The existing implementation folds addr(deref(X)) => X only. This
change makes it also work the opposite way.

…x types

The current implementation translates '-EXPR' into
'ZERO_EXPR - EXPR'. It handles EXPR of floating-point types as a
special case for which ZERO_EXPR is -0.0. This change applies the
same approach to EXPR of complex types so that '-CMPLX_EXPR'
translates into '(-0.0-0.0i) - CMPLX_EXPR' instead of
'(0.0+0.0i) - CMPLX_EXPR'.

Signame() checks for HAVE_STRSIGNAL but the current
implementation never defines it. This change adds a
check for strsignal() existence to cmake rules.

Arrange for tests that call setMimeInit to fully restore the old values,
by clearing the sync.Once that controls initialization.

Once we've done that, call initMime in initMimeUnixTest because
otherwise the test types loaded there will be cleared by the call to
initMime that previously was not being done.
