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.

xorg-server does not follow the convention of using 2 dashes.

Note that --help does produce the help output. However, it

Error: Aborting session with 'Unrecognized option: --help'.
Session: Aborting session at 'Sun Jun 28 01:35:35 2015'.
Session: Session aborted at 'Sun Jun 28 01:35:35 2015'.

It also causes a return code of 1 rather than 0.

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

COPYING: Replace content with GPL-2 license text, because that is the overall (i.e., strictest) license we have to deal with in nx-libs.

debian/roll-tarball.sh: Rename README.md to README.NX-Development before moving it into doc/ folder.

* bin/{nxagent,nxauth,x2goagent}
* etc/
* doc/nx-X11_vs_XOrg69_patches
* README.keystrokes"
* nx-libs.spec

debian/roll-tarball.sh: Allow patch files names having a dash next to the four digits (i.e., 1234-<patchname>.<suffix>).

 Due to C arithmetic conversion rules we must use an unsigned constant (or a
 cast) to perform the multiplication using unsigned arithmetic.

 Fixes ArcticaProject/nx-libs#55.
