Add more methods to gdb.Progspace

Browse Source 
There are a number of global functions in the gdb Python module which
really should be methods on Progspace.  This patch adds new methods to
Progspace and then redefines these globals in terms of these new
methods.

This version has been rebased on the related changes that Simon
recently put in.

Built and regtested on x86-64 Fedora 28.
