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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@5380 6f19259b-4bc3-4df7-8a09-765794883524

+ This program processes host environment variables and figures out
+ what the memory layout will be, how may FD's will be loaded and also
+ what the boot mode is.
+
+ The SEC registers a set of services with the SEC core. gPrivateDispatchTable
+ is a list of PPI's produced by the SEC that are availble for usage in PEI.
+
+ This code produces 128 K of temporary memory for the PEI stack by opening a
+ host file and mapping it directly to memory addresses.
+
+ The system.cmd script is used to set host environment variables that drive
+ the configuration opitons of the SEC.

+Module Name:
+
+ UnixThunk.c
+
+Abstract:
+
+ Since the SEC is the only program in our emulation we
+ must use a Tiano mechanism to export APIs to other modules.
+ This is the role of the EFI_UNIX_THUNK_PROTOCOL.
+
+ The mUnixThunkTable exists so that a change to EFI_UNIX_THUNK_PROTOCOL
+ will cause an error in initializing the array if all the member functions
+ are not added. It looks like adding a element to end and not initializing
+ it may cause the table to be initaliized with the members at the end being
+ set to zero. This is bad as jumping to zero will crash.
+
+
+ gUnix is a a public exported global that contains the initialized
+ data.
