(solib_add): Rewritten: compare the inferior's current list of
shared objects with GDB's list, and do the required loads and
unloads.

to walk the list of shared libraries: call solib_add, and then
walk the list at so_list_head normally.

used.
* solib.c (SOLIB_EXTRACT_ADDRESS): New macro to extract addresses
from solib structures. Use it throughout solib.c, get rid of all
