v2.0.0-beta193

Warning: this release breaks BC with previous beta releases

Improvements

• Adding initial support for blobs: now it's possible to copy an unmanaged C# struct into a byte array stored in Val using new Val.SetBlob< T >(..)/GetBlob< T > (..) API. This makes it possible to get rid of extra boxing when storing C# structs in Val.
• Removing allocating VM.Start(..) methods
• Adding FiberOptions enum support for extra tweaking of the started fiber
• Adding aggressive inlining hints for C# methods
• Using faster C# unsafe decoding of the bytecode
• Introducing optional bool argument: Fiber.Stop(.., bool with_children = false)
• Getting rid of 'frame0' in Fiber
• Optimizing frame exit routines
• Cleaning up unclaimed Fiber's results upon its restart
• Adding RefcList< T > convenience wrapper around List< T > with refcounting support which allows to pool lists
• Pre-allocating defer blocks for Frame and SeqBlock
• Getting rid of all code duplication related to execution of module's init code
• Cleaning FixedStack< T >, starting to use C# return ref semantics
• Improving compiler error handling and reporting

BC breaks

• ProxyType now uses NamePath for path instead of just a string. NamePath contains a list of path items.

Bugfixes

• Fixing Fiber double stop bug
• Fixing stale frame reference bug when starting a fiber via FuncPtr
