addpart command is switched to use this function.

cmdlinepart: make argument types safer ...

The return size should be loff_t to support partitions bigger
than 4G. Also use const for the devname and endp.

move cmdline partition parsing code to separate file ...

So it's no longer local to the addpart/delpart code and can be used
from other code.

memtest: Fix SDRAM size calculations ...

Calculating the size and end of the test region as

  end = PAGE_ALIGN_DOWN(bank->res->end) - 1;
  size = end - start + 1;

is wrong. For an example resource of

  start = 0x80000000, end = 0x8fffffff

end results in:

  end = PAGE_ALIGN_DOWN(0x8fffffff) - 1 = 0x8fffefff

instead of 0x8fffffff. The size is then calculated to

  size = end - start + 1 = 0x8fffefff - 0x80000000 + 1 = 0x0ffff000

instead of 0x10000000

The correct way to do this is to calculate the real size and apply a
PAGE_ALIGN_DOWN afterwards:

  size = PAGE_ALIGN_DOWN(bank->res->end - start + 1) = 0x10000000

Fix this in three different places.

commands: loady: fix bug with netconsole ...

Netconsole doesn't have a baudrate. Loady supposes a console has one,
and tries to compute the console's baudrate variable value, regardless
of its existence.

This triggers a NULL pointer dereference on netconsole. If attempting
loady on a netconsole is a bit useless, barebox should not panic. Fix
this by checking the variable exists before reading its value.

Add support for non volatile variables ...

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:

nv user=sha; saveenv
