9682d2c2c9 FS-11730 Add support for DTLSv1.2 and make default 
Needed in Chrome version >= 74 as Chrome dropped support for v1.0:
https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/discuss-webrtc/yr6gbAgWsKo/9X5vQb8kGAAJ

Using old v1.0 DTLS if 1.2 is not available or legacy DTLS
wanted explicitly. To request old DTLS set variable

	<action application="set" data="legacyDTLS=1"/>

Note: requires openssl 1.0.2 or later for DTLS v1.2 support

25682d619c FS-11201 Fix 'rtt_valid = 0;' was incorrectly placed rendering whole RTT thing void. 
+ don't shoot in a leg and keep 'rtt_now' value correct (even if we clear it few lines after), because after some time it could be changed.

2dcfc27963 FS-11360 Fix FS degradation over time in DTLS layer (especially if outdoing packets rate higher that incoming) 
When we handle DTLS layer in do_dtls() and there are no incoming packets yet - we still call BIO_write() with NULL buffer and it is an error and BIO_write() will stuck for a long time in libssl/libcrypto error subsystem.
(that also possibly relates to fact that libssl/libcrypto init/deinit/error-handling is broken in general in FS, however that is another big issue)

6cd17fd556 FS-11052: Allow alias for crypto suites 
For outgoing calls send AES crypto in offer using corrected names
for keys of length 192 and 256, i.e. names containing _192_CM_
and _256_CM_ instead of _CM_192_ and CM_256_. For incoming calls
accept both naming conventions, decaying to same entry in SUITES.

+ fix after SRTP failed for 256 keys:

Tests showed loop removing '=' from keys in switch_core_media_build_crypto

 1190     if (!switch_channel_var_true(channel, "rtp_pad_srtp_keys")) {
 1191         p = strrchr((char *) b64_key, '=');
 1192
 1193         while (p && *p && *p == '=') {
 1194             *p-- = '\0';
 1195         }
 1196     }

shouldn't be executed for AES_CM_256_HMAC_SHA1_32 and AES_CM_256_HMAC_SHA1_80
keys and it is meaningless for AES_CM_128_HMAC_SHA1_32 AES_CM_128_HMAC_SHA1_80
keys. Tested calling from Bria.

Introduced switch_channel_var_false and changed this to:
	if (switch_channel_var_false(channel, "rtp_pad_srtp_keys"))
to enter the loop if var is set to false (and not if it is _not_ set).

bad RTT values).
