15f2bafeab Cleaned up const char** -> char** for argv, since we definitely do modify the argv!
(we overwrite the password and pin arguments).
This implies changes in the argument parsing tests that now must pass a mutable argv
(copied from the statically declared test argvs).
Some other const inconsistency have been dealt with too.

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.

53bd98883e winpr/crypt api changes and memory leak fixes
- winpr_HMAC_New() now just returnes the opaque WINPR_HMAC_CTX* pointer
  which has to be passed to winpr_HMAC_Init() for (re)initialization
  and since winpr_HMAC_Final() no more frees the context you always have to
  use the new function winpr_HMAC_Free() once winpr_HMAC_New() has succeded

- winpr_Digest_New() now just returns the opaque WINPR_DIGEST_CTX* pointer
  which has to be passed to winpr_Digest_Init() for (re)initialization
  and since winpr_Digest_Final() no more frees the context you always have to
  use the new function winpr_Digest_Free() once winpr_Digest_New() has succeded

333a1110f5 winpr/sspi/ntlm: fix computer name len calculation
The lpnSize parameter for GetComputerNameEx specifies the total
size of the buffer (in characters).
However, the current code calculated the amount of bytes.
Since only GetComputerNameExA was used and because sizeof(CHAR) == 1
the result was correct but the math was wrong.

26ed09a14f winpr/sspi/ntlm: fix GetComputerNameExA parameters
On input, the lpnSize [in, out] parameter for GetComputerNameEx()
specifies the total size of the buffer (in characters).
Several functions in ntlm.c were off by one which caused ntlm to fail
if the netbios hostname's strlen was exactly MAX_COMPUTERNAME_LENGTH.

95a1b53940 winpr/ntlm: Fix endianness in ntlm_av_pair_list
Data in ntlm_av_pair_list are accessed directly, which doesn't work on
big endian machines currently. The recieved data are stored as little
endian. Use conversion macros from endian.h to load and store the data
properly.

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

80958751e4 Add check to protect memcpy(3) from using NULL pointer.
The ntlm_construct_challenge_target_info function can potentially pass NULL as
argument to the ntlm_av_pair_add function (for example DnsDomainName.Buffer).
This NULL finally lands in the CopyMemory (which is macro to the memcpy(3)
function) which can't handle NULL.
