le: handle BT 5.0 long packets

As of Bluetooth 5, LE packets can be up to 255 octets long. Do not
truncate when capturing such long packets. Note that there is still an
assert lying around in the PcapNG code, waiting to be tripped.

pcapng: Eliminate/Document some magic numbers.

* The magic number of 36 used when calculating the block_length
represents the size of the 'Enhanced Packet Block' in pcapng (excluding
the data packet itself). Replace the magic number with a macro. See
http://www.winpcap.org/ntar/draft/PCAP-DumpFileFormat.html#sectionepb

* The magic number of 9 added to the caplen represents the extra bytes
of a BLE link layer packet outside of the PDU payload. Added a comment
to identify what those extra 9 bytes represent.

Fix buffer overflow in assemble_pcapng_le_packet().

The pcapng_le_packet structure did not allocate enough storage to
contain the OPTIONS and BLOCK_TOTAL_LENGTH fields at the end of the
pcapng enhanced block structure (see
http://www.winpcap.org/ntar/draft/PCAP-DumpFileFormat.html#sectionepb).

* Added fields to pcapng_le_packet structure for options and length
along with two bytes of padding to allow for 32 bit alignment of
options and length fields.
* Added assert() to catch cases of potential buffer overflow.

This fixes the following bug report in ubertooth project:
