* Beginnings of SOM shared library support. Breakpoints and

	single frame backtracing within the library only.  Only works when
	using the HPUX 9 dynamic linker.  More functionality to be added
	soon.

	* somsolib.c, somsolib.h: New files.
	* Makefile.in (HFILES_NO_SRCDIR): Add somsolib.h
	(ALLDEPFILES): Add somsolib.c.
	(somsolib.o): Add some dependencies.
	* mpw-make.in (HFILES_NO_SRCDIR): Add somsolib.h
	(ALLDEPFILES): Add somsolib.c.
	(somsolib.o): Add some dependencies.
	* somread.c (som_symtab_read): Accept multiple section offsets.
	All callers changed.  Adjust all text symbols with the first
	section offset.
	* symfile.c (find_lowest_section): Enable this function.  Add some
	tie-breaking logic when sections have the same vma.
	(syms_from_objfile): Use find_lowest_section rather than looking
	for ".text" by name.  Relax warning to only warn if the lowest
	section is not a code section.
	* config/pa/{hppabsd.mh, hppahpux.mh} (NATDEPFILES): Add somsolib.o
	* config/pa/{nm-hppab.h, nm-hppah.h}: Include somsolib.h.
