- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments

The rdpContext gets an event which will
get set if an error occoured in a channel.
If a thread or a void callback has to report an
error it will get signaled by this system.
The function with the same name is defined in multiple libraries
(libfreerdp-shadow.so, libfreerdp-server.so), which might confuse
the dynamic linker at runtime, binding a wrong version of the function
and thus causing segmentation faults.
Since remdesk_virtual_channel_write()s aren't used outside the files
they are defined in, we can declare them static to make them invisible
to the linker.
