- Potential NULL dereference in tsmf_ifman.c
- Check return value for our functions in tsmf_media.c and rdp.c
- Bad binary operator used in gcc.c
- Unreachable code in ntlm.c
- Bad free operation on SCOPE_LIST object in license.c
Made sure the list_*() API was used whenever possible, rather than relying on the internal implementation.
Added comments to the list.c file for documentation.
