Author: Stan Cox <scox@redhat.com>

    Add build id support for user modules.
    
    * sym.c (_stp_build_id_check): New.  Moved the build id check code from
     _stp_module_check and changed...
    (_stp_module_check): to use it.
    (_stp_usermodule_check): New.  This is called from the
    task manager callback stap_uprobe_change_plus for the process found and
    mmap found cases.
    
    * translate.cxx (dump_unwindsyms): Don't stop if it isn't a kernel module.
    Set build_id_vaddr for user modules.  Output module->build_id_offset as an
    absolute address.
    
    * uprobes-common.c (stap_uprobe_change_plus): Call _stp_usermodule_check.
