param: introduce param_bitmask ...

param_bitmask behaves similar to an enum, except that with a bitmask
multiple values can be specified. On the command line the bits are
represented as a space separated list of strings. In memory a
unsigned long * is used as backend storage, this can be modified
using the regular bitmap functions.

xstrdup: don't panic on xstrdup(NULL) ...

Instead return just NULL. This matches the behaviour of kstrdup in the
kernel and xstrdup in busybox.

This fixes a panic with CONFIG_CMD_MAGICVAR=y and
CONFIG_CMD_MAGICVAR_HELP unset in magicvar_add() where description is
always NULL.

getopt: Add support for '--' to stop option parsing ...

In some cases when commands have optional arguments it is necessary
to explicitly stop option parsing after the last nonpositonal option.
Add support for '--' to accomplish this as done in getopt(3) aswell.

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 ...

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.
