ACPICA: acpidump: Add support to generate acpidump release.

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.

+ * Obtaining the system ACPI tables is an OS-specific operation.

+ * This utility can be ported to any host operating system by providing a

+ *      acpi_os_get_table_by_address
+ *      acpi_os_get_table_by_index
+ *      acpi_os_get_table_by_name

+ * See the ACPICA Reference Guide for the exact definitions of these
+ * interfaces. Also, see these ACPICA source code modules for example
+ * implementations:
+ *
+ *      source/os_specific/service_layers/oswintbl.c
