- When _LIBUNWIND_SUPPORT_COMPACT_UNWIND is defined in config.h, define it to "1" like the other macros. These macros are still checked using "#if defined(...)", however.
- Make findUnwindSectionsByPhdr static to avoid a potential ODR issue if the header is included in more than one TU.
- Include libunwind.h in AddressSpace.hpp before using _LIBUNWIND_ARM_EHABI.
- Rename ProcessFrameHeaderCache to TheFrameHeaderCache, because some configurations (e.g. Android / hermetic static libraries) can have one cache per shared object in the process. (When there are more copies, it's more important not to waste memory in the cache.)
- Add 3 missing header files to LIBUNWIND_HEADERS.
