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.
