The current logic was storing symbols source code on a list,
not linked to the actual KdocItem. While this works fine when
kernel-doc markups are OK, on places where there is a "/**"
without a valid kernel-doc markup, it ends that the 1:1 match
between source code and KdocItem doesn't happen, causing
problems to generate the YAML output.
Fix it by storing the source code directly into the KdocItem
structure.
This shouldn't affect performance or memory footprint, except
when --yaml option is used.
While here, add a __repr__() function for KdocItem, as it
helps debugging it.

The test_kdoc_parser.py already supports loading dynamic tests
when running unit tests.
Add support to read from a different file. This is useful for:
- regression tests before/afer some changes;
- preparing new unit tests;
- test a different yaml before adding its contents at
tools/unittests/kdoc-test.yaml.
It should be noticed that passing an argument to a unit test
is not too trivial, as unittest core will load itself the
runner with a separate environment. The best (only?) way to
do it is by setting the system environment. This way, when
the class is called by the unit test loader, it can pick
the var from the environment without relying on a global
variable.
The unittest_helper has already provision for it, so let's
use its support.

Use the content of kdoc-test.yaml to generate unittests to
verify that kernel-doc internal methods are parsing C code
and generating output the expected way.
Depending on what is written at the parser file at
kdoc-test.yaml, up to 5 tests can be generated from a single
test entry inside the YAML file:
1. from source to kdoc_item: test KernelDoc class;
2. from kdoc_item to man: test ManOutput class;
3. from kdoc_item to rst: test RestOutput class;
4. from source to man without checking expected KdocItem;
5. from source to rst without checking expected KdocItem.

Validating that kernel-doc is parsing data properly is tricky.
Add an unittest skeleton that alllows passing a source code
and check if the corresponding values of export_table and
entries returned by the parser are properly filled.
It works by mocking a file input with the contents of a source
string, an comparing if:
- exports set matches;
- expected KernelItem entries match.
Create a new TestSelfValidate meant to check if the logic
inside KdocParser.run_test() does its job of checking for
differences inside KdocItem.
