nxcompshad/X11/include/Xdamage_nxcompshad.h: Update FIXME statement. Work-around needs to persist until libX11 from X.Org gets used by nxagent.

pointer typedef in Xdefs.h: Define pointer type for building against older Xlib versions that still expect the pointer type to exist (e.g. Ubuntu <= 14.04, Debian <= 7.0).

Attributes GH PR #61: https://github.com/ArcticaProject/nx-libs/pull/61

 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.

Xinerama symlinking: Create / remove folder containing Xinerama sylinks on installation/upgrade and removal.

Various fixes for pkgconfig file creation.

This reverts commit b77b26f4.

Should be a weak dependency, but RPM doesn't support that too well yet.

Cherry-picked from 3.5.0.x branch.

Cherry-picked from 3.5.0.x branch.

 As the system a tarball gets extracted on may potentially be unable
 to handle symlinks, we ship symlinks as files in the rolled tarball.

 By transforming symlinks into real files, we also assure that all
 VERSION files/symlinks get shipped in the tarballs.

 Fixes ArcticaProject/nx-libs#27

xorg-server does not follow the convention of using 2 dashes,
and apparently nx-libs doesn't either.

Note that --help does produce the help output. However, it
produces this additional output after it:

Error: NX transport initialization failed.

Therefore, we should instruct users to call -help instead.
