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.

Unless something still comes up in review, the next step is merging.

Gerd, would you like to take it?

I'm busy going through the backlog (patches not merged during freeze)
anyway.  Queued this now.
