This only covers the ones in the pre-written code. There are many more
suggested in the generated code, which will require changing the generator
and will thus be handled separately.

Nothing was defining __solaris__ on Solaris in current build setup, and
it's not needed on Solaris 10 (released 2005) and later, which has
stdint.h. (Solaris 2.6 - 9 had inttypes.h, but no stdint.h.)

The UTF-8 quotes can appear in man pages etc as well, not only C code.
For example, in xcb_composite_redirect_subwindows.3:
xcb_composite_redirect_subwindows - Redirect all current and future
children of ‘window’
Note that window is quoted by a pair of UTF-8 single quotes.

Some people apparently use non-utf8 locales and this caused errors when
xcb-proto started using some "fancy" quote marks. Fix this by always
using utf8 encoding.

Merge request !30 broke compilation on Windows by introducing unbalanced
curly braces. This change restores the previous behavior on Windows:
only TCP is supported.
This updates the included xcb-proto to the newly required 1.16.
As explained in issue #70, this is a quick workaround, not the
long-term fix for this problem.

If DISPLAY starts with / or unix:, do not check for anything but a full
filesystem socket path. In particular, abstract AF_UNIX sockets and TCP
sockets will not be used in this case. Also be stricter about parsing
the screen part of /path.screen displays, and bail out after all stat()
errors other than ENOENT.

When combined with xorg/lib/libxtrans!7, this allows CVE-2020-25697 to
be mitigated by placing the AF_UNIX socket in a secure directory on the
filesystem.
This enables HAVE_LAUNCHD unconditionally and deletes the configure
switch.

If the function implementing xcb_connect is called directly with a
custom xcb_auth_info_t then checking that the screen in $DISPLAY
is valid is skipped.

On Solaris 10 and later, the pthread functions are directly in libc,
and libpthread only has metadata to redirect calls from it to the
libc functions.
On Solaris 9 and older (no longer supported), libc contained its own
thread stubs that libpthread then overrode.

This tutorial example only handles XCB_EXPOSURE and XCB_KEY_RELEASE
events and ignores everything else. Thus, there is no point in asking
for more kinds of events.
A while ago, I ported this tutorial to x11rb [1]. Recently, I received a
pull request [2] removing these unnecessary event masks. This commit is
thus only partially by me and the 'issue' was originally found by the
author of [2].

This fixes https://gitlab.freedesktop.org/xorg/lib/libxcb/-/issues/53
The issue was that libxcb expected to get a reply based on the request_expected
variable, but a reply would never arrive because the request was never actually
written. To resolve this, a separate request_expected_written variable is
added.
The c->in request counters are uint64_t, and can realistically go over
2**32 over a lifetime of a client. The c->in->replies map however uses
unsigned int keys and the passed request numbers are silently truncated.
I haven't analyzed in depth what happens what it wraps around but it's
probably nothing good.
The only user of the xcb_list.c map code is c->in->replies, so just
change it to use uint64_t keys.

The reason strings returned by the server don't all include a newline,
so make sure we add one to avoid confusing clients. Xlib used to do
this before it delegated that work to libxcb.

Using get_expr_fields() is only needed in case we are doing things that
can span multiple types easily, e.g. when deciding what data to pass via
function parameters and so on.
In _c_serialize_helper_list_field() we are building function body, so
acquiring field names via get_expr_field_names() is enough.
