Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=41443 Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=42304 I have added more xcb connection error states at xcb.h header. Also I have removed global error_connection variable, and added an interface that returns connection error state. TBD: I will segregate errors states in a separate header file and try to provide more precise error states, in future. Also I will give patch for libX11, in that patch xcb_connection_t::has_error will be passed to default io handler of libX11. This value can then be used for displaying error messages.

About libxcb
============
libxcb provides an interface to the X Window System protocol, which
replaces the current Xlib interface. It has several advantages over
Xlib, including:
- size: small, simple library, and lower memory footprint
- latency hiding: batch several requests and wait for the replies later
- direct protocol access: interface and protocol correspond exactly
- proven thread support: transparently access XCB from multiple threads
- easy extension implementation: interfaces auto-generated from XML-XCB
Xlib can also use XCB as a transport layer, allowing software to make
requests and receive responses with both, which eases porting to XCB.
However, client programs, libraries, and toolkits will gain the most
benefit from a native XCB port.
