Use global variable dfu_function to autostart DFU. As similar code
is used to start multifunction gadget using command, move common
code to common/usbgadget.c and consolidate it.
It turned out that '-s' option of usbgadget command does nothing,
so remove its help text and make it function as '-a'.

This adds reference counting to the bootchooser. Instead of creating a
new bootchooser instance with each bootchooser_get() we return a
reference to the existing bootchooser.
This makes the behaviour consistent when bootchooser_get() is called
multiple times.

Between creating a boot entry for bootchooser and actually using it the
underlying state may have been modified, so make sure to get a current
bootchooser when booting it, thus do a bootchooser_put after having
created the entry and a bootchooser_get again when booting it.

Calloc() implementation for TLSF does not correctly check for malloc()
failure which can result in a NULL pointer exception when trying to
calloc() extra large buffers.
Since both TLSF and dummy malloc implementations of calloc() are
exactly the same, pick implementation for the latter (which does
aforementioned check) and share it between the two.

For mtd devices the overlap check does not work as expected for two
reasons. First is that cdev->offset is 0 for mtd partitions, instead
cdev->mtd->master_offset has to be used. That could be fixed easily.
Second on NAND devices the environment is on the bb devices and not
on the raw nand devices which means we would need something to get
the mtd device from the bb device before doing the check.
Both issues are fixable, but the check was mainly done to catch cases
when an environment partition is created in the free space before the
first MBR/GPT partition on SD/MMC devices, so leave out the mtd case
for now.

Introduce two new RATP commands that allow running i2c read/write
operations, very similar in format to the already existing md/mw
RATP commands.
The messages are defined with a fixed 16-bit long register field, but
it will only be treated as a 16-bit address if I2C_FLAG_WIDE_ADDRESS
is set in the message flags field. If this flag is unset, the start
register address is assumed 8-bit long.
If the message includes the I2C_FLAG_MASTER_MODE flag, the start
register field is ignored and a i2c master send/receive operation is
performed.

Environment partitions are usually specified with their hardcoded offset
and size, either in the device tree or the board file. These partitions
potentially overlap with other partitions read from the partition table.
Overlapping partitions for sure have bad effects. Be more friendly to our
users and warn them when such a situation occurs and stop using that
partition for storing the environment.

The FCB block is protected with a ECC code which can correct 1bit errors
and detect 2bit errors. This works fine for all fields except the
fingerprint marker (Containing "FCB") and the version field. Here the ROM
chooses to check the correct value of the fields *before* running the ECC
correction. Thus a FCB is not used by the ROM anymore when it has a bitflip
in the fingerprint or version. For us this means we have to rewrite the FCB
in this case, so reject the faulty FCB in read_fcb_hamming_13_8() which
triggers a rewrite during the check operation.

When reading a firmware image the ROM only checks for a bad block when
advancing the read position, but not if the initial block is good.
Hence we cannot directly point to the first firmware block, but must
instead point to the first *good* firmware block.

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.
