If a platform doesn't include the TLS modules, such as - CryptoPkg/Library/TlsLib/TlsLib.inf - NetworkPkg/TlsAuthConfigDxe/TlsAuthConfigDxe.inf - NetworkPkg/TlsDxe/TlsDxe.inf then the platform never actually uses the libssl functionality that gets built into "OpensslLib.inf". Tomas Hoger from Red Hat Product Security tells me that security evaluation is less demanding if we can actually *exclude* the libssl files from such OVMF builds that don't specify -D TLS_ENABLE (rather than just trust modules not to call libssl functions if we don't specify -D TLS_ENABLE). This patch introduces a parallel OpensslLib instance called "OpensslLibCrypto" that is appropriate for platform builds without TLS enablement. It does not build C source files in vain, and it eases security review -- all libssl vulnerabilities can be excluded at once. "OpensslLibCrypto.inf" is created as a copy of "OpensslLib.inf", modifying the BASE_NAME, MODULE_UNI_FILE and FILE_GUID defines. "process_files.sh" is extended to auto-generate the list of OpenSSL files for both library instances accordingly. This list is updated in "OpensslLibCrypto.inf" at once. "OpensslLibCrypto.uni" is introduced as a copy of "OpensslLib.uni", highlighting the difference.
