7a2b6e1301 libfreerdp-core: fix reading TS_ICON_INFO
The spec says that CbColorTable field is present when Bpp is 1, 4, 8.
Actually, bpp == 2 is not supported by TS_ICON_INFO according to the
spec (though, DIB definitely supports 16-color images).

    MS-RDPERP 2.2.1.2.3 Icon Info (TS_ICON_INFO)

    CbColorTable (2 bytes):
        This field is ONLY present if the bits per pixel (Bpp)
        value is 1, 4, or 8.

Omitting 8-bit value breaks 256-color icons which are incorrectly
read with color and alpha data mixed up.

e7cd3250c3 Fix a regression introduced with PR #4013
If numWindowRects/numVisibilityRects is zero a realloc might either
return NULL or a free able memory. In the first case the introduced
regression caused a double free.
As 0 is a possible value that can be received in both cases rail was
broken.

Fixes #4022

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
