de258fa8ca scripts: kernel-doc: fix parsing function-like typedefs (again) 
Typedefs like

    typedef struct phylink_pcs *(*pcs_xlate_t)(const u64 *args);

have a typedef_type that ends with a * and therefore has no word
boundary. Add an extra clause for the final group of the typedef_type so
we only require a word boundary if we match a word.

[mchehab: modify also kernel-doc.py, as we're deprecating the perl version]

04a383ced6 scripts/kernel-doc.py: Rename the kernel doc Re class to KernRe 
Using just "Re" makes it harder to distinguish from the native
"re" class. So, let's rename it.

16740c29db scripts/kernel_doc.py: better handle exported symbols 
Change the logic which detects internal/external symbols in a way
that we can re-use it when calling via Sphinx extension.

While here, remove an unused self.config var and let it clearer
that self.config variables are read-only. This helps to allow
handling multiple times in parallel if ever needed.

11afeab6d7 scripts/kernel-doc.py: Properly handle Werror and exit codes 
The original kernel-doc script has a logic to return warnings
as errors, and to report the number of warnings found, if in
verbose mode.

Implement it to be fully compatible with the original script.

e4b2bd908c scripts/lib/kdoc/kdoc_parser.py: remove a python 3.9 dependency 
str.removesuffix() was added on Python 3.9, but rstrip()
actually does the same thing, as we just want to remove a single
character. It is also shorter.

So, use it.

408269ae35 scripts/kernel-doc.py: fix handling of doc output check 
The filtering logic was seeking for the DOC name to check for
symbols, but such data is stored only inside a section. Add it
to the output_declaration, as it is quicker/easier to check
the declaration name than to check inside each section.

While here, make sure that the output for both ReST and man
after filtering will be similar to what kernel-doc Perl
version does.
