647ed7c78b digest: fix missing increment of 'nc' value for auth-int
- Increment nc regardless of qop type.

Prior to this change nc was only incremented for qop type auth even
though libcurl sends nc with any qop.

digest: unquote realm and nonce before processing
RFC 7616 (and 2617) requires values to be "unquoted" before used for
digest calculations. The only place where unquoting can be done
correctly is header parsing function (realm="DOMAIN\\host" and
realm=DOMAN\\host are different realms).

This commit adds unquoting (de-escaping) of all values during header
parsing and quoting of the values during header forming. This approach
should be most straightforward and easy to read/maintain as all values
are processed in the same way as required by RFC.

Closes #8912

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.

digest: Do not quote algorithm in HTTP authorisation
RFC 7616 section 3.4 (The Authorization Header Field) states that "For
historical reasons, a sender MUST NOT generate the quoted string syntax
for the following parameters: algorithm, qop, and nc". This removes the
quoting for the algorithm parameter.

snprintf: renamed and we now only use msnprintf()
The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

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.

1cafede9f2 rand: treat fake entropy the same regardless of endianness
When the random seed is purposely made predictable for testing purposes
by using the CURL_ENTROPY environment variable, process that data in an
endian agnostic way so the the initial random seed is the same
regardless of endianness.

- Change Curl_rand to write to a char array instead of int array.

- Add Curl_rand_hex to write random hex characters to a buffer.

f682156a4f Curl_rand: fixed and moved to rand.c
Now Curl_rand() is made to fail if it cannot get the necessary random
level.

Changed the proto of Curl_rand() slightly to provide a number of ints at
once.

Moved out from vtls, since it isn't a TLS function and vtls provides
Curl_ssl_random() for this to use.

a0f212946b vauth: Introduced Curl_auth_is_<mechansism>_supported() functions
As Windows SSPI authentication calls fail when a particular mechanism
isn't available, introduced these functions for DIGEST, NTLM, Kerberos 5
and Negotiate to allow both HTTP and SASL authentication the opportunity
to query support for a supported mechanism before selecting it.

For now each function returns TRUE to maintain compatability with the
existing code when called.
