Changing 'inaccessible' to 'unreachable' to be consistent with BI-AAG

Incorrect (unparseable) commands were not saved into history. When this
happens usually you want to quickly fix the mistake and run again. But
the command was not saved to history so we were unable to do that.

Remove all references to old parser in tests.
Replace AST comparasion with generated files from old parser
which are same as from the new parser.

Tests for parser are now under one test_case and are dynamicly loaded
at runtime. Thanks to that we have only one compilation unit.

It also simplifies CMake for alib2cli

Remove all logic related to handling of command scope from visitor.
The handling is done in the grammar and in the parser.
No tricks with parser actions are used.

This commit contains two fixes. One for introspect of bindings, where
we only accept identifier or integer (valid bindings names), which is
different form old parser.

The second change is fix of completion of bindings when used.

Also create own syntax rule for each data type (String, Integer, Double).
This makes parsing simplier as we do not have to check if the node with one
type is present and the ANTLR runtime will do it for use.

LineInterface in AQL2 was required beacuase of old parser.
With new parser, it is not required anymore. However, we still need
some kind of abstraction over user input, and so we introduce Interface,
which is simplier, than old LineInterface.

New parser does not support passing raw path, thus we need to have it
as a string
