Merge from head to stable/7:

r189771:
Implement new way of branding ELF binaries by looking to a
".note.ABI-tag" section.

The search order of a brand is changed, now first of all the
".note.ABI-tag" is looked through.

Move code which fetch osreldate for ELF binary to check_note() handler.

r189919:
Use the properly sized types for ELF object header and program headers.
This fixes osrel fetching from the FreeBSD branding note for the 64bit
platforms (bug introduced by r189771).

r190264:
Fix several issues with parsing the notes for ELF objects.

Badly formed ELF note may cause the caclulated pointer to the next note
to point both after the note region, that was checked in the code, but
also to point before the region, that was not checked [1]. Remember the
first note location in note0 and leap out if the note is not between
note0 and note_end.

In the similar way, badly formed note may cause infinite loop by
pointing next note into the same or previous note. Guard against this
by
limiting amount of loop iterations by arbitrary choosen big number.

For clarity, check the calculated note alignment in each iteration.
