* Added tests for freerdp_[static|dynamic]_collection_* functions
* Added settings unit test for clone functions
* Fix argument for winpr_RAND and winpr_RAND_pseudo
Using void* eliminates all assumptions of which type the buffer is.
This eliminates unnecessary warnings.
This partially reverts commit 67f3fff2. The legacy provider is now loaded
from the `winpr_InitializeSSL` function, so it is not needed to load it from
the `winpr_RC4_New` function again.
* winpr/crypto: Exit cleanly when EVP_EncryptInit_ex fails
The `EVP_EncryptInit_ex` function may fail in certain configurations.
Consequently, FreeRDP segfaults in `EVP_CIPHER_CTX_set_key_length`.
Let's handle the `EVP_EncryptInit_ex` failures and exit cleanly in
such case.
* winpr/crypto: Load legacy provider to fix rc4 with OpenSSL 3.0
Currently, the `EVP_EncryptInit_ex` function fails for rc4 with OpenSSL 3.0.
This is becuase rc4 is provided by the legacy provider which is not loaded
by default. Let's explicitly load the legacy provider to make FreeRDP work
with OpenSSL 3.0.

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.
SSL functions like OpenSSL_add_all_digests should be invoked at very beginning as they are not MT safe.

- 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
