But also fixes some issues.

Finally remove the dependency on epoll and use "select" instead.

The linker has a different behaviour in Fedora, it needs all the
libary names, it does not build the tree the same way as other linux.
Fixed thanks to Anthony Mallet

Update version after switching from epoll to select as socket
mecanism.

The new version fix an important bug

Fix the compilation on Ubuntu-12.10, where they clean a bit the standard
include mess

This library includes a server and client definition. It should be used in
any software that has to communicate with HATP.
When a client starts, it registeres itself to the server. Then when another
client wnats to communicate it needs to use the name of the first client,
the server will relay the message to the correct client. There must not
be two clients with the same name because if one leaves then when the second
will leave ther server will crash.
