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).

fd7cb41920 gdb's shared-lib mapping code in solib.c has #ifdef dependencies on 
DT_MIPS_RLD_MAP being defined on mips targets with shared libs. Since
netbsd's gdb config.h defines HAVE_LINK_H, link.h is expected to
provide it. So #include <machine/elf_machdep.h> to make it so.

77a275d732 Change ld.so default behavior to RTLD_LOCAL, and make RTLD_LOCAL into a 
new flag bit.  Keep RTLD_GLOBAL as an actual flag bit so it won't be
re-used, or may be used for something later.  Mask the dlopen() mode bits
in ld.elf_so so a comparison against RTLD_NOW works.  (RTLD_{LOCAL,GLOBAL}
needs to be implemented for ld.elf_so.)

f00af7b07c Oops - when assembled with PIC, the jal gets expanded, so what used to be 
in the branch delay slot was no longer getting executed at the proper time.
This resulted in a corrupt ps_strings pointer and caused programs trying to
use ps_strings to fail.

5e0e8cec39 More table-driven changes for different toolchains: 
* new bsd.own.mk variable OBJECT_FMT with values "a.out" or "ELF".
  * use OBJECT_FMT in Makefile tests that depend on toolchain.
  * Add new bsd.own.mk variable NOSHLIB that, if set indicates a given
    port doesnt yet do shared libraries. Set on powerpc.
  * Document new feature-test variables in src/share/mk/bsd.README.
Tested on i386, mips, fakedup Alpha environment.

5fd7ce7066 These updates to the build allow building against include files 
and libs in the object tree, if you use a separate object tree,
while maintaining backward compatability with other build methods.
See the notes in src/share/mk/bsd.README for full details. Note
that the `make includes' target now only installs the include files
in the build directory (if you use one--otherwise they go in DESTDIR
just like before); `make install' will install include files in
DESTDIR.

RLTD_LAZY + 1 (for now), if it's not defined.  RTLD_NOW should be defined
in dlfcn.h, since some code (e.g. X11) wants it and assumes that it has
the value currently used by our RTLD_LAZY.

41fe218b25 First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf 
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.).  This runs, but it's
in serious need of cleaning and/or a fair bit of reworking.  See the README
file for more information, and a list of things to do.
