
+ misc clean-up in the code
BUG=webp:355

The options are now:
-duration d -> set the whole animation to duration 'd'
-duration d,s -> set only frame 's' to duration 'd'
-duration d,s,e -> set only interval [s,d] to duration 'd'
+ style fix

this will force a constant duration for an interval of frames
in an animation.
Notes:
a) '-duration [...]' can be repeated as many times as needed.
b) intervals are taken into account in option order. If they overlap, values will be overwritten.
c) 'start' and 'end' can be omitted, but not the duration value.
d) 'end' can be equal to '0', in which case it means 'last frame'
e) single-image files are untouched (ie. not turned into an animation file).
Some example usage:
webpmux -duration 150 in.webp -o out.webp
webpmux -duration 33,10,0 in.webp -o out.webp
webpmux -duration 200,2 -duration 150,0,50 in.webp -o out.webp

decoding and file i/o have been split to imageio, all that remains is
some string routines used for parameter parsing in the examples
Change-Id: I77386cd8aa39124b9e14c95fdbaa17ea4ab5bb24
put WebPMuxConfig on the stack in main() rather than allocating it in
InitializeConfig(); removes a level of indirection there.

this change has the side-effect of using directory names in the
include, silencing a lint warning.
Change-Id: Ib91cf63a90534e32fadfa5c2372bfdb29f854d02
this enables webpmux to accept input files starting with '-' when using
-get/-set/-strip; -info & -frame expect an input file as one of their
parameters so no changes are necessary there.

rather than symlink the webm/vpx terms, use the same header as libvpx to
reference in-tree files
based on the discussion in:

They went out of sync some time ago, and are
no longer really required since we have them
buildable from makefile.unix
Change-Id: Ica2dcf5c55f44365598f832f55204d123d7aa601
this would require a PRIuS or similar macro for proper platform
compatibility (Visual Studio for instance would be variants of %lu)

Now, its: +duration+xoffset+yoffset+disposal
+disposal can be omitted and will default to +0 (NONE)
additionally, +xoffset+yoffset can be omitted and will default to +0+0
Change-Id: I62138c9f675d4fc4408305babbcd485cb32b73d3
- Allow a duration of 0
- Rename LOOP chunk to ANIM and add the background color field to it.
- Add a disposal method field for each animation frame.
- Modify webpmux.c binary interface to allow the input of background color
and disposal methods. Also make '-loop' and '-bgcolor' arguments optional
with some default values.
