Small clenaup patches:
- safe_string.h - don't assume that __FUNCTION__ is available
- process.c - use new workaround from safe_string.h for the same
- util.c - Show how many bytes we smb_panic()ed trying to smb_xmalloc()
- gencache.c - Keep valgrind quiet by always null terminating.
- clistr.c - Add copyright
- srvstr.h - move srvstr_push into a .c file again, as a real function.
- srvstr.c - revive, with 'safe' checked srvstr_push
- loadparm.c - set a default for the display charset.
- connection.c - use safe_strcpy()
