ACPICA: Clib: Eliminate acpi_os_XXXFile()/acpi_log_error and link clibrary fxxx()/errno/perror() instead 

ACPICA commit 189429fb7d06cdb89043ae32d615faf553467f1d

This patch follows new ACPICA design, eliminates old portable OSLs, and
implements fopen/fread/fwrite/fclose/fseek/ftell for GNU EFI
environment. This patch also eliminates acpi_log_error(), convering them
into fprintf(stderr)/perror(). Lv Zheng.
