Add TLS padding extension to SSL_OP_ALL so it is used with other
"bugs" options and can be turned off.

This replaces SSL_OP_SSLREF2_REUSE_CERT_TYPE_BUG which is an ancient
option referring to SSLv2 and SSLREF.

armcap.c is shared between 32- and 64-bit builds and features link-time
detection of getauxval.

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.

This patch fixes this omission.

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