Nicks and blurbs don't have any practical use for gio/gobject libraries.
Leaving tests untouched since this features is still used by other libraries.
Closes#2991

certain pattern in their existing non-machine-readable header comment.

Since
https://gitlab.gnome.org/GNOME/glib-networking/-/merge_requests/173,
there is now a really surprising implication to using a non-default
GTlsDatabase: your database could do nothing at all other than wrap the
default database, which you would expect to result in no behavior
changes, but in fact it causes fewer security checks to be performed
during certificate verification. This is because certificate
verification moved from GTlsDatabase to GTlsConnection, allowing for
more security checks to be performed. But if using a non-default
GTlsDatabase, we have to fall back to letting GTlsDatabase to the
verification, as before.
This is the best we can do. It's not a regression for applications,
because it means applications get the previous pre-2.72 behavior. But it
does mean that new security checks added in 2.72 are not applied, which
is unfortunate, so we should warn developers about this.
Once upon a time, we tried to return all possible certificate errors,
but it never actually worked reliably and nowadays we have given up.
This needs to be documented because a reasonable developer would not
expect it.
Because mistakes could be security-critical, I decided to copy the same
warning in several different places rather than relying only on
cross-referencese.
This adds g_tls_connection_get_protocol_version(),
g_tls_connection_get_ciphersuite_name(), and DTLS variants. This will
allow populating TLS connection information in the WebKit web inspector.
This is WIP because we found it's not quite possibly to implement
correctly with GnuTLS. See glib-networking!151.
* Add g_tls_connection_get_channel_binding_data API call
* Add g_dtls_connection_get_channel_binding_data API call
* Add get_binding_data method to GTlsConnection class
* Add get_binding_data method to GDtlsConnection interface
* Add GTlsChannelBindingType enum with tls-unique and
tls-server-end-point types
* Add GTlsChannelBindingError enum and G_TLS_CHANNEL_BINDING_ERROR
quark
* Add new API calls to documentation reference gio-sections-common
In glib-networking#127, it was reported that we don't properly implement
the documented behavior of these properties. However, we cannot fix it
because libsoup relies on the implemented behavior, and it's hard to
change that without cascading breakage. The practical solution is to
adjust our documentation to match reality. There should be no downsides
to this, and compat risk of changing the documentation is much smaller
than risk of changing the implementation, so I think this is the best we
can make of an unfortunate situation. See glib-networking#127 for full
discussion and glib-networking#129 for the regression when we attempted
to match the documented behavior.
Previously, the documentation indicated that it was possible to call
g_tls_connection_handshake() after an initial handshake to trigger a
rehandshake, but only if TLS 1.2 or older is in use. However, there is
no documented way to ensure TLS 1.2 gets used. Nowadays, TLS 1.3 is used
by default.
I'm removing support for rehandshaking from glib-networking, as part of
a large refactoring where keeping rehandshakes would have entailed
significant additional complexity. So let's update the documentation to
indicate this is no longer ever supported. Applications should not
notice any difference.
Also, sync some previous handshake and rehandshake changes from
GTlsConnection to GDtlsConnection that were missed by mistake. I
try to remember to always update GDtlsConnection when touching
GTlsConnection documentation, but it's easy to forget.
Sadly, I forgot to update the documentation of
g_dtls_connection_handshake() last time I touched
g_tls_connection_handshake().
Let's also drop mention of STARTTLS, since that would use normal TLS,
not DTLS.
Using the generic marshaller has drawbacks beyond performance. One such
drawback is that it breaks the stack unwinding from the Linux kernel due
to having unsufficient data to walk past ffi_call_unixt64. That means that
performance profiling by application developers looks grouped among
seemingly unrelated code paths.
While we can't fix the kernel unwinding here, we can provide proper
c_marshallers and va_marshallers for objects within Gio so that
performance profiling of applications is more reliable.

These have all been documented as deprecated for a long time, but we’ve
never had a way to programmatically mark them as deprecated. Do that
now.
This is based on the list of deprecations from the reverted commit
80fcb1bc2.

Fixes: #638
Allowing unsafe rehandshakes used to be required for web compatibility,
but this is no longer a concern in 2018. So there should no longer be
compatibility benefits to calling this function. All it does is make
your TLS connection insecure.
Also, rehandshaking no longer exists at all in TLS 1.3.
At some point (maybe soon!) glib-networking will begin ignoring the
rehandshake mode, so let's deprecate it now.
Let's entirely deprecate calling this function for rehandshaking. The
current documentation is OK, but guarantees defined behavior (to attempt
a rehandshake) when TLS 1.2 is in use. But there's no way to force TLS
1.2, and also no way to check which version of TLS is in use. I really
should have deprecated use of this function for rehandshaking entirely
last time I updated it.
Fortunately, there should be no compatibility risk for existing code,
because rehandshaking has no visible effects at the API level.
This will fix a few broken links in the documentation, and shut up a
load of gtk-doc warnings (but certainly not all of them).

It's unnecessary, and only adds visual noise; we have been fairly
inconsistent in the past, but the semi-colon-less version clearly
dominates in the code base.

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
Add a new GDtlsConnection interface, plus derived GDtlsClientConnection
and GDtlsServerConnection interfaces, for implementing Datagram TLS
support in glib-networking.
A GDtlsConnection is a GDatagramBased, so may be used as a normal
datagram socket, wrapping all datagrams from a base GDatagramBased in
DTLS segments.
Test cases are included in the implementation in glib-networking.
