+ MINOR: threads: Make sure threads_sync_pipe is initialized before using it.
+
+ thread_want_sync() might be called before thread_sync_init() was called,
+ at least when reading the server state file, as apply_server_state() is called
+ before thread_sync_init(). So make sure the threads_sync_pipe was initialized
+ before writing to it, if it was not, there's no thread, so no need to sync
+ anything anyway, and if we don't check it we'll end up writing a 'S' on
+ stdin.
+
+ this only applies to 1.8.

+ BUG/MINOR: backend: check that the mux installed properly
+
+ The return value from conn_install_mux() was not checked, so if an
+ inconsistency happens in the code, or a memory allocation fails while
+ initializing the mux, we can crash while using an uninitialized mux.
+ In practice the code inconsistency does not really happen since we
+ cannot configure such a situation, except during development, but

+
+ This should be backported to 1.8 (the code is a bit different there,
+ there are two calls to conn_install_mux()).

+ MEDIUM: ssl: add support for ciphersuites option for TLSv1.3
+
+ OpenSSL released support for TLSv1.3. It also added a separate function
+ SSL_CTX_set_ciphersuites that is used to set the ciphers used in the
+ TLS 1.3 handshake. This change adds support for that new configuration
+ option by adding a ciphersuites configuration variable that works
+ essentially the same as the existing ciphers setting.
+
+ Note that it should likely be backported to 1.8 in order to ease usage
+ of the now released openssl-1.1.1.

+ BUG/MEDIUM: Cur/CumSslConns counters not threadsafe.
+
+ CurSslConns inc/dec operations are not threadsafe. The unsigned CurSslConns
+ counter can wrap to a negative value. So we could notice connection rejects
+ because of MaxSslConns limit artificially exceeded.
+
+ CumSslConns inc operation are also not threadsafe so we could miss
+ some connections and show inconsistenties values compared to CumConns.
+
+ This fix should be backported to v1.8.

+ MINOR: lua: all functions calling lua_yieldk() may return
+
+ There was a mistake when tagging functions which always use longjmp and
+ those which may use it in that all those supposed to call lua_yieldk()
+ may return without calling longjmp. Thus they must not use WILL_LJMP()
+ but MAY_LJMP(). It has zero impact on the code emitted as such, but
+ prevents other fixes from being properly implemented : this was the
+ cause of the previous failure with the __unreachable() calls.
+
+ This may be backported to older versions. It may or may not apply
+ well depending on the context, though the change simply consists in
+ replacing "WILL_LJMP(hlua_yieldk" with "MAY_LJMP(hlua_yieldk", and
+ same with the single call to lua_yieldk() in hlua_yieldk().

+ BUILD: Makefile: speed up compiler options detection
+
+ Commits b78016649 and d3a7f4035 brought the ability to detect the build
+ options and warnings that the compiler supports. However, they're detected
+ using "$(CC) -c", which is 50% slower than "$(CC) -E" for the same result,
+ just because it starts the assembler at the end. Given that we're starting
+ to check for a number of warnings, this detection alone starts to become
+ visible, taking a bit more than 300 ms on the build time. Let's switch to
+ -E instead to shrink this incompressible time by roughly 100 ms.
