891ea6512e Improvements in muxcover 
- Slightly under-estimate cost of decoder muxes
- Prefer larger muxes at tree root at same cost
- Don't double-count input cost for partial muxes
- Add debug log output

5e443a5d0d Fix two instances of integer-assignment to string. 
o In cover.cc, the int-result of mkstemps() was assigned to a string
  and silently interpreted as a single-character filename with a funny
  value. Fix with the intent: assign the filename.
o in libparse.cc, an int was assigned to a string, but depending on
  visible constructors, this is ambiguous. Explicitly cast this to
  a char.

aeeefc32d8 attrmap: extend -remove to allow removing attributes with any value. 
Currently, `-remove foo` would only remove an attribute `foo = ""`,
which doesn't work on an attribute like `src` that may have any
value. Extend `-remove` to handle both cases. `-remove foo=""` has
the old behavior, and `-remove foo` will remove the attribute with
whatever value it may have, which is still compatible with the old
behavior.
