af9e394c8e Add Loader.source_dir attribute
Currently, Loader.source_path is used for both error locations and
as base for include directory.
But, it is set to "<expanded j2-yaml>" by !j2-yaml: tag, which makes it
unusable as base for include directory.
Make separate source_dir attribute for this usage.

af9e03ec08 Rewrite YAML parser
Rewrite YAML parser, YAML objects and parameters expansion logic to
enable better control over expansion logic.
Broken backward compatilibity:
* More agressive parameter expansion. This may lead to parameters
  expanded in places where they were not expanded before.
* Top-level elements, which is not known to parser (such as 'job',
  'view', 'project' etc), are now lead to parse failures.
  Prepend them with underscore to be ignored by parser.
* Files included using '!include-raw:' elements and having formatting in
  it's path ('lazy-loaded' in previous implementation) are now expanded
  too.
  Use '!include-raw-escape:' for them instead.
  See changes in these tests for examples:
    tests/yamlparser/job_fixtures/lazy-load-jobs-multi001.yaml
    tests/yamlparser/job_fixtures/lazy-load-jobs-multi002.yaml
    tests/yamlparser/job_fixtures/lazy-load-jobs001.yaml
* Parameters with template value using itself were substituted as is.
  For example: "timer: '{timer}'" was expanded to "{timer}". Now it
  leads to recursive parameter error.
  See changes in this test for example:
    tests/yamlparser/job_fixtures/parameter_name_reuse_default.*
    ->
    tests/yamlparser/error_fixtures/parameter_name_reuse_default.*
* When job group includes a job which was never declared, it was just
  ignored. Now it fails: job is missing.
  See changes in this test for example:
    tests/yamlparser/job_fixtures/job_group_includes_missing_job.*
    ->
    tests/yamlparser/error_fixtures/job_group_includes_missing_job.*
