Test the 'size' images in the sequential reader. The existing test

Improved pngvalid coverage of filter combinations, remove the (new in 1.7)
|

code which disabled previous-row filters on the first row of an image in
|
||||
some cases.
|
||||
Removed all trailing spaces from source files in contrib
|
||||
Moved code round and changed the filter write interfaces that took
|
||||
png_uint_32 buffer pixel counts to unsigned int. Also moved compression
|
||||
code and definitions into pngwutil.c so that the compression code is
|
||||
isolated from other definitions.
|
||||
Unified the compression code so that inflate calls are localized to a common
|
||||
routine. Ground work for filter selection support. Minor API changes to
|
||||
use void* not byte* for data parameters. Unification of some of the
|
||||
compression code with the decompression code; IDAT_size replaces
|
||||
IDAT_read_size and zbuffer_size, IDAT reading and writing is no longer
|

controlled by the size of the compression buffer.
