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.

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

bdad9524dc refactor transport_read_pdu and check_fds 
transport_check_fds and transport_read_pdu had almost the same
functionality: reading and validating one pdu at a time.

Now transport_read_pdu reads one pdu from the transport layer and verifies
that the pdu data is valid - as before.
transport_read_pdu also ensures that the stream is sealed and
rewound when the pdu is received completely.
transport_check_fds just uses transport_read_pdu and does *not* do
the verification a second time based on the stream.

Besides the clean up this fixes the following problems:

* transport_read always read 4 bytes. Fast-path input synchronize pdus
  are only 3 bytes long. In this case on byte got lost in the stream
	buffer which lead to "de-synchronization" of server and
	client.

* Size check in tpdu_read_connection_confirm - already read bytes
  weren't taken into account.

47dd22ba87 transport refactor
