1.12.0-rc1

This release:
- Deprecates librpmem library and rpmemd tool.
Using the librpmem library API will result in warnings
and is no longer recommended. Those interested in a remote
persistent memory support should use the new rpma library.
- Introduces a new set of APIs in libpmem2 to perform asynchronous data
movement operations. To use this feature, software needs to include an
optional miniasync(7) dependency.
- Adds new API to machine safe read/write operations in the pmem2 library.
- Introduces support for movdir64b instruction for memory operation
functions in the libpmem2 library.
- Adds experimental support for RISC-V.

- common: supress false positve of '-Wunused-parameter'
