* Use logging.Logger.warning instead of warning.warn in most cases, following
the Python official guidance that warning.warn is directed at _developers_,
not users
* (pdfdocument.py) remove declarations of PDFTextExtractionNotAllowedWarning,
PDFNoValidXRefWarning
* (pdfpage.py) Don't import warning, don't use PDFTextExtractionNotAllowedWarning
* (tools/dumppdf.py) Don't import warning, don't use PDFNoValidXRefWarning
* (tests/test_tools_dumppdf.py) Don't import warning, check for logging.WARN rather
than PDFNoValidXRefWarning
* get name right
* make flake8 happy
* Keep warning classes such that this does not crash code when these warnings are explictly ignored
* Update changelog to include pr ref
* Small textual change
* Remove patch
* No need for testing if the warning is actually raised. The test_tootls_dumppdf.py are just test cases if these pdfs are supported.
* Use logger as name for logger
* Add docs to legacy warnings
* Use logger.Logger.warn for failed decompression
* Add reference to docs describing when to use logger and warnings
