blspec: fix crash when trying to boot from loop mounts ...

When trying to boot from a loop mount path, the blspec code passes a

partitions: dos: Treat all extended partition types equally ...

Creating logical DOS partitions with fdisk (Fedora 27, fdisk from
util-linux 2.30.2) results in extended partition of type 0x05 being
created on the device. Partitioned like this, device is succesfully
recognized by Linux, but, due to algorithm in dos_partition(), not
Barebox.

Looking closer at the actual contents of MBR shows that while marked
as "Extended partition with CHS addressing" that partition still have
all of the LBA adressed fields filled correctly.

Given the above and the fact that similar code in Linux
kernel (block/partitions/msdos.c) does not make a distinction between
types 0x0f and 0x05, port Linux's is_extended_partition() and convert
the code to treat types 0x05, 0x0f and 0x85 the same way.

file_list: Add ubi flag ...

This flag is added to better support flashing UBI image with Android
sparse images. Android fastboot splits images which are bigger than the
free memory into multiple images which are then transferred in multiple
fastboot sessions. In a session which is not the first one we can no
longer detect if an image is a UBI image or not, so we need a flag to
make this explicit.

of: base: use root_node compatible as suggestion for a hostname ...

on some SoCs we can use generic PLL and RAM initialization. In this
cases we create board file only to provide a host name.
With this patch host name will be created from device tree compatible.
For example:
 compatible = "board_vendor,board", "chip_vendor,soc"
the host name will be:
 "board"

This function will not overwrite a host name which is already set by
board or machine code.

ubiformat: Add ubiformat write function ...

The ubiformat C API expects an image file as argument. With upcoming
Android fastboot sparse image support we can no longer provide a
complete image anymore. With this patch we can write an image in
multiple chunks after we've formatted a MTD device with ubiformat.

ubiformat_write will skip the EC header in both the MTD device we
write to and also the image we read from, so we can flash an image
on a MTD device containing EC headers already.

When uimage crc fails, the error handling path call uimage_close in

bootm_open_os_uimage to avoid double uimage_close.

nvvar: when setting a nvvar to NULL just free the content ...

When a nvvar is about to be removed then it is set to NULL
by barebox. This means for the variable to free it's memory.
In this case also do not pass the value to the corresponding
globalvar, since that would set the globalvar to NULL aswell,
but we want to keep its current value.
