small fixes for delay
...
firstly, test_cipher_on_target() will try at least 4 connections before
incurring the sleep, for aggressive rate limiter on server side it may be
too much, so sleep before every connection
secondly, because running external commands like sleep incurs a fork
penalty, we first check if it is necessary

fix EDH checking

make cipher selection simulation generic
...
it's relatively easy to make the cipher selection generic,
so that adding different clients is as easy as converting their
client hello cipher ordering to openssl cipher names

report cipher ordering in scanning stats, use it to simulate handshakes
...
since now we know if server honours client order or not, we can use it
to properly simulate handshakes for a given client, also report
the general stats of this server configuration variable

extend reporting of RC4-related stats

While preferring RC4 in TLS1.0 or SSL3 was recommended before,
it was always known that TLS1.1 and TLS1.2 were not vulnerable against
BEAST, so forcing RC4 there is a mistake. Report number of such servers.
