bootm: Move bootm options to common/Kconfig ...

bootm has a C API, so the bootm options have to depend on the
option providing the bootm code (CONFIG_BOOTM), not on the
option providing the command (CONFIG_CMD_BOOTM). Fixing the
dependencies makes it possible to fully use bootm from C without
enabling the bootm command support.
This also removes the CMD_ prefix from the options which means
we have to update the defconfigs aswell.

Kconfig: Create Kconfig symbol for NVVAR ...

nvvar support not only needs globalvar, but also persistent
environment storage. Add a separate default-y option which
depends on ENV_HANDLING for this case. Make the option visible
to let the user decide whether he wants to have this option
and add a help text to make this decision easier.

Kconfig: Make ENV_HANDLING visible ...

ENV_HANDLING is usable even without explicit loadenv/saveenv command
support. Instead of selecting this option from loadenv/saveenv, make
this option visible. loadenv/saveenv can then depend on ENV_HANDLING
rather than selecting it. This reduces Kconfig dependencies hassles.

Kconfig: Make GLOBALVAR visible ...

Currently global environment variables are only enabled when the
"global" command is enabled. In fact, they could be used even with
the "global" command disabled, so make the GLOBALVAR option visible.
While at it, add a help text for this option.

state: Fix Kconfig dependencies ...

State support does not need OF_BAREBOX_DRIVERS and never did, so drop
the dependency there. It's the state driver which needs of_find_path(),
since this symbol now is always enabled when OF is enabled, we don't
have to add the dependency to the state driver, but instead can depend
on OFDEVICE. We could depend on OF instead, but compiling the state
driver without OFDEVICE makes no sense.

bootm: add initial FIT support ...

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.

Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.

barebox remote control ...

This adds the ability to control barebox over serial lines. The regular
console is designed for human input and is unsuitable for controlling
barebox from scripts since characters can be lost on both ends, the data
stream contains escape sequences and the prompt cannot be easily matched
upon.
This approach is based on the RATP protocol. RATP packages start with a
binary 0x01 which does not occur in normal console data. Whenever a
0x01 character is detected in the console barebox goes into RATP mode.
The RATP packets contain a simple structure with a command/respone
type and data for that type. Currently defined types are:

BB_RATP_TYPE_COMMAND (host->barebox):
	Execute a command in the shell
BB_RATP_TYPE_COMMAND_RETURN (barebox->host)
	Sends return value of the command back to the host, also means
	barebox is ready for the next command
BB_RATP_TYPE_CONSOLEMSG (barebox->host)
	Console message from barebox

Planned but not yet implemented are:

BB_RATP_TYPE_PING (host->barebox)
BB_RATP_TYPE_PONG (barebox->host)
	For testing purposes
BB_RATP_TYPE_GETENV (host->barebox)
BB_RATP_TYPE_GETENV_RETURN (barebox->host)
	Get values of environment variables

crypto: fix selecting of digests ...

SHA1 is meant as a boolean option which is true when sha1 support is available.
This works because the providers (DIGEST_SHA1_GENERIC and DIGEST_SHA1_ARM) have
a 'select SHA1'. However, consumers like the sha1sum command do a 'select SHA1'
to enable SHA1 support. This of course does not work; selecting SHA1 will not
select any of the SHA1 providers.

This is broken for all digest consumers. We have to explicitly select a digest
provider, that is DIGEST_*_GENERIC to enable the corresponding digest.

This means now we will always have the generic digest in the binary, even
when an optimized one is enabled. There is no sane way in Kconfig to
"select provider for feature xy", so let's live with the overhead in the binary.
