1199380 (Resource leak). load_dsdt() calls strncpy() to copy a filename and Coverity warns that the destination buffer may not be NUL terminated. Fix this by using strlcpy() instead. If silent truncation occurs, then the filename was not valid anyway. load_dsdt() leaks an fd (CID 978405) and a memory region allocated using mmap() (CID 1199380) when it returns. Fix these by calling close() and munmap() as appropriate. Don't bother fixing the minor memory leak "list", allocated by AcGetAllTablesFromFile() (CID 1355191). Check for truncation when creating the temp file name. Set a flag to indicate that the temp file should be unlinked. Relying on a strcmp() test could delete the input file in contrived cases.
