Sometime it's possible that your server application doesn't have access to files
(when running in a very restricted environment for example). This patch allows
to ship the private key and certificate as a string.

Currently TLS version 1.0 is used implicitly by using the TLSv1_method.
To be able to also use TLS 1.1 and later use SSLv23_client_method
instead. To make sure SSLv2 or SSLv3 isn't used disable them.
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
If no entry for the <host> <port> combination
was found in the v2 file and there is a legacy file
check if a matching <host> entry can be found.
In case there is a matching entry and the <fingerprint>
also matches, create a new entry in the v2 file using the
current port.
Microsoft iOS Remote Desktop Clients eventually send NULL-terminated
hostnames in SNI which is not allowed in the OpenSSL implementation.
Since we're not using SNI this commit adds an OpenSSL TLS extension
debug callback which modifies the SSL context in a way preventing it
from parsing this extension
