Add sanity checks to make sure the claimed block size is big enough to:

	1) contain the block length fields and block type field;

	2) contain that plus the fixed-length portion of the block;

	3) for blocks that have a variable-length portion other than the
	   options, contain that variable-length portion.

Fixes a crash we're seeing with a bad pcap-NG file in the Wireshark
menagerie (7799-lastPacketWithoutComment.pcapng - the last packet's
block length is 128, but it claims to have 98 bytes of packet data,
which requires a 132-byte block).

Clean up white space (use 8-space tabs).
