bbu: Add "handler" parameter to barebox_update() ...

Add "handler" parameter to barebox_update() and remove the code that
was respondible for header lookup before. With this change finding
appropriate handler is caller's responsibility, which makes it
possible to implement custom handler lookup/existence check, chache
it, and then re-use it without calling handler_find_by_* functions for
the second time.

commands: of_property: copy value instead of resizing ...

Commit 748d1b8 adds the fixup feature to the above command. With this commit an
unwanted free(data) on the freshly set property value is done if someone tries
to set the value of an already present property (not the case for a new
property). Furthermore in fixup mode the pointer fixup->data is freed when the
fixup function is called more than once. This leads to a hanging system after
calling of_dump -F many times.
Fix this issues by copying the data to a new allocated memory area like a new
property is created.

nand command: fix null pointer when adding/deleting a bb device ...

Commit 40ee300 introduces info option about bad blocks. The open()
function call is therefore moved out from mark good/bad block to use the
filedescriptor in info option too. If someone tries to add/delete a bb device
the optind variable is incremented and the open() call gets a null pointer.
Fix this issue by returning when the bb device is added/deleted.

of_node: clarify help text and do stricter commandline parsing ...

To create an oftree node /path/node I tried after reading the help text
of of_node:

	of_node -c /path node

similar to the syntax of of_property. This didnt result in any output
but still failed to do what I meant.

So clarify the help text to not suggest there are two parameters and
return an usage error if still two (or more) names are passed.

commands: oftree: kill oftree -f ...

Being able to free the live device tree seemed like a good idea in the
early days of device tree support when the first boards were brought up.
It turned out to be illusory that noone stores pointers to the live tree
which become invalid when oftree -f is executed. Enough people stumbled
upon crashed boards with this option, so remove it finally.

commands/of_node: add option to apply changes as fixup ...

Analogous to the of_property command, add an -f option to the of_node
command. This option defers the device tree modification until boot
time and thus applies the modification as a fixup on the linux device
tree.

commands: i2c_write: enable reg == 0 too ...

This commit fixes the mistake introduced in the commit 34fadb685905
('commands: i2c_write: enable raw write to address').
The intended behaviour for i2c_write command is
"use raw i2c write only if reg address is not defined".
Before the commit 34fadb685905 reg address == 0
was acceptable. After the commit 34fadb685905 reg address == 0
became unacceptable ("undefined") and will lead to raw i2c write.
