during the elimination of %inlined symbols.

MenhirLib remains under LGPL with a linking exception.
MenhirSdk is considered part of the Generator.
Updated the header of every source file under version control.

Attributes are propagated through the expansion of parameterized symbols,
at which time %attribute declarations are also desugared.
Inlining is easy (an %inline callee or caller cannot carry attributes).

declarations for symbols that are inlined away (and warning about
them, at the same time).

provided it appears in tail position in its caller and
its caller does not itself have a %prec annotation.

that is, before %inlining.

production is epsilon and is inlined in front.
With this change, %inline seems to preserve positions!

Now supported by the table back-end.

Only in internal form, for now -- does not exist in concrete syntax.
Not yet supported by the back-ends.

Cleanup in [NonTerminalDefinitionInlining], and the beginning of a new way of translating positions when %inlining. Unfinished.

and [rename_sw_inner] to [Nonterminaldefinitioninlining], where they
belong.

It passes.
This will allow some serious simplification.

   If the programmer did not provide a name [_i] is used (where [i] is
   the producer's position in the right hand side).

   This syntax modification actually simplifies the code:
   - There is no more on-the-fly naming of unnamed arguments.
   - Inlining is no more restricted to semantic actions that do not use $i.

   The patch is large because:
   - This change has an impact on many modules.
   - The expected results of the bench had to be updated.
