Add Elf 32 Support to Courgette.
This change takes advantage of recent refactoring and adds support for
Elf X86 32 executables to courgette. It should have no effect on handling
of Windows PE executables.
We have planned ahead to be able to restrict the code size of the courgette
library in different cases to reduce patcher sizes, but this change does
not yet take advantage of that (all platforms are supported everywhere).
Also, the patcher class currently contains a very small amount of Elf/PE
specific code for recreating relocation tables that cannot (currently) be
compiled out.
BUG=chromium-os:22149
TEST=Please verify that Chrome/Chromium patches can still be generated and
work.
Also, please see how much the updater executable which is downloaded to
users has changed in size since R16.
