The ioctl UBI_IOCATT has been extended with need_resv_pool parameter in
[1].
This parameter is used for deciding whether to reserve PEBs for filling
pool/wl_pool for target ubi device. This parameter will be effective
when fastmap is enabled, which will slow down the frequency of updating
fastmap by filling more free PEBs in pool/wl_pool. See details in [2].

The ioctl UBI_IOCATT has been extended with disable_fm parameter after
[1].
This parameter is used for disabling fastmap for target ubi device.
If 'disable_fm' is set, ubi doesn't create new fastmap even the module
param 'fm_autoconvert' is set, and existed old fastmap will be destroyed
after attaching process.
A simple test case in [2].

libubi.h includes ubi-media.h which was made private in the kernel a
long time ago. There are users of libubi.h, e.g. swupdate, which have to
have ubi-media.h available at build time with this inclusion.
However, libubi.h uses only one symbol from ubi-media.h. Define that symbol
in the header to enable using libubi.h without installing ubi-media.h.
Make up for the transitive symbol use in ubiformat.c by including ubi-media.h.

Now that we have per-UBI volume flags (for instance for skipping CRC
check when opening it) from the Linux header, let's add it to the
ubi_mkvol_request in libubi and assign the flags to ubi_mkvol_req from
the Linux header from ubi_mkvol.

Historically, the mtd-utils and ubi-utils were seperate packages. The
ubi-utils were at some point merged into the mtd-utils. They first
appeared in the release tar-ball in version 1.1.0 in their own
sub-hirarchy with their own buildsystem, readme, documentation, etc.
A lot of the duplicated stuff got centralized/removed over time.
This patch further cleans up the directory hirarchy duplication by
moving common libraries from the ubi-utils/ into the central lib/
and include/ directories in the top directory of the mtd-utils package.
This includes:
- libuib.a & libubigen.a used by the ubi utilities
- libscan.a currently only used by ubiformat
- libiniparser.a used by ubinize
