ntlm: free target_info before (re-)malloc
OSS-Fuzz found a way this could get called again with the pointer still
pointing to a malloc'ed memory, leading to a leak.

Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=24379

Closes #5724

ntlm: enable NTLM support with wolfSSL
When wolfSSL is built with its OpenSSL API layer, it fetures the same DES*
functions that OpenSSL has. This change take advantage of that.

source cleanup: remove all custom typedef structs
- Stick to a single unified way to use structs
 - Make checksrc complain on 'typedef struct {'
 - Allow them in tests, public headers and examples

 - Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually
   typedef different types/structs depending on build conditions.

vauth/cleartext: fix theoretical integer overflow
Fix theoretical integer overflow in Curl_auth_create_plain_message.

The security impact of the overflow was discussed on hackerone. We
agreed this is more of a theoretical vulnerability, as the integer
overflow would only be triggerable on systems using 32-bits size_t with
over 4GB of available memory space for the process.

* Adjusted unit tests 2056, 2057
* do not generally close connections with CURLAUTH_NEGOTIATE after every request
* moved negotiatedata from UrlState to connectdata
* Added stream rewind logic for CURLAUTH_NEGOTIATE
* introduced negotiatedata::GSS_AUTHDONE and negotiatedata::GSS_AUTHSUCC
* Consider authproblem state for CURLAUTH_NEGOTIATE
* Consider reuse_forbid for CURLAUTH_NEGOTIATE
* moved and adjusted negotiate authentication state handling from
  output_auth_headers into Curl_output_negotiate
* Curl_output_negotiate: ensure auth done is always set
* Curl_output_negotiate: Set auth done also if result code is
  GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may
  also indicate the last challenge request (only works with disabled
  Expect: 100-continue and CURLOPT_KEEP_SENDING_ON_ERROR -> 1)

strerror: make the strerror function use local buffers
Instead of using a fixed 256 byte buffer in the connectdata struct.

In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.

This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.

spnego_sspi: add support for channel binding
Attempt to add support for Secure Channel binding when negotiate
authentication is used. The problem to solve is that by default IIS

urldata: rename easy_conn to just conn
We use "conn" everywhere to be a pointer to the connection.

Introduces two functions that "attaches" and "detaches" the connection
to and from the transfer.

Going forward, we should favour using "data->conn" (since a transfer
always only has a single connection or none at all) to "conn->data"
(since a connection can have none, one or many transfers associated with
it and updating conn->data to be correct is error prone and a frequent
reason for internal issues).

2873971d62 memory: ensure to check allocation results
The result of a memory allocation should always be checked, as we may
run under memory pressure where even a small allocation can fail. This
adds checking and error handling to a few cases where the allocation
wasn't checked for success. In the ftp case, the freeing of the path
variable is moved ahead of the allocation since there is little point
in keeping it around across the strdup, and the separation makes for
more readable code. In nwlib, the lock is aslo freed in the error path.

Also bumps the copyright years on affected files.
