Log message:
Fix private key encoding in i2d_ECPrivateKey()
The private key is a random integer between 1 and order - 1. As such it
requires at most as many bytes as the order to encode. SEC 1, Section C.4
is very explicit about padding it to this length:
The component privateKey is the private key defined to be the octet
string of length [ceil(log_2 n/8)] (where n is the order of the curve)
obtained from the unsigned integer via the encoding of Section 2.3.7.
Fix this by generalizing a similar fix for field elements.
