Improve handling of dlopen(RTLD_TRACE) aka ldd, of a library that is already loaded: * add a 'trace' argument to _dl_show_objects() and exit the walk-the-objects loop if you hit that traced object * in dlopen(), pass the trace object to _dl_show_objects() * also, invoke _dl_show_objects() + exit if the object was already opened * pass NULL to _dl_show_objects() for all the other calls * oh hey, _dl_tracelib is now superfluous: _dl_show_objects() should do the walk-the-objects loop only if trace is not NULL.

Use a better algorithm for calculating the grpsym library order. The existing code did a full recursive walk for O(horrible). Instead, keep a single list of nodes plus the index of the first node whose children haven't been scanned; lookup until that index catches the end, appending the unscanned children of the node at the index. This also makes the grpsym list order match that calculated by FreeBSD and glibc in dependency trees with inconsistent ordering of dependent libs. To make this easier and more cache friendly, convert grpsym_list to a vector: the size is bounded by the number of objects currently loaded. Other, related fixes: * increment the grpsym generation number _after_ pushing the loading object onto its grpsym list, to avoid double counting it * increment the grpsym generation number when building the grpsym list for an already loaded object that's being dlopen()ed, to avoid incomplete grpsym lists * use a more accurate test of whether an object already has a grpsym list Prompted by a diff from Nathanael Rensen (nathanael (at) list.polymorpheus.com) that pointed to _dl_cache_grpsym_list() as a performance bottleneck. Much proding from robert@, sthen@, aja@, jca@ no problem reports after being in snaps ok mpi@

Simplify _dl_find_symbol(). Currently, it returns three values: - the symbol it found, returned via the second argument - the base offset of the the object it was found in, via the return value - optionally: the object it was found in, returned via the last argument Instead, return a struct with the symbol and object pointers and let the caller get the base offset from the object's obj_base member. On at least aarch64, amd64, mips64, powerpc, and sparc64, a two word struct like this is passed in registers. ok mpi@, kettenis@

Some cleanup in loader.c, initialize the symbol pointer with NULL, add a missing initialization of the sym pointer. Add some functionality which allows a program to open itself dlopen(NULL), so that it can then look up symbols in the executable itself. Note that the program can only access exported variables, either by exporting all variables with the ld option -E or externally referrenced. Fix bug in dlsym() where it would return failure when looking up symbols. It was testing the offset of the found symbol, not if the symbol was found.
