    [PATCH] os: XDMCP options like -query etc. should imply -listen tcp

    In X server 1.17, the default configuration is now -nolisten tcp.  In this
    configuration, XDMCP options don't work usefully, as the X server is not
    listening on the port for the display that it tells the display manager to
    connect to.

    os/xdmcp: Remove dead 'restart' code

    The X server used to wait for the user to hit a key or move the mouse
    before restarting the session after a keepalive failure. This,
    presumably, was to avoid having the X server continuously spew XDMCP
    protocol on the network while the XDM server was dead.

    Switching into this state was removed from the server some time before
    XFree86 4.3.99.16, so the remaining bits of code have been dead for
    over a decade, and no-one ever noticed.

    os/xdmcp: Just send XDMCP keepalive packets once every three minutes

    There was a complicated scheme to increase the time between keepalives
    from 3 minutes up to as much as 24 hours in an attempt to reduce
    network traffic from idle X terminals. X terminals receiving X
    traffic, or receiving user input would use the 3 minute value; X
    terminals without any network traffic would use a longer value.

    However, this was actually broken -- any activity in the X server,
    either client requests or user input, would end up resetting the
    keepalive timeout, so a user mashing on the keyboard would never
    discover that the XDMCP master had disappeared and have the session
    terminated, which was precisely the design goal of the XDMCP keepalive
    mechanism.

    Instead of attempting to fix this, accept the cost of a pair of XDMCP
    packets once every three minutes and just perform keepalives
    regularly.

    This will also make reworking the block and wakeup handler APIs to
    eliminate select masks easier.

 This has already been started while replacing copyright info in file
 headers and has now been completed with this commit.

Fixes ArcticaProject/nx-libs#105

 In the process of building nxagent against more and more system-wide installed
 X.org libraries, we come to the limit of including structs from this (bundled
 nx-X11) and that (system-wide X.Org) library.

 This commit introduces a clear namespace separation of headers provided by
 nx-X11 and headers provided by X.Org. This approach is only temporary as we
 want to drop all nx-X11 bundled libraries from nx-libs.

 However, for a while we need to make this separation clear and also ship
 some reduced fake X.Org headers that avoid pulling in libX* and libNX_X*
 symbols at the same time.

 This patch has been tested on Debian jessie and unstable and requires no
 overall testing on various distros and distro versions, as we finally will
 drop all libNX_X* libraries and build against X.org's client libs.

 For now, this hack eases our development / cleanup process.

 This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer'
 is used throughout the X server for other things, and having duplicate
 names generates compiler warnings.
