Corrected an extraction issue in which an error message about

"unexpected asymmetric device" is printed prematurely, as it
is inside a loop checking over all device entries compatible
with a device type.  Also:  Flagged an issue with the "label"
keyword in the "cifinput" section of a tech file.  The "label"
keyword cannot be used in conjunction with boolean operators.
It can only connect labels on a specific GDS type to one magic
type.  Unfortunately, because this was not flagged before as
an error or warning, the incorrect usage has crept into a lot
of tech files.  This uncovers an underlying issue that labels
must be allowed to automatically reconnect types, which is
undermined by the "no-reconnect-labels" cifinput option.  That
issue will be addressed in an upcoming commit.
