7f5f40d392 core/nla: use RedirectionPassword if set in settings
Previously, the code prompted for the password even if a RedirectionPassword
was provided.

With this change the prompt is only shown if both settins->Password and
settings->RedirectionPassword is absent.

4bfb4dddbf Add a callback to provide NTLM hashes on server-side
Adds a callback that allows servers to compute NTLM hashes by themselves. The typical
use of this callback is to provide a function that gives precomputed hash values.

a7f4685c09 Sec/NLA: Support passwordless (blank password) login with NLA.
It was supported in freerdp 1.0.2 but not supported in lastest master.
We should take empty password if it is explicitly specified with /v option.
If a password is not specified, we could first try SAM file. If the user entry does not exist, prompt for password.

18cea1c9ba Replaced cbMaxSignature with cbSecurityTrailer
The token buffer size during authentication was constructed
from the wrong buffer size. These sizes are equal in case of
local account logins but differ with domain accounts.

When using NULL credentials (current context)
the server state machine did not send back the
required authentication token.
On client side erroneous checks prevented sending

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
