LW Support 1.0.0

LW Support project is a C++ support library for Linux.
Although it has gone through many iterations of design and goal, LW Support is designed to expose C library functionality in an object-oriented manner (for example, by providing classes for POSIX I/O).
In fact, one of its main features is the I/O hierarchy it uses -- objects such as TCP sockets and serial ports share the same base class.
Enhancements:
Major changes:
- IOListen and IOCallback, deprecated for a long time, have now been completely removed.
- The build system has been upgraded.
- Documentation is now packaged separately.
All changes:
- IOListen and IOCallback, which were deprecated, have been removed. The corresponding interface from NetServer was also removed. The I/O loopback example which used these was removed.
- The build system has been upgraded. It now has proper support for shared library naming semantics and an improved pkg-config script.
- A dependency on libutf8++ has been introduced. Over time, the built-in string conversion routines will be deprecated in favour of libutf8++.
- Minor build fixes which came to light with a new compiler/64-bit architecture.
- Pre-built documentation is no longer included in the source tarball, but is available separately.
