Closes #116.

Generates a number coprime to 2, 3, 5, 7, 11.

Speed:
Trial div (add) : trial div (retry) : coprime
1 : 0.42 : 0.84

~2% speed improvement on trial division.

Possibly some reduction in bias, but no speed gains.

Make sure there is an extra 4 bytes for server done message when
NETSCAPE_HANG_BUG is defined.

While the -help message references this option, the man page
doesn't mention the -no_ecdhe option.
