nnposter b1d39d00d4 Skip TLS/SSL retries when SSL_OP_NO_SSLv2 is a no-op 
OpenSSL option SSL_OP_NO_SSLv2 was retired with version 1.1.0
When the initial SSL handshake fails, nmap performs several additional retries
with option SSL_OP_NO_SSLv2 enabled. Since the option is ignored since OpenSSL
version 1.1.0 then the retries are largely pointless and sometimes even DoS-ing
targets.
Closes #1873, fixes #1488, closes #1489

Using Nmap

Nmap has a lot of features, but getting started is as easy as running nmap scanme.nmap.org. Running nmap without any parameters will give a helpful list of the most common options, which are discussed in depth in the man page. Users who prefer a graphical interface can use the included Zenmap front-end.
