When reconstructing lines from a macro expansion, make sure that lines
at different levels in the expanded code get indented correctly as part
of the macro argument.
Add configuration to specify macros.
Macros will be expanded, and the code will be parsed and annotated
in the expanded state. In a second step, the formatting decisions
in the annotated expanded code will be reconstructed onto the
original unexpanded macro call.
Eventually, this will allow to remove special-case code for
various macro options we accumulated over the years in favor of
one principled mechanism.

MacroUnexpander applies the structural formatting of expanded lines into
UnwrappedLines to the corresponding unexpanded macro calls, resulting in
UnwrappedLines for the macro calls the user typed.

Some files still contained the old University of Illinois Open Source
Licence header. This patch replaces that with the Apache 2 with LLVM
Exception licence.

Summary:
The MacroExpander allows to expand simple (non-resursive) macro
definitions from a macro identifier token and macro arguments. It
annotates the tokens with a newly introduced MacroContext that keeps
track of the role a token played in expanding the macro in order to
be able to reconstruct the macro expansion from an expanded (formatted)
token stream.
Made Token explicitly copy-able to enable copying tokens from the parsed
macro definition.
