The EFI System Table contains pointers to the runtime and boot services tables.
As the system_table may grow with new UEFI versions, it is important to check hdr.header_size.
After successfully calling boot_services.exitBootServices, console_in_handle, con_in, console_out_handle, con_out, standard_error_handle, std_err, and boot_services should be set to null. After setting these attributes to null, hdr.crc32 must be recomputed.
