New Revision: 253317<br>

Log:<br>
Add Pythonic language binding wrapper generation script.<br>
<br>
This is only used by Xcode at the moment. It replaces the<br>
buildSwigWrapperClasses.py and related per-script-language<br>
scripts. It also fixes a couple bugs in those w/r/t Xcode<br>
usage:<br>
<br>
* the presence of the GCC_PREPROCESSOR_DEFINITIONS env var<br>
should not be short-circuiting generation of the language<br>
binding; rather, only if LLDB_DISABLE_PYTHON is present<br>
within that environment variable.<br>
<br>
* some logic around what to do when building in "non-Makefile"<br>
mode. I've switched the handling of that to be on a<br>
"--framework" flag - if specified, we build an OS X-style<br>
framework; otherwise, we go with non.<br>
<br>
Putting this up now only attached to the Xcode build so<br>
others can look at it but not be affected by it yet.<br>
After this, I'll tackle the finalizer, along with trying<br>
it locally on Linux.<br>
