Pull pin-init updates from Gary Guo:
"User-visible changes:
- Merge the '__pinned_init' and '__init' methods and make 'Init'
a marker trait.
- Introduce public APIs 'raw_init' and 'raw_try_init' to prevent users
from needing to invoke the internal '__pinned_init'/'__init' methods.
- Emit errors for duplicate '#[pin]' attributes.
- Link 'Zeroable::zeroed' and 'pin_init::zeroed' in documentation.
Other changes:
- Fix unwind safety issues.
- Clean up lint 'allow' and 'expect's.
- Overhaul '#[cfg]' handling to pave the way for tuple structs and
self-referential structs.
- Mark many functions as '#[inline]' for better codegen with '-C
opt-level=s' ('CC_OPTIMIZE_FOR_SIZE')."
