Extended ftl_band_read_lba_map() interface to provide
range of lba map to read.
Added ftl_xfer_offset_from_ppa() function for
calculating offset of read portion of lba map
based on ppa address from IO. This offset is
used for coping read lba map portion to internal
ftl buffer.

There's no point in synchronously returning an error from ftl_io_write
/ ftl_io_read as they're also reported in the IO's completion callback.
All errors are now reported through io->status.

Some of the internal IOs split the contiguous data buffer into multiple
iovecs to separate the requests. It's unnecessary and can be replaced
by checking the position within the data buffer.

There are no guarantees of the order of completion
of NVMe IO submission queue so wait for write completion
on specific chunk before submitting another write to it.
To control chunk occupancy split IO to child requests
and release chunk in IO completion callback.

Removing band from "free list" is moved from FTL_BAND_STATE_OPENING
to FTL_BAND_STATE_PREP state's change actions.
This will fix race condition when one band is prepared (erased)
and write pointer is trying to get next active band.

This patch adds core FTL (flash translation layer) submodules.
On regular SSDs the FTL is part of firmware, whereas Open Channel
enables moving it to the host and allows for having full controll
of data placement on the device.
Main functionalities added:
* logical to physical address map
* read / write buffer cache
* wear-leveling
* bad block management
