nvvar_add results in two calls to dev_set_param:
- once when the existing global variable is found and set
- once more when setting the nv variable
This results in an annoying but ultimately harmless message on startup:
ERROR: USB multi gadget already registered
ERROR: failed to create nv variable usbgadget.autostart: Device or
resource busy
Avoid this by ignoring usbgadget.autostart=1 after it succeeded once.
This issue should only affect $global.usbgadget.autostart, because all
other global variables are "simple" meaning that they have no setters
triggered.
Fixes: 5a5c5178e7dc ("usbgadget: autostart: support delayed usbgadget.autostart=1")

So far, global.usbgadget.autostart=1 from the shell was without effect,
because the variable is only evaluated once at postenvironment_initcall.
Use the new globalvar_add_bool() to allow acting on the variable being
true at any time. This is necessary for scripts that want to enable
the usbgadget autostart functionality selectively without themselves
hardcoding the particularities of what is exported.

strerrorp() is only used along with printf. We now have a format
specifier for printing error pointers directly, so use that and
remove strerrorp.

BAREBOX_MAGICVAR now generates a unique identifier automatically,
so we can convert users of BAREBOX_MAGICVAR_NAMED to the simpler
BAREBOX_MAGICVAR macro.

There is nothing USB-specific in the defined usbgadget.fastboot_*
variables. Rename them to be usable also for the UDP fastboot transport.
The usbgadget.fastboot_function variable is used to define the files and
devices accessible with the erase and flash commands. Since "function" is
a term from the USB specification and the Fastboot specification uses the
term "partition", we rename that variable to "fastboot.partitions".

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'.
