Make host_address_to_string/gdb_print_host_address cast parameter to 'void *'

Fixes a set of errors like:

 ../../src/gdb/symfile-debug.c: In function ‘int debug_qf_map_symtabs_matching_filename(objfile*, const char*, const char*, int (*)(symtab*, void*), void*)’:
 ../../src/gdb/symfile-debug.c:137:39: error: invalid conversion from ‘int (*)(symtab*, void*)’ to ‘const void*’ [-fpermissive]
	host_address_to_string (callback),
					^

Note this has to work with data and function pointers.  In C++11 we
may perhaps do something a bit safer, but we're not there yet, and I
don't think it really matters.  For now just always do a simple
C-style cast in host_address_to_string itself.  No point in adding a
void * cast to each and every caller.
