Import acpidump from FreeBSD per request from jmcneill@
Changes made in the port: - adapt path to iasl from /usr/sbin/iasl to /usr/bin/iasl - fix realpath() usage to accomplish NetBSD's behaviour - use EXIT_FAILURE/EXIT_SUCCESS everywhere - fix crash on corrupt DSDT file and print proper error message - implemented additional ACPI table parsers for BERT, BOOT, CPEP, DBGP, EINJ, ERST, HEST, MSCT, SBST, SLIT, SPCR, TCPA, WAET, WDAT and WDRT
