63e0b29291 pngdec: change parse logic
Right now in parse logic the signature is checked every time the parse function
is called, and the whole data is the scanned each and every time, even though the
data is scanned in the previous instance. Changing the logic such that, we skip
the bytes which are already scanned in the previous instances of parse. This
helps in avoiding multiple scan of already scanned data/signature.

e45e6382d6 pngdec: modify wrong packetized mode logic
packetized mode is being set when framerate is being set
which is not correct. Changing the same by checking the
input segement format. If input segment is in TIME it is
Packetized, and if it is in BYTES it is not.

b32de2794b pngdec: enable libpng interlaced picture handling
Makes libpng deinterlace Adam7 interlaced pictures
by default. It is the only interlaced format available
and if the picture isn't interlaced the code should behave
as before.

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.

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.
