466fa2adbf sha1: don't clean local variable i on exit
In this place value of variable i is constant and predictable. No point
to clean it. Furthermore, since the value is not used after assignment,
compiler will optimize and remove the assignment.

This patch fixes a warning from the clang static analyzer.

284e8f4421 tls/openssl: check return code
Check return code of SSL_CTX_set_default_verify_paths() and fail TLS on
an error. However, ignore the error when XMPP_CONN_FLAG_TRUST_TLS is
set.

cbe6701c14 Add xmpp_stanza_get_child_by_name_and_ns()
I think it's fairly common in the XMPP world to actually want a stanza
by it's NS but also want a certain name.

For example this was needed in Profanity:

6f075bfc71 resolver: fix gcc 9.2.0 warning
message_name_get() adds "." to the tail and it leads to:
    strncpy(&dest, ".", 1);
gcc 9.2.0 generates a warning, because string is truncated without
copying trailing '\0'. Replace strncpy() with memcpy() to fix the
warning.

18b67d6eaf tls/openssl: add LibreSSL support
OpenSSL and LibreSSL versions are incompatible. Moreover, LibreSSL
always define OPENSSL_VERSION_NUMBER as 0x20000000L. Instead of checking
for LibreSSL everywhere explicitly, redefine OPENSSL_VERSION_NUMBER.

886f45584c Fix bug with xmpp chat not connecting
The facebook suddenly stopped connecting on my dev machine. I still cannot
explain what caused this change in behaviour, but I was finally able to
diagnose and fix the problem.

Chat was not connecting due to an error in tls_start. The windows function
InitializeSecurityContext was returning a SEC_E_INCOMPLETE_MESSAGE status
which was being treated as an error. However, the documentation states
that this is not an error. This status simply indicates that more data
needs to be read. This commit does precisely that -- when
SEC_E_INCOMPLETE_MESSAGE we read more data from the socket and call
InitializeSecurityContext again.

2bf5cc0e41 auth: disable PLAIN when other mechanisms are supported
PLAIN mechanism sends password in BASE64 encoding which everyone can
read. As result, debug logs expose password and users often don't remove
it when post the logs in the Internet.

Usually, both a secure mechanism and PLAIN are used in the scenario when
username or password is incorrect. PLAIN fails in this scenario anyway.

a13ba65cfb Don't pass NULL to strcmp()
There are places where code relies on well-formed stanzas and expects
that ns attribute is always present. Check whether ns NULL or not before
passing it to strcmp().

0e6b0ef84d Only require session if it is not optional
RFC6121 removes the precondition of establishing a session before a client
may exchange XML stanzas on an XMPP network.

This PR allows libstrophe to not request session where it is indicated
as optional by the server, saving a round trip.
