This patch enhances acpi_getopt() by converting the standard C library
invocations into portable ACPI string APIs and acpi_log_error() to improve
portability. Lv Zheng.

acpi_os_printf() to improve portability
This patch enhances ACPI_USAGE_xxx/ACPI_OPTION macros to use portable
acpi_os_printf() so that usage functions for applications no longer rely on
the printf() API.
To use acpi_os_printf() exported by osunixxf.c as a replacement of
printf(), applications need to initialize acpi_gbl_output_file to stdout
and initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. The
latter is automatically done by ACPI_INIT_GLOBAL(), applications need to
link utglobal.o to utilize this mechanism. For GCC, assigning stdout to
acpi_gbl_output_file using ACPI_INIT_GLOBAL() is not possible as stdout is
not a constant in GCC environment. As an alternative solution, stdout
assignment has been put into acpi_os_initialize(). Thus
acpi_os_initialize() need to be invoked very early by the applications to
initialize the default output of acpi_os_printf() to keep behavior
consistency.
acpidump has already invoked acpi_os_initialize() in this way. Lv Zheng.

This patch is mainly for acpidump where there are redundant
acpi_os_printf()/acpi_os_vprintf() stubs implemented. This patch cleans up such
specific implementation by linking acpidump to osunixxf.c/oswinxf.c.
To make acpi_os_printf() exported by osunixxf.c/oswinxf.c to behave as the
old acpidump specific ones, applications need to:
1. Initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT.
This is automatically done by ACPI_INIT_GLOBAL(), applications need to
link utglobal.o to utilize this mechanism.
2. Initialize acpi_gbl_output_file to stdout.
For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL()
is not possible as stdout is not a constant in GCC environment. As an
alternative solution, stdout assignment is put into acpi_os_initialize().
Thus acpi_os_initialize() need to be invoked very early by the
applications to initialize the default output of acpi_os_printf().
This patch also releases osunixxf.c to the Linux kernel. Lv Zheng.

acpi_ut_init_global() from utglobal.c to utinit.c
The utglobal.c is used to define and initialize global variables. It makes
sense if just adding utglobal.o to applications that are using such
variables. But acpi_ut_init_globals() is preventing us from doing so as
this initialization function references other components' initializations
code, which leads to the requirement that many files should also get linked
if one wants to link utglobal.o.
It is possible to just move acpi_ut_init_global() to utinit.c for
applications that require this function to link.
By linking utglobal.o, we can stop defining DEFINE_ACPI_GLOBALS for
applications (currently only acpidump is affected). Lv Zheng.

This patch adds "-x" and "-x -x" options to disable XSDT for acpidump.
The single "-x" can be used to stop using XSDT, RSDT will be forced to find
static tables, note that XSDT will still be dumped. The double "-x" can
stop dumping XSDT, which is useful when the XSDT address reported by RSDP
is pointing to an invalid address.
It is reported there are platforms having broken XSDT shipped, acpidump
will stop working while accessing such XSDT. This patch adds new option so
that users can force acpidump to dump tables listed in the RSDT. Lv Zheng.

The acpidump is initiated by Bob Moore and Chao Guan, fixed and completed
by Lv Zheng.
This patch is a generation of the commit that adds acpidump release
automation into ACPICA release process. Lv Zheng.
Note that this patch doesn't replace the kernel shipped acpidump with the
new acpidump. The replacement is done by further patches.

This patch cleans up old tools/power/acpi Makefile for further porting,
make it compiled in a similar way as the other tools. No functional
changes.
The CFLAGS is modified as follows:
1. Previous cc flags:
-Wall -Wstrict-prototypes -Wdeclaration-after-statement -Os -s \
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include
2. Current cc flags:
DEBUG=false:
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
-Wstrict-prototypes -Wdeclaration-after-statement -Os \
-fomit-frame-pointer
Normal:
-D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
-Wstrict-prototypes -Wdeclaration-after-statement -O1 -g -DDEBUG
There is only one difference: -fomit-frame-pointer.
