ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubs
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.
