Changes between 3.0.0 and 3.0.1

* Fixed invalid handling of X509_verify_cert() internal errors in libssl        
   Internally libssl in OpenSSL calls X509_verify_cert() on the client side to   
   verify a certificate supplied by a server. That function may return a         
   negative return value to indicate an internal error (for example out of       
   memory). Such a negative return value is mishandled by OpenSSL and will cause 
   an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate  
   success and a subsequent call to SSL_get_error() to return the value          
   SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be         
   returned by OpenSSL if the application has previously called                  
   SSL_CTX_set_cert_verify_callback(). Since most applications do not do this    
   the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be     
   totally unexpected and applications may not behave correctly as a result. The 
   exact behaviour will depend on the application but it could result in         
   crashes, infinite loops or other similar incorrect responses.                 
                                                                                 
   This issue is made more serious in combination with a separate bug in OpenSSL 
   3.0 that will cause X509_verify_cert() to indicate an internal error when     
   processing a certificate chain. This will occur where a certificate does not  
   include the Subject Alternative Name extension but where a Certificate        
   Authority has enforced name constraints. This issue can occur even with valid 
   chains.                                                                       
   ([CVE-2021-4044])                                                             
                                                                                                                                               
                                                                                 
 * Corrected a few file name and file reference bugs in the build,               
   installation and setup scripts, which lead to installation verification       
   failures.  Slightly enhanced the installation verification script.                                                                      
                                                                                 
 * Fixed EVP_PKEY_eq() to make it possible to use it with strictly private       
   keys.                                                                         
                                                                                                                                   
                                                                                 
 * Fixed PVK encoder to properly query for the passphrase.
                                                                
                                                                                 
 * Multiple fixes in the OSSL_HTTP API functions.                                
                                                                                                                                         
                                                                                 
 * Allow sign extension in OSSL_PARAM_allocate_from_text() for the               
   OSSL_PARAM_INTEGER data type and return error on negative numbers             
   used with the OSSL_PARAM_UNSIGNED_INTEGER data type. Make                     
   OSSL_PARAM_BLD_push_BN{,_pad}() return an error on negative numbers.          
                                                                                                                                          
                                                                                 
 * Allow copying uninitialized digest contexts with EVP_MD_CTX_copy_ex.          
                                                                                                                                              
                                                                                 
 * Fixed detection of ARMv7 and ARM64 CPU features on FreeBSD.                   
                                                                
                                                                                 
 * Multiple threading fixes.                                                     
                                                                                                                                             
                                                                                 
 * Added NULL digest implementation to keep compatibility with 1.1.1 version.    
                                                                                                                                            
                                                                                 
 * Allow fetching an operation from the provider that owns an unexportable key   
   as a fallback if that is still allowed by the property query.
