[RFC] Adding new files, for new port to Interix (Services For Unix)

Before any initial commit, could you please go through them with a fine 
tooth comb and eliminate anything obvious.  See 
http://sources.redhat.com/gdb/current/ari/ for a reference.  You need to 
at least work through Fixed (Critical), Coding and Deprecated 
(interestingly ``register'' isn't yet listed under any of those :-)

The move to commit the Ada files and have them slowly cleaned up was an 
experiment.  Until that experiment is finished I'm reluctant to see 
other similar sized files accepted under that same loose criteria.

>>   - check-in the changes in the configury machinery in order for GDB to
>>     configure
>>   - check-in the minimal changes to allow GDB to build
>>   - And then finally check-in the remaining changes that make GDB work.
>>     For the curious, my regression testsuite results show about 6600
>>     passes, and 1200 failures.
