1.3.0

Added

• Stable toolchain alloc crate support for no_std code via the alloc
  feature. This requires Rust 1.36 or later.
• ByteData support for std::mem::MaybeUninit types that wrap other
  ByteData types (e.g. MaybeUninit<usize>) when using Rust 1.36 or later
  or when the unstable feature is enabled.

Changed

• Add local_inner_macros modifier to utility macro declarations
  (array_type_for_bytes!, cache_aligned_zeroed_for_markers!, etc.),
  allowing them to be imported individually via use statements in Rust 2018
  code without needing to import any other macros that they may call.
• Update example and test code to use std::mem::MaybeUninit as appropriate
  when working with uninitialized memory. The now-deprecated
  std::mem::uninitialized() function is only used for tests on legacy
  systems and is not included in any generated documentation.
• Include recommendations to use arrays and slices of std::mem::MaybeUninit
  elements if possible for uninitialized memory storage to the documentation
  for Scratchpad::static_new(), Scratchpad::static_new_in_place(),
  uninitialized_boxed_slice(), uninitialized_boxed_slice_for_bytes(), and
  uninitialized_boxed_slice_for_markers(), as well as a note in the "Known
  Issues" section of the crate-level documentation.
• Add #[repr(C)] attribute to CacheAligned in order to guarantee
  consistent data layout. CacheAligned is correctly sized and aligned in
  practice with the default Rust repr, but the Rust repr technically
  doesn't guarantee any specific data layout; specifying the C repr helps
  us avoid any edge cases that may arise. Existing code should still behave as
  normal.
• Updated Travis CI configuration to use clippy and rustfmt from the
  stable toolchain, and updated the code accordingly (based on the 1.36.0
  toolchain versions).
• Various minor API documentation improvements.
