pblk: Physical Block Device Target

pblk implements a fully associative, host-based FTL that exposes a traditional block I/O interface. Its primary responsibilities are:

• Map logical addresses onto physical addresses (4KB granularity) in a logical-to-physical (L2P) table.
• Maintain the integrity and consistency of the L2P table as well as its recovery from normal tear down and power outage.
• Deal with controller- and media-specific constrains.
• Handle I/O errors.
• Implement garbage collection.
• Maintain consistency across the I/O stack during synchronization points.
