Port EdkUnixPkg to UnixPkg. The changes are listed as follows:

1. change *.msa to *.inf, and create platform configuration files .dec&.dsc&.fdf to comply with Edk2 build process
2. using PCD mechanism to replace macro.
3. change Sec code to cowork with PI1.0 Pei Core and produce temparory memory ppi.

+Abstract:
+
+  Produce block IO abstractions for real devices on your PC using Posix APIs.
+  The configuration of what devices to mount or emulate comes from UNIX 
+  environment variables. The variables must be visible to the Microsoft* 
+  Developer Studio for them to work.
