class BBParsingStatus 变量含义

由于bitbake没有dev文档，code写的也没有多少注释，我只能通过这种方式来理解code
这是在class BBParsingStatus 中变量，我推测其中的含义

self.task_queues[file_name]内容：

do_listtasks:     []
do_rebuild:     []
do_compile:     ['do_configure']
do_configure:   ['do_unpack', 'do_patch']
do_stage:       ['do_compile']
do_build:       ['do_populate_staging', 'do_package', 'do_distribute_sources']
do_populate_staging:    ['do_package']
do_demo:        []
do_install:     ['do_compile', 'do_demo']
do_mrproper:    []
do_fetch:       []
do_unpack:      ['do_fetch']
do_patch:       ['do_unpack']
do_clean:       []
do_package:     ['do_install']
do_showdata:    []
do_distribute_sources:  ['do_fetch']
do_objclean:    []

self.task_deps[file_name]:
