libcs3 refactor merge

Removed dependency on libcs3.a because Codesourcery does not provide the
source for it.

We now link against a modified libcs3-lanchon-stm32.a built from parts
in public domain from Lanchon, and a start_c.c from Codesourcery that is
licensed under a permissive license.

Also removed all of the extra linker cruft from the stm32conf directory.

The linker files now live in support/ld
The openocd scripts now live in support/openocd
The udev rules and copy-to-ide scripts now live in support/scripts
The source lives in support/ld/libcs3-lanchon-stm32.tar.gz
