1) Sync EdkCompatibilityPkg with EDK 1.04. The changes includes:
1.1) Bug fixes. (For details, please check Documents & files: Snapshot/Release Notes at https://edk.tianocore.org/servlets/ProjectDocumentList?folderID=43&expandFolder=43&folderID=6) 1.2) Add new UEFI protocol definitions for AbsolutePointer, FormBrowser2, HiiConfigAccess, HiiConfigRouting, HiiDatabase, HiiFont, HiiImage, HiiString, SimpleTextInputEx, DPC protocol. 1.3) Add Smbios 2.5, 2.6 supports. Incompatible changes hilighted: 1) EFI_MANAGED_NETWORK_PROTOCOL_GUID changed. 2) EFI_IP4_IPCONFIG_DATA changed. 2) Add in EdkCompatibilityPkg/EdkCompatibilityPkg.dsc to build all libraries in this package. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4623 6f19259b-4bc3-4df7-8a09-765794883524
