AdaSockets 1.9-alpha1 is available

I'd like people to test the AdaSockets 1.9-alpha1 release. In the last
few days, I have rewritten large parts of AdaSockets to use
GNAT.Sockets while trying to be 100% compatible with the established
usage.

In this release, there are no more system-specific files as
GNAT.Sockets takes care of the system-dependent parts already.

You can get it from:

The release notes for this version are:

| * New in AdaSockets 1.9
|
| AdaSockets 1.9 is a rewrite of large parts of AdaSockets. It is based on
| GNAT.Sockets while keeping an interface compatible with the 1.8.x branch
| of AdaSockets.
| 
| Some rarely used user-visible subprograms and constants have been removed:
|   - Sockets.Customized_Setsockopt
|   - Sockets.Socketpair
|   - Sockets.SO_REUSEPORT
|   - Function depending on internal type Sockets.Types.In_Addr in
|     package Sockets.Naming

It has been tested on Debian GNU/Linux x86 with gcc-4.1 and current
gcc development branch as well as on SunOS 5.10 Sparc with GNAT Pro 6.0.1.
