Turn on OPENSSL_NO_DEPRECATED by default. Also introduce OPENSSL_USE_DEPRECATED. If OPENSSL_NO_DEPRECATED is defined at config stage then OPENSSL_USE_DEPRECATED has no effect - deprecated functions are not available. If OPENSSL_NO_DEPRECATED is not defined at config stage then applications must define OPENSSL_USE_DEPRECATED in order to access deprecated functions. Also introduce compiler warnings for gcc for applications using deprecated functions Reviewed-by: Rich Salz <rsalz@openssl.org>

This fixes the installation target for dynamic engines, which was trying to install to a different location than it had created. (BTW, VMS will need a matching fix in eng_list.c.) Note, these aren't ssl-specific, so I'm putting "engines/" into the libs directory rather than at the "--prefix" level or inside "ssl/".

Since opensslconf.h might be included over and over, undefine OPENSSL_UNISTD before redefining it, to avoid compiler warnings.

Some pre-POSIX systems don't have unistd.h (but e.g. lib.c). Allow configuring the name of that header file.

#undef OPENSSL_EXPORT_VAR_AS_FUNCTION
Introduce the possibility to access global variables through functions on platform were that's the best way to handle exporting global variables in shared libraries. To enable this functionality, one must configure with "EXPORT_VAR_AS_FN" or defined the C macro "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter is normally done by Configure or something similar). To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL in the source file (foo.c) like this: OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; OPENSSL_IMPLEMENT_GLOBAL(double,bar); To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: OPENSSL_DECLARE_GLOBAL(int,foo); #define foo OPENSSL_GLOBAL_REF(foo) OPENSSL_DECLARE_GLOBAL(double,bar); #define bar OPENSSL_GLOBAL_REF(bar) The #defines are very important, and therefore so is including the header file everywere where the defined globals are used. The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition of ASN.1 items, but that structure is a bt different. The largest change is in util/mkdef.pl which has been enhanced with better and easier to understand logic to choose which symbols should go into the Windows .def files as well as a number of fixes and code cleanup (among others, algorithm keywords are now sorted lexicographically to avoid constant rewrites).

RT3969: Add OPENSSL_SYS_UEFI This provides support for building in the EDK II reference implementation of UEFI. Most UEFI firmware in existence uses OpenSSL for implementing the core cryptographic functionality needed for Secure Boot. This has always previously been handled with external patches to OpenSSL but we are now making a concerted effort to eliminate those. In this mode, we don't actually use the OpenSSL makefiles; we process the MINFO file generated by 'make files' and incorporate it into the EDK2 build system. Since EDK II builds for various targets with varying word size and we need to have a single prepackaged configuration, we deliberately don't hard-code the setting of SIXTY_FOUR_BIT vs. THIRTY_TWO_BIT in opensslconf.h. We bypass that for OPENSSL_SYS_UEFI and allow EDK II itself to set those, depending on the architecture. For x86_64, EDK II sets SIXTY_FOUR_BIT and thus uses 'long long' for the 64-bit type, even when building with GCC where 'long' is also 64-bit. We do this because the Microsoft toolchain has 32-bit 'long'. Signed-off-by: Rich Salz <rsalz@akamai.com> Reviewed-by: Tim Hudson <tjh@openssl.org>
