nx-X11/programs/Xserver/hw/nxagent/Render.c: use macros obtaining values from _XPrivDisplay instead of the other Display structure directly.

Fixes: ArcticaProject/nx-libs#512

It's unclear to me why (Display*)(dpy)->bitmap_pad and
(_XPrivDisplay)(dpy)->bitmap_pad produce different results.

Technically, Display is referencing the _XDisplay/Display structure
defined in Xlibint.h, while _XPrivDisplay is a typedef'd pointer to the
(anonymous) structure defined in Xlib.h, since we're not defining the
XLIB_ILLEGAL_ACCESS macro. The weird part is that both should be equal
when it comes to its bitmap_pad, byte_order and bitmap_bit_order
members.

Mesa.patches: Add 5001_nasty-typo-fixes.patch. Fix some nasty typos in Mesa's code ending up in the nxagent binary.

nx-X11/programs/Xserver/Render.c: Re-introduce nxagentGlyphsCleanup() from libNX_Xrender's formerly removed XRenderGlyphsCleanup().

Fixes ArcticaProject/nx-libs#500

 This change improves the situation in nxagent for the following
 issue:

 ```
 "XRenderCompositeTrapezoids builds RenderTrapezoids requests to composite the
 specified list of trapezoids to dst.  XRenderCompositeTrapezoids will split
 the list of trapezoids to build requests no larger than the maximum request
 size supported by the server.  This can create rendering artifacts as the
 precompositing done by RenderTrapezoids when a maskFormat is specified
 cannot span multiple requests."
 ```

 Fixes ArcticaProject/nx-libs#336.

This way one can easily pass options to nxagent run as Xnest
replacement without having to create a temporary options file. Please
note that it is not of much use for normal sessions. Options passed
like this cannot be changed after startup so a reconnect may not work
as expected.

Do not use global variables where it is not necessary.

Report Xlib-side window IDs to session.log in machine readable form. This feature can be enabled by the cmdline options -reportwids and -reportprivatewids.

Mesa.patches: Disable 4001_Fix-non-working-GLX-in-64bit-Xorg-7.0.patch. It patches a file, we don't build and that we remove in roll-tarball.sh.

 In nxagent sessions, all X11 clients have a representation of their NX
 session-side window object on the real X-Server side.

 The window object gets stored in the new NX_REAL_WINDOW window property
 immediately after window creation. This mapping is created in
 nxagentCreateWindow().

 On session resumption, the client side window IDs normally change. Thus,
 during session resumption, all NX_REAL_WINDOW properties require being
 updated. This happens in nxagentReconnectWindow().

 While a session is suspended, the NX_REAL_WINDOW property does not
 exist. It gets removed during nxagentDisconnectWindow().

hw/nxagnet/Atoms.c: In DEBUG mode, we need validateString() which is not statically defined in Utils.h. Thus including it for DEBUG builds.

Fix FTBFS on Linux based HP-PARisc 32-bit systems. Thanks to John Paul Adrian Glaubitz from FU Berlin for providing access to a corresponding porters' machine.

 This partially reverts nx-libs commit f6dcf2fe. The 'hpux' stuff stays
 out, the __hppa__ gets re-introduced.

    dix: Fix image byte order on big endian hardware

    Make sure X_BIG_ENDIAN/X_LITTLE_ENDIAN are defined before actually using
    them.

    Otherwise, image byte order could be wrong on big endian hardware even
    though endianess detection is correct.

    dix: Remove arch awareness from servermd.h (v2)

    At this point we have no architectures where image byte order is
    different from bitmap bit order, or where either of those two are not
    also the native word endianness.  Hooray, one more place where we don't
    have to worry about enabling new CPU architectures.

    v2: Rebase to master to handle the addition of ppc64le, arc, and xtensa,
    and use autoconf's endianness detection instead of gcc predefines.
