6fd9525823 Implemented chroma subsampling for planar non RLE 
Planar frames that are not RLE encoded can now be decoded if
chroma subsampling is enabled. Partly fixes #5822

1112e2fffb codec: Set alpha channel to FF if not used (#5431) 
* Formatting

* codec: Set alpha channel to FF if not used

This PR initializes the alpha channel to FF. Before the alpha channel
contained uninitialized memory potentially causing problems when the
image data was used by an alpha channel aware frontend.

79d0725a80 codec/planar: Fix leak found by covscan 
The patch changes API of functions instead of fixing unused and broken code.

leaked_storage: Returning without freeing "outPlane" leaks the storage that it points to.

2e110c7f35 Fixed codec reset, now resetting resolution too. 
H264 and others require the surface resolution to work properly.
This initializes the codecs and the resolution on reset.

7c3f8f33ab Fixes for malloc / calloc + other fixes 
This patch contains:

* checks for malloc return value + treat callers;
* modified malloc() + ZeroMemory() to calloc();
* misc fixes of micro errors seen during the code audit:
** some invalid checks in gcc.c, also there were some possible
integer overflow. This is interesting because at the end the data are parsed
and freed directly, so it's a vulnerability in some kind of dead code (at least
useless);
** fixed usage of GetComputerNameExA with just one call, when 2 were used
in misc places. According to MSDN GetComputerNameA() is supposed to return
an error when called with NULL;
** there were a bug in the command line parsing of shadow;
** in freerdp_dynamic_channel_collection_add() the size of array was multiplied
by 4 instead of 2 on resize
