MdePkg 相关Lib
MdePkg\Include\Library
edk2-stable202105目前为止MdePkg一共声明了67个头文件
UnitTestHostBaseLib|Test/UnitTest/Include/Library/UnitTestHostBaseLib.h比较特殊，放在Test文件夹下，其余都在Include/Library路径下
dec文件中LibraryClasses项中会声明相应的Lib和其包含路径的对应的头文件，规范起见一般统一放在Include/Library路径下，一般来说LibraryClassesName和头文件*.h会取相同的命名，有些LibraryClasses不是common的，和架构有关，需要通过[LibraryClasses.IA32, LibraryClasses.X64, LibraryClasses.AARCH64]来指明Lib可以在那些架构中使用,例如SMM SMI只适用于IA32 X64架构
dec中定义了LibraryClassesName，并且和Include\Library中声明的头文件关联起来了，对应的LibraryInstance放在Library文件夹下，一般为了统一取的文件夹名也是和LibraryClassesName相同，最后LibraryClasses Mapping的时候会将dec中声明的Lib和实现的LibraryInstance Module的inf对应上，会出现dec出现的Lib，dsc中没有对应，猜想应该是只想共本Pkg调用，所以未对外暴露接口
LibraryClasses中声明的接口对应的实现我们叫做LibraryInstance，这个会包在dsc文件里的Components中，实现也是和架构有关的，所以会卡[Components.IA32, Components.X64, Components.ARM, Components.AARCH64]的条件，主要看这个实现部分在对应的架构能不能被用
一般来说，一个LibraryClass的LibraryInstance可能有多个，常见的如CpuLib有两个Instance，一个为Null，那就对应Library/BaseCpuLib和Library/BaseCpuLibNull两个文件夹，还有就是不同Phase有不同的实现，例如BaseMemoryLib对应Library/BaseMemoryLib，Library/BaseMemoryLibMmx，Library/BaseMemoryLibOptDxe，Library/BaseMemoryLibOptPei，Library/BaseMemoryLibRepStr，Library/BaseMemoryLibSse2这几个文件夹下对应的inf的LibraryInstance，还有就是instance跨Pkg的情况，一般lib都是本Pkg声明和实现，但不绝对，其中MemoryAllocationLib是在MdePkg声明的，但存在instance在MdeModulePkg，DxeCoreMemoryAllocationLib.inf
PiSmmCoreMemoryAllocationLib.inf,类似的还有SmmServicesTableLib.h，HobLib.h
