Introduce non volatile device variables ...

Non volatile device variables are used to make device parameters
persistent. They are like normal non volatile variables, but set
the values of the device parameters with the corresponding name.
Every nv variable beginning with nv.dev is a non volatile device
variable. They have the form nv.dev.<devname>.<paramname> and act
on the parameter <paramname> of the device named <devname>.

The non volatile device variables are designated for example for
video modes, ethernet device ip addresses or mtd partitioning.

ubiformat: Fix formatting devices with unreadable areas ...

When parts of a Nand device are not readable due to excessive bit flips
we should not bail out with an error as this means we can never repair
the device by flashing a fresh image using ubiformat. Instead, treat a
failed read as a corrupt block and ignore the read failure.

parameter: Use strtobool ...

Use strtobool to convert the input string to a boolean type.

string: Introduce strtobool ...

We have at least two places which convert a string to a boolean type,
so create a common function for this. strtobool treats

- any positive (nonzero) number as true
- "0" as false
- "true" (case insensitive) as true
- "false" (case insensitive) as false

Every other value results in an error and the input *val is not
modified. The caller is expected to initialize *val with the correct
default before calling strtobool.

string: Fix (v)asprintf prototypes ...

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code
with userspace code. Change the prototypes for (v)asprintf to match
the glibc prototypes. Since the current (v)asprintf are convenient
to use change the existing functions to b(v)asprintf.

lib: declared buffer is too small to hold string ...

Displaying an unsigned 64-bit integer can be represented by up to 20
characters. The 20 bytes buffer reserved to store the formatted string
"%llu Bytes" is to small: (20 + 6) = 26. Hence, a bigger buffer is reserved
to hold this string.

decompressors: Use malloc/free wrappers ...

The decompressors are used both in a regular image and also for image
decompression. Both need different malloc implementations. Using
malloc/free directly in the decompressor code easily leads to include
file conflicts, so use MALLOC/FREE which can be defined correctly for
the two different usecases.
