[PATCH v5 0/2] Option to take screenshot with screendump as PNG

[Kshitij Suri]

This patch series aims to add PNG support using libpng to screendump method.
Currently screendump only supports PPM format, which is uncompressed.

PATCH 1 phases out CONFIG_VNC_PNG parameter and replaces it with CONFIG_PNG
which detects libpng support.

PATCH 2 contains core logic for PNG creation from pixman using libpng. HMP
command equivalent is also implemented in this patch.

v4->v5
 - Modified format as a flag based optional parameter in HMP.

v3->v4
 - Added condition to check for libpng only in PNG option is allowed

v2->v3
 - HMP implementation fixes for png.
 - Used enum for image format.
 - Fixed description and updated QEMU support version.

v1->v2:
 - Removed repeated alpha conversion operation.
 - Modified logic to mirror png conversion in vnc-enc-tight.c file.
 - Added a new CONFIG_PNG parameter for libpng support.
 - Changed input format to enum instead of string.
 - Improved error handling.
