[Xcb] [PATCH v2] expose 64-bit sequence numbers for XLib

[chris at demorecorder.com]

Hi Olivier,

Thank you for the ABI/API test with libxcb and constant xcb/proto.

However we'd need to do another test because
the primary risk for ABI/API issues are the changes in xcb-proto.

(As Uli has mentioned, we should not separate the releases for xcb/proto and xcb/libxcb.
And I agree with him.)

Therefore I suggest to repeat the ABI/API test with comparing the following:
* last official release of xcb/proto and xcb/libxcb
* compared with git - heads of xcb/proto and xcb/libxcb

We can ignore the ABI/API issues for the xinput-extension because
it was not officially supported in the last release. It was not built by default.

Some things to do, too:
* We should enable the xinput extension in the new release.

* Also, we should include Ulis send_fds patch.

* Check for any other pending patches that fix critical stuff.

* Do some testing with real applications and/or beta-test period.

Cheers,

Chris
