* align from serializer/deserializer
* AdapterAccess class
* helper class Serializer/Deserializer
* setError renamed to error
* deprecated registerBasesList from PolymorphicContext
* removed internal context from config, because it doesn't actually solve any problems, only allows to do same thing in multiple ways
* internal context from config, because it doesn't actually solve any problems, only allows to do same thing in multiple ways
* AdapterWriter/Reader classes, and their functionality is moved to `adapters`.
* UnsafeInputBufferAdapter, instead config option is provided to disable buffer read errors
* isValidState from stream output adapter, because it didn't provide any additional information that couldn't be queried directly on stream object.
## other breaking changes
* changed signature to all lambda methods, instead of accepting (T&) as only parameter, now accept (S& ,T& )
since it is no longer needed to store serializer/deserializer reference, this allows
to pass functors, function pointers or stateless lambdas
* BufferedSessions reworked, it was removed from core bitsery functionality, and instead ability to change read/write position was added for buffered adapter
* Growable extension now uses adapter reader/writer to directly change read/write position
* BufferedSessions reworked, it was removed from core bitsery functionality, and instead was added ability to change read/write position directly for buffered adapters
* if context is defined, in serializer/deserializer, it is passed as first argument by reference (instead of pointer). Other parameters are forwarded to input/output adapter.
* for adapters save first error that occured, and ignore all the others
* serializer/deserializer no longer owns contexts, it only have reference to adapter reader/writer
* adapter is now owned by adapter reader/writer
* context can no longer be null, and instead reference to context is stored in adapter reader/writer.
* context<T> will never return nullptr
* if context is optional contextOrNull<T> return null in case context is not defined
* setError for input adapters renamed to error
* context can no longer be null, and instead reference to context is stored in serializer/deserializer.
* context<T> returns reference instead of pointer
* if context is optional contextOrNull<T> return nullptr in case context is not defined
* context<T> and contextOrNull<T> also check if type is convertible, so it can work with base classes
(e.g. you can require base class of context in extension, but provided child implementation instead)
* renamed NetworkEndianness to Endianness in config
* MeasureSize adapter moved to separate file `/adapter/measure_size.h`
## improvements
* added quickSerialization/Deserialization overloads that can accept context as first parameter.
* added support for custom allocator(s) for pointer like objects. More information on how to correctly use custom allocation and pointers in general see [this](doc/design/pointers.md).
* inheritance context now accepts allocator
* added tests for BasicMeasureSize
* helper classes (FtorExtValue, FtorExtObject) for extensions, that reduce boilerplate when writing lambdas that accept serializer/deserializer and data.
* helper classes (FtorExtValue, FtorExtObject) to reduce boilerplate and improve readability in places where you need to provide (des)serialize function/lambda that uses extension.
e.g. instead of writing `s.container(obj, [](S& s, MyData& data) {s.ext(data, MyExtension{});});` you can write `s.container(obj, FtorExtObject<MyExtension>{});`
* added config options to enable/disable checking input adapter and data errors (`CheckAdapterErrors` and `CheckDataErrors`) (default is enabled)
## bugfix
* fixed enabledBitPacking where writer and internal context states was not restored properly after exiting from this function
## todo
* write tests for inheritance context with allocator
* add allocator support for polymorphic and pointer linking contexts
* flexible syntax, enable option (using config) to use compactvalue for fundamental types by default (it should be off to preserve ABI breaking change).
* simplify overall usage by making adapterwriter/reader base class for adapters using CRTP.
* improve SmartPtr by allocating shared_ptr control block using provided allocator
* rename "flexible" to "brief_syntax"
