Andrew Zaborowski 9ceca7a521 ie: Parse GTK and IGTK subelements in FTE 
Parse the contents of the GTK and IGTK subelements in an FT IE instead
of working with buffers containing the whole subelement.  Some more
validation of the subelement contents.  Drop support for GTK / IGTK when
building the FTE (unused).

Andrew Zaborowski 955c88a64a ie: Consistently set group_management_cipher 
RSNE_ADVANCE may return and if it is before the assignment of
info.group_management_cipher, that assignment will be dependent on where
the RSNE ends.

Andrew Zaborowski 316752c5e4 ie: Error in tlv_iter_next if no space to length byte 
When parsing the EAPoL-Key key data field we don't strip the 0xdd /
0x00 padding from the decrypted data so there may be trailing padding
after the IE sequence and valgrind will report an invalid read of the
length byte.  Same thing may happen if we're sent garbage.

Denis Kenzior 29a89d2a8b ie: There can be only one group_cipher 
So the use of & operation is unneeded.  A more correct way is to use the
equals operator.

Jukka Rissanen 458ac1aba4 ie: Simple informational element parser 
The parsing API goes through the byte stream and parses the
TLV (Type, Length and Value) values and avoids data copying.
