[Bug runtime/10599] New: Always print module/map names for kernel/executable addresses

- Reply-to: sourceware-bugzilla at sourceware dot org
When the context tapset modname, [u]symname, [u]symdata or the backtrace
addresses mapped to symbol names (all this translates to _stp_symbol_print,
_stp_usymbol_print or _stp_symbol_snprint in runtime/syms.c) we only print the
module/library name associated with the address if we are currently tracking it.
Which means, we only print the module/library map name if we already have it in
our _stp_modules list.
Better vma tracking (bug #10228) means we get events for each loaded kernel
module and each mmap event (plus associated backing [shared library] file). We
should build a table of this so we can easily add support for at least printing
<module/map-name>+offset from the sym.c symbol_print functions.
Also slightly related, to print <vdso>+offset, bug #10080.
