blpec: rename struct lspec -> bootentries ...

The code in common/boot.c collects the different boot entries in
lists of type struct blspec, eventhough many of them may not be
bootloader spec entries but for example boot scripts. This is the first
step of separating the data structures from boot entries and bootloader
spec: As struct blspec is merely a container for collecting boot entries
We simply rename struct blspec to struct bootentries. No functional change.

include: Move bulk of boot.h to bootm.h ...

The majority of the stuff currently in include/boot.h is about bootm
code implemented common/bootm.c. To be more consistent move it to a
new file include/bootm.h.

nv: Allow to set/remove multiple variables with one command ...

It's convenient to set/remove multiple nv variables in one go. With

exactly one nonopt.

nv: Add option to explicitly save nv variables ...

We now have code to save the nv variables without saving the
rest of the environment. This gives us the possibility to explicitly
save the nv variables. This patch adds an option to the 'nv' command
for this.

bootm: Move magicvar descriptions to common/bootm.c ...

Now that the bootm code can be used without the command, we have to

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.

bootm: Optionally add a root= option to Kernel command line ...

It becomes a common case that the Kernel is loaded from the filesystem

automatically append the root= option to the kernel command line. This
is done when global.bootm.appendroot is true.

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
