Implemented support to ignore an attempt to install/load a particular ACPI table more than once. Apparently there exists BIOS code that repeatedly attempts to load the same SSDT upon certain events. Thanks to Venkatesh Pallipadi. Restructured the main interface to the AML parser in order to correctly handle all exceptional conditions. This will prevent leakage of the OwnerId resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some machines. Thanks to Alexey Starikovskiy. Support for "module level code" has been disabled in this version due to a number of issues that have appeared on various machines. The support can be enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem compilation. When the issues are fully resolved, the code will be enabled by default again. Modified the internal functions for debug print support to define the FunctionName parameter as a (const char *) for compatibility with compiler built-in macros such as __FUNCTION__, etc. Linted the entire ACPICA source tree for both 32-bit and 64-bit.
