Adding autoheader generated files to git

[Ralf Corsepius]

Hi,

As mentioned briefly in another thread, I intend to gradually add the 
generated sources to git.

In an initial (moderately experimental) step I am going to add the 
autoheader generated source files to git:
- bspopts.h.in
- config.h.in

Theoretically, this step should be entirely transparent to users, except 
that there is a possiblity of facing conflicts upon "git pulls/checkout" 
in existing git checkout after these were added to git.

In this case try
./bootstrap -c
git pull
./bootstrap


  If your checkout does not contain any modifications, git should not 
report any differences.

  If your checkout contains modifications, you may see reports on 
"untracked files" and new diffs.
