Persistent Memory pool management support library

 libpmempool provides a set of utilities for management, diagnostics and repair
 of persistent memory pools. A pool in this context means a pmemobj pool,
 pmemblk pool, pmemlog pool or BTT layout, independent of the underlying
 storage. The libpmempool is for applications that need high reliability or
 built-in troubleshooting. It may be useful for testing and debugging purposes
 also.
