Don't rely on compiler for metadata packing to 4KiB size and add
reserved fields manually. For compatibility reasons against metadata
relying on automatic padding the reserved fields are also added in-between
existing fields as needed.

Adds user write throttling - since writing to cache must be balanced
against the ability to compact the data to the base device, this
throttling mechanism allows for a smoother, more stable performance
levels - tying the user write speed to the compaction drain speed.

Adds ability to send trim commands to FTL - only 4MiB aligned requests (both
for offset and length of request) will be processed. During a trim
operation an L2P page (containing 1024 4B entries, 1 per user LBA; which
is where the 4MiB alignment comes from) will be marked as unmapped.
After this point any L2P access to that page will actually set the
entries themselves as FTL_ADDR_INVALID. This is done to make the trim as
fast as possible, since for large requests it's probable that most of
the L2P pages aren't actually in DRAM.
