Needs more sophisticated features to actually test stuff correctly.

DO NOT USE!

The default function we use (if a thread name is not specified
explicitly) is pthread_self(). This function returns a number that is
guaranteed to be unique for each thread within a process, but this
assertion doesn't hold globally. Hence only using the thread ID is
ambiguous when logging from multiple processes.

Prevents race conditions caused by signal handlers while flushing out
our log queue.

This has one drawback: after flushing log data to its underlying output,
a new NXLogStamp object MUST be written to the NXLog object in order to
create a new entry within the stack.

This can be changed if necessary. For now I'd like to keep it as-is.

nxcomp/{configure.ac,Log.cpp}: implement configure-time std::put_time check and use macro value in Log.cpp.

This is to ensure the log output is the same as previous releases,
which didn't have INFO defined by default.

Features:
	* Works without ifdefs
	* Configurable with commandline arguments
	* Log level configurable per file
	* Thread safe

nx{comp{,shad},proxy}: add configure flag --enable-cxx11 to enable and setup optional C++11 support.

Use AX_CXX_COMPILE_STDCXX(_11) from autotools archive.

Note: should only be used in tandem. Make sure that each component
either uses the C++11 ABI or none uses it. Mixing and matching libraries
and binaries with different C++ ABIs might lead to weird errors.

README.md: add short Windows section and mention that using Cygwin tools is imperative when working with the git repository.

Hopefully just a temporary workaround until
https://bugzilla.redhat.com/show_bug.cgi?id=1489712 /
https://bugs.centos.org/view.php?id=13779 are resolved.

Commit 5f1eb0dc introduced a regression
that made the use of the multimedia port mandatory.

Fixes ArcticaProject/nx-libs#525

These are already cleaned up by the top-level Makefile.

nxcomp/src/Loop.cpp: Reduce control->TokenSize slightly again in order to fix fragmentation of packages when on VPN (or otherwise encapsulated) connections.

 Fixes ArcticaProject/nx-libs#506.

Fix nxagent argument parsing logic

This makes it so that slave=1 and media=1 work again as they should.

The changes introduced earlier resulted in the unintentional requirement
to specify the actual port number, breaking backwards compatibility.

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.

Fixes: ArcticaProject/nx-libs#507

nxcomp/src/{Loop,Proxy}.cpp: On Debian/kFreeBSD (and other *BSD variants) the sockaddr_un.sun_path property is 104 chars long, not 108. Hard-coding Unix domain sockets in nxcomp the string length 104.
