Same as in WriteBuffer.cpp

Valgrind will complain about uninitialized data, but we are only
writing to the memory here.

as reported by valgrind

Should avoid copy-constructing objects again.

nxcomp/src/Log.cpp: don't confuse users with useless warning messages in case that a log line append operation was requested, but the message level has lower precedence than the current log filter.

Especially don't flush data out mid-append.
Doing so will lead to the next append operation failing.

Should fix messages queuing up indefinitely (until they are discarded at
program termination, at least) and missing messages in general.

Also handle errors due to missing buffers gracefully.

This error is surprisingly easy to trigger, so we should make sure that
the program does not crash.

Was dropped erroneously in cec31e2f.

Besides that being a useless construct to begin with, not all shells
even support parameters to echo. Nuke that abomination from or^Wthe
repository.

This should get rid of the infamous "800x600 screen size" issue
reproduced in X2Go whole display setups.

Fixes RPM builds building libNX_X11 with poll() support, even though we
explicitly disable it using --disable-poll in the main Makefile.

Fixes: ArcticaProject/nx-libs#540

nx-X11/extras/Mesa.patches_6.4.2/4002_no-special-glx-memfunctions.patch: include stdlib.h and string.h for memset, malloc and free prototypes.

Without that they are only implicitly defined - leading to build
failures on *SUSE.

I didn't mean to drop it in the first place in
07d30835 and
71bda0ed.

Dropping the sed hack was fine -  but we actually have to add these
flags to CDEBUGFLAGS as well.
