Remove non-functional code for unloading loadable modules.

Browse Source 
The code for unloading a library has been commented-out for over 12
years, ever since commit 602a9ef5a7, and we're
no closer to supporting it now than we were back then.

Optionally, a dynamically loaded file can contain an initialization
function. If the file includes a function named
<function>_PG_init</function>, that function will be called immediately after
loading the file. The function receives no parameters and should
return void. If the file includes a function named
<function>_PG_fini</function>, that function will be called immediately before
unloading the file. Likewise, the function receives no parameters and

during an unload of the file, not during process termination.
(Presently, unloads are disabled and will never occur, but this may
change in the future.)
