* Add anchor existant checking to link_checker component

* Handle name attributes

The access to translations is not straightforward and requires checks if
language and key exists. It is better to forbit direct access to
attribute and provide method - `get_translation()` - that will handle
all details of key translations.

Remove unit tests that use direct access and test only public method.

* fix the issue of generating the search index for multiple language

* updat docs for generating the search index for multiple language

* fix failed tests

* add tests for the search index of multiple language

Add method get_translation(lang, key) into Config struct that retrieves
translated term from parsed configuration or error when either
desired language or key is missing.

Use the new method in Trans struct implementing global Tera function
trans().

Add unit test to cover both happy and error path for translation
retrieval in both config and templates crate.

* Fix the issue when checking the changes of multiple language section

>3.2.0 has an updated onig version which requires llvm
which isn't built in azure pipelines in Windows

Closes #733

Closes #766

Closes #719

* Allow ignored_content to support markdown files

* Add test for markdown supported ignored_content

These functions expect that file_path can have base_path stripped from
it, but during reloading they can be given relative paths.  Maybe this
behaviour varies between the notify backends?

This fixes two zola serve panics on FreeBSD (poll backend).

Closes #756
