Make psymbols and psymtabs independent of the program space 

This patch finally makes partial symbols and partial symtabs
independent of the program space.

Specifically:

It changes add_psymbol_to_list to accept a section index, and changes
the psymbol readers to pass this.  At the same time it removes the
code to add the objfile's section offset to the psymbol.

It adds an objfile argument to the psymtab textlow and texthigh
accessors and changes some code to use the raw variants instead.

It removes the "relocate" method from struct quick_symbol_functions,
as it is no longer needed any more.

It changes partial_symbol::address so that the relevant offset is now
applied at the point of use.
