Added try_reserve to VecWriter, Vec, VecDeque and HashMap Made the OOM test succeed on the latest nightly Made the OOM check work on nightly Disabled stable checks for now Removed feature that is stable in current nightly Fixed issue where Box<[T]> would not do the size limit check Added a drop guard to `impl<T> Decode for Vec<T>` to make sure memory is not leaked when T::Decode panics Made the implementation of `VecWriter` use less lines of unsfe Fixed errors while merging
…did not fix the runtime error

With Rust 1.57, several
try_reservemethods have been stabilized. This PR makes bincode take advantage of this.A nightly flag can be set to disable all fallible allocations. This is currently blocked on the following features:
allocator_apitracking issuenew_uninittracking issuetry_reserveon more collections: tracking issueAnd uses the following features, although this could be implemented manually:
maybe_uninit_slicetracking issuevec_spare_capacitytracking issue (stabilized on jan 18, 2022)Other useful issues:
Vec::push_within_capacityto reduce the amount of unsafe code to replaceVec::pushtracking issue
