    Fixed a problem in the AML parser where the method thread
    count could be decremented below zero if any errors
    occurred during the method parse phase. This should
    eliminate AE_AML_METHOD_LIMIT exceptions seen on some
    machines. This also fixed a related regression with the
    mechanism that detects and corrects methods that cannot
    properly handle reentrancy (related to the deployment of
    the new OwnerId mechanism.)
    
    Eliminated the pre-parsing of control methods (to detect
    errors) during table load. Related to the problem above,
    this was causing unwind issues if any errors occurred
    during the parse, and it seemed to be overkill. A table
    load should not be aborted if there are problems with
    any single control method, thus rendering this feature
    rather pointless.
    
    Fixed a problem with the new table-driven resource manager
    where an internal buffer overflow could occur for small
    resource templates.
    
    Implemented a new external interface, acpi_get_vendor_resource()
    This interface will find and return a vendor-defined
    resource descriptor within a _CRS or _PRS
    method via an ACPI 3.0 UUID match. (from Bjorn Helgaas)
    
    Removed the length limit (200) on string objects as
    per the upcoming ACPI 3.0A specification. This affects
    the following areas of the interpreter: 1) any implicit
    conversion of a Buffer to a String, 2) a String object
    result of the ASL Concatentate operator, 3) the String
    object result of the ASL ToString operator.
