9fb6766870 pngenc: add support for 8- and 16-bit gray images 
Add support for direct encoding of 8- and 16-bit big endian gray images.

38372eb199 pngdec: add support for video/x-raw-gray formats 
pngdec can now decode gray 8- and 16-bit images without alpha channel
direct to video/x-raw-gray format. 16-bit gray images have big-endian
format, because it's native PNG endianness. Gray images with alpha
channel still converted to RGBA.

41116224c8 pngenc: increase arbitrary resolution limits 
Apparently libpng can technically do up to 2^31-1 rows and columns. However it
imposes an (arbitrary) default limit of 1 million (that could theoretically be
lifted by using some additional API).

Moved array allocation to the heap now.

65f9354803 pngenc: ensure setcaps was called before chain function

7e390c4635 pngenc: validate input buffer size

9eb55c3d8f pngenc: make setcaps more robust, use gstvideo functions 
A setcaps function needs to actually verify the caps carefully. In this case,
it was possible to e.g. link a video decoder with YUV+RGB template caps to
pngenc.  That would cause a crash when the decoder pushes a YUV buffer. Same
thing when pushing a valid buffer that exceeds the resolution limits.

Also, missing framerate caps field would cause a glib critical warning due to
invalid GValue. This fails hard now.

2514421c13 png: fix compilation with libpng 1.4 
png_set_gray_1_2_4_to_8() has been deprecated for a while and was
finally removed in libpng 1.4.x. Use png_set_expand_gray_1_2_4_to_8()
instead.

Fixes #608629.

d9544bcc44 pngdec: Avoid possible overflow in calculations 
A malformed (or simply huge) PNG file can lead to integer overflow in
calculating the size of the output buffer, leading to crashes or buffer
overflows later. Fixes SA35205 security advisory.
