+
+ Fix hang in xcb_request_check()
+
+ 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.

+
+ Avoid request counter truncation in replies map after 2**32 requests
+
+ 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.

+
+ In _c_serialize_helper_list_field() we are building function body, so

+Author: Peter Harris <pharris%opentext.com@localhost>

+
+ Fix writev emulation on Windows
+
+ There are at least two bugs in the previous implementation:
+
+ - If an early iovec is partially written, there can be a gap of missing
+ data (as a later iovec will be started before the early iovec is
+ completed).
+ - If a late iovec returns WSAEWOULDBLOCK, *vector and *count are not
+ updated, leading to a re-send of the entire request.
+
+ Move the *vector update into the send() loop to update piecemeal as
+ individual iovecs are sent.
+
+ Example program that demonstrates the issue (this program should run
+ forever after these bugs have been fixed):
+
+ #include <stdio.h>
+ #include <stdlib.h>
+ #include "xcb.h"
+
+ // Non-cryptographic random number generator from http://burtleburtle.net/bob/rand/smallprng.html
+ // because Microsoft's random number generators either have a too small RAND_MAX or are too slow
+ typedef struct ranctx { uint32_t a; uint32_t b; uint32_t c; uint32_t d; } ranctx;

+
+ Increment libtool version info for libxcb-dri3
+
+ Somewhat belatedly given the last update was in xcb-proto 1.13 in 2017...
+
+ Quoting @smcv from https://bugs.debian.org/921069:
+ >>>
+ libxcb-dri3 version 1.13 appears to have added new symbols without increasing
+ the minor ABI version in its -version-info. This will break anything that
+ compares libraries by their version info to decide which one is newer.
+
+ The Steam Runtime uses libraries' major/minor/micro ABI version info (in this
+ case 0.0.0) to decide whether to use the system copy of a library or the copy
+ in the Steam Runtime, depending on which one is newer (#921026). We can
+ work around this by adding a versioned dependency on libxcb-dri3-0 and
+ deleting the copy from the Steam Runtime, but this isn't a particularly
+ scalable solution.
