This patch adds a demo EFI application for stdin/stdout testing. This
utility can be used to narrow down root causes of porting issues. Lv Zheng.

This patch adds necessary build files for EDK2 environment to build ACPICA
tools.
The command steps of building edk2 binaries are (if you are using gcc4.7):
# cd edk2
# . ./edksetup.sh
# ln -s <path to acpica> AcpiPkg
# AcpiPkg/generate/efi/edksetup.sh
# build -p AcpiPkg/AcpiPkg.dsc -t GCC47
Note the above build test was done in Linux, and the Windows hasn't been
tested when this patch is generated. For building edk2 binaries in the MSVC
environment, you need to modify acpidump.inf, adding necessary options when
they cannot pass the build in the following configure items:
MSFT:*_*_IA32_CC_FLAGS/MSFT:*_*_X64_CC_FLAGS. Lv Zheng.

This patch follows new ACPICA design, eliminates old portable OSLs, and
implements fopen/fread/fwrite/fclose/fseek/ftell for GNU EFI
environment. This patch also eliminates AcpiLogError(), convering them
into fprintf(stderr)/perror(). Lv Zheng.

This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf()
support for OSPMs that have ACPI_USE_SYSTEM_CLIBRARY defined but do not
have ACPI_USE_STANDARD_HEADERS defined.
-iwithprefix include is required to include <stdarg.h> which contains
compiler specific implementation of vargs when -nostdinc is specified.
-fno-builtin is required for GCC to avoid optimization performed printf().
This optimization cannot be automatically disabled by specifying -nostdlib.
Please refer to the Link 1 for the details. Lv Zheng.

We've been using SHARED=false to capture unported stuff. However it can be
captured using -no-undefined. This patch removes SHARED option and adds
-no-undefined. Original by Marcelo Ferreira <joamarcelo@gmail.com>,

This change removes the _FORTIFY_SOURCE flag from the NOOPT disable option and
creates a separate flag (NOFORTIFY) for this purpose. Some toolchains may
define _FORTIFY_SOURCE which leads redefined errors when building ACPICA. This
allows disabling the option without also having to disable optimazations.

This patch adds generic OSL for GNU EFI shell development.
The following files are enhanced with GNU EFI builds:
1. os_specific/service_layers/osefixf.c
2. include/platform/acefi.h
Note that this patch only uses GNU EFI definitions and the following 2
implementations:
1. Linking GNU EFI entry point and we implements efi_main();
2. Linking DivU64x32 to perform division.
This is because:
1. We do not want to maintain architecture specific code in ACPICA, the
entry point and division implementation are architecture specific;
2. We do not want to define all EFI structures/macros again to inflate our
initial implementation. Since for non-architecture specific code, we
should try our best to implement our own to be more portable, we may
redefine these stuff in the future as they are not architecture
specific.
Note that linking DivU64x32() to implement ACPI_DIV_64_BY_32() can produce
correct division result for AcpiUtDivide(), but it is not performance
friendly as the two APIs have different meanings. This definitely will slow
down the applications. There is no architecture specific API in GNU EFI
that has implemented the same meaning as ACPI_DIV_64_BY_32(), so we have no
choice. Lv Zheng.

This patch adds build environment for GNU EFI shell development.
Note that only the Makefiles used by EFI development are created in this
patch, actual OSL is not implemented and ACPICA applications are enabled in
this patch. Lv Zheng.
