// Satoshi's original implementation used BN_bn2mpi() and BN_mpi2bn().
// MPI uses the most significant bit of the first byte as sign.
// Thus 0x1234560000 is compact (0x05123456)
// and 0xc0de000000 is compact (0x0600c0de)

// Bitcoin only uses this "compact" format for encoding difficulty
// targets, which are unsigned 256bit quantities. Thus, all the

* Variable-length integers: bytes are a MSB base-128 encoding of the number.
* The high bit in each byte signifies whether another digit follows. To make
* sure the encoding is one-to-one, one is subtracted from all but the last digit.
* Thus, the byte sequence a[] with length len, where all but the last byte
* has bit 128 set, encodes the number:
*
* (a[len-1] & 0x7F) + sum(i=1..len-1, 128^i*((a[len-i-1] & 0x7F)+1))
*
* Properties:
* * Very small (0-127: 1 byte, 128-16511: 2 bytes, 16512-2113663: 3 bytes)
* * Every integer has exactly one encoding
* * Encoding does not depend on size of original integer type
* * No redundancy: every (infinite) byte sequence corresponds to a list
* of encoded integers.
