Commit 3f7b3001 was incomplete: the
options parameter was not parsed as a string on reconnect. It was
always assumed to be a filename.

This change make the code more similar to upstream Xorg which helps
when merging in changes from later Xorg releases.

This has also been done in Xorg 7.1

This also fixes a little flaw for the swapped case: a check for
glXRenderLarge was missing.

delete trailing whitespace, break long lines, always emphasize nxagent
and nxproxy, emphassize options identcially everywhere

Fixes: ArcticaProject/nx-libs#536

Allowing overrides via NX_TEMP and TEMP breaks system using
pam_tmpdir.so and most server infrastructure expects the location to be
fixed anyway.

Works around libtool bug related to using both -nostdlib and -pthread
(with the former dropping latter usage.)

Regression fix for f855b3b6. Caused FTBFS with Loop.cpp:2669:0: error: unterminated #ifdef (#ifdef TIME).

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.
