sample/fetch support for TLS extensions

[Alexey Elymanov]

I would like to propose a little patch, based on current ssl_capture
(ssl_sock.c) scheme.
Purpose is to be able to sample/fetch TLS extensions, it could be useful
for debugging or fingerprinting purposes (for example, cURL and Firefox
provide different sets of extensions in ClientHello message).

it provides two hooks, which should be enough for further Lua
processing/request forwarding/analysis: smp_fetch_ssl_fc_exts_bin,
smp_fetch_ssl_fc_exts_hex
