[dlls/dbgeng]: add initial stub dll implementation

[Volodymyr Shcherbyna]

Hello Alexandre,

I assume you were checking my patch (id: 68619) (
http://source.winehq.org/patches/data/68619) and marked it as "Apply
Failure".  If so, can you please double check? For the sake of the test, I
setup wine-git on another machine to see if this patch works, and it seems
to be OK. The following commands:

patch -p1 < 0001-Implementing-stub-version-of-dbgeng.dll-Debugger-Eng.txt
git add dlls/dbgeng/Makefile.in
./tools/make_makefiles
autoconf
./configure
make

properly integrate and build dbgeng in wine tree. I was following exact
guidelines from http://wiki.winehq.org/Developers-Hints , and I it seems
like the patch is OK, or I am missing something not documented on the wiki
:)

Well, I am a newbie in wine/linux, so, of course I can be wrong ...

P.S. I attach patch to this email just in case (the same patch I sent to
wine patch list).

Thanks,

-- 
avec meilleures salutations, Volodymyr
