Also, we only enable expansion by default if pdfTeX can expand the fonts automatically.

\MT@config@file
\MT@get@config
The main configuration file will be loaded before processing the package options.
However, the config option must of course be evaluated beforehand. We also have
to define a no-op for the regular option processing later.

\MT@check@active@set
We have to make sure that font sets are active. If the user didn’t activate any, we
use those sets declared by \DeclareMicrotypeSetDefault (this is done at the end
of the preamble).
\def\MT@check@active@set#1{%
\MT@ifdefined@n@TF{MT@#1@setname}{%
\MT@info@nl{Using \@nameuse{MT@abbr@#1} set ‘\@nameuse{MT@#1@setname}’}%

\MT@glet@nn{MT@#1@setname}{MT@default@#1@set}%
\MT@info@nl{Using default \@nameuse{MT@abbr@#1} set ‘\@nameuse{MT@#1@setname}’}%
}{%
If no default font set has been declared in the main configuration file, we use the
(empty, non-existent) set ‘@’, and issue a warning.
