Consolidate partial symtab dependency reading

Browse Source 
Most of the symbol readers have code to iterate over a partial symtabs
dependencies, expanding each one and optionally printing a message.
Now that the "second-stage" psymtab expansion is available as a
method, these implementations can all be merged.

This patch also changes a couple more warnings into assertions.
