2a05365bbb _rtld_unref_dag(): needed->obj might be null if the unreffed object has 
some unsatisfied references (most often when compiled without necessary
	-Wl,-R), so check for that instead of causing null-dereference;
	this way the code has a chance to cleanup after itself and report
	the error to caller

Thanks to Jason Thorpe for helping fix this!

5c5817ee4a When allocating the entire address space of an object, map an anonymous 
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.

The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.

This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

ld.elf_so there?
