commit 46994f71631922565924e3ca6303950c36337b33
Author: Richard Levitte <levitte at openssl.org>

    Add better support for using deprecated symbols internally
    
    OPENSSL_SUPPRESS_DEPRECATED only does half the job, in telling the
    deprecation macros not to add the warning attribute.  However, with
    'no-deprecated', the symbols are still removed entirely, while we
    might still want to use them internally.
    
    The solution is to permit <openssl/opensslconf.h> macros to be
    modified internally, such as undefining OPENSSL_NO_DEPRECATED in this
    case.
    
    However, with the way <openssl/opensslconf.h> includes
    <openssl/macros.h>, that's easier said than done.  That's solved by
    generating <openssl/configuration.h> instead, and add a new
    <openssl/opensslconf.h> that includes <openssl/configuration.h> as
    well as <openssl/macros.h>, thus allowing to replace an inclusion of
    <openssl/opensslconf.h> with this:
    
        #include <openssl/configuration.h>
    
        #undef OPENSSL_NO_DEPRECATED
        #define OPENSSL_SUPPRESS_DEPRECATED
    
        #include <openssl/macros.h>
    
    Or simply add the following prior to any other openssl inclusion:
    
        #include <openssl/configuration.h>
    
        #undef OPENSSL_NO_DEPRECATED
        #define OPENSSL_SUPPRESS_DEPRECATED
    
    Note that undefining OPENSSL_NO_DEPRECATED must never be done by
    applications, since the symbols must still be exported by the
    library.  Internal test programs are excempt of this rule, though.

+  *) Removed include/openssl/opensslconf.h.in and replaced it with
+     include/openssl/configuration.h.in, which differs in not including
+     <openssl/macros.h>.  A short header include/openssl/opensslconf.h
+     was added to include both.
+
+     This allows internal hacks where one might need to modify the set
+     of configured macros, for example this if deprecated symbols are
+     still supposed to be available internally:
+
+         #include <openssl/configuration.h>

+         #undef OPENSSL_NO_DEPRECATED
+         #define OPENSSL_SUPPRESS_DEPRECATED
+
+         #include <openssl/macros.h>
+
+     This should not be used by applications that use the exported
+     symbols, as that will lead to linking errors.
