If VerifyX509Certificate is set use it also when doing internal
certificate management. Added flags to ensure it is possible to
find out which type of connection is being made.
There is no point in using BIO_free with a custom recursion
to free up stacked BIOs if there is already BIO_free_all.
Using it consistently avoids memory leaks due to stacked BIOs
not being recursively freed.
The newly introduced option /tls-seclevel can be used to set the tls
security level on systems with openssl >= 1.1.0 or libressl.
As default level 1 is used as higher levels might prohibit connections
to older systems.
"(oid[0] << 4) & (oid[1] & 0x0F)" statement is always 0. It is not
problem currently because the only OID which is written by this
function should have 0 there. The function to read/write are pretty
limited anyway and can't work properly with all kind of OIDs. Maybe
it would be better to hardcode the OID there without decoding
and encoding. But those functions are already there so let's improve
them a bit according the spec and warn about limited set of
supported OIDs.

This option will ensure that NLA is disabled(since NTLM uses weak crypto algorithms), FIPS
encryption is enabled, and ensure fips mode is enabled for openssl.
Selectively override specific uses of MD5/RC4 with new API calls specifically tailored to override FIPS.
Add comments on why overriding the use of these algorithms under FIPS is acceptable for the locations where overrides happen.
Remove check of server proprietary certificate which was already being ignore to avoid use of MD5.
Initialize winpr openssl earlier to ensure fips mode is set before starting using any crypto algorithms.
[libfreerdp/crypto/certificate.c:315] -> [libfreerdp/crypto/certificate.c:316]: (warning) Either the condition 'if(fingerprint&&fprint)' is redundant or there is possible null pointer dereference: fingerprint.
- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
- 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
If a target is linked against libraries with cmake
(target_link_libraries) and the libraries are not marked as PRIVATE
they are "exported" and in case a other target is linked against this
target it is also linked against *all* (not private) libraries.
Without declaring private libraries PRIVATE a lot of over linking
(linking against unneeded libraries) was done.
When nothing is declared, only export symbols defined
with WINPR_API or FREERDP_API defined.
Override this setting if BUILD_TESTING to allow tests
access to internal functions usually not exposed.
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
Sometime it's possible that your server application doesn't have access to files
(when running in a very restricted environment for example). This patch allows
to ship the private key and certificate as a string.

Currently TLS version 1.0 is used implicitly by using the TLSv1_method.
To be able to also use TLS 1.1 and later use SSLv23_client_method
instead. To make sure SSLv2 or SSLv3 isn't used disable them.
