Minor tidyings:

Browse Source 
search_all_symtabs: look for data symbols also in .sbss and .rodata
sections.

VG_(seginfo_sect_kind): identify addresses in .sbss sections.

VG_(pp_SectKind): handle missing case Vg_SectGOTPLT

search_all_loctabs, VG_(get_objname), VG_(find_seginfo): augment tests
"di->text_present" with "&& di->text_size > 0" (probably not
necessary, but is clearer, and more consistent in that most places
that look at DebugInfo.text_{size,avma} first perform both of those
tests).
