Libpmemobj-cpp Version 1.8

This release moves persistent array/vector/string/concurrent_hash_map out from experimental namespace and directory. It means that the abovementioned containers are guaranteed to have a stable API and on-media layout. They are placed now in include/libpmemobj++/container/ directory and pmem::obj namespace.

This release introduces also a new experimental container - persistent segment vector with templated segment policies.

New features:

• experimental persistent segment vector container

Bug fixes:

• fixed insert method in persistent vector
• fixed move assignment operator in persistent array

Other changes:

• extended error messages in exceptions
• added examples with simplekv using persistent containers
• added modifiers methods for persistent string
• added template locks for concurrent_hash_map
• added layout versioning for concurrent_hash_map

Optimizations:

• concurrent_hash_map insert method implemented with tx
• optimized snapshotting in persistent vector/string
