When reworking this code to fix other issues found by Coverity, I forgot
to ensure tmp_ep was always cleared before use.

As part of fixing the previously reported issues, it was missed that in
the case of mtdparts_init() we need to make sure that tmp_ep is long
enough to contain PARTITION_MAXLEN and a NULL termination. Then, to be
sure the buffer is NULL terminated, zero the entire buffer rather than
just ensuring the first character is NULL.

Now that sandbox is building cmd/mtdparts.c Coverity has looked at the
code and found a number of issues. In index_partitions() it is possible
that part will be NULL, so re-work the checks and debug statements to
take this into account. We have a number of string buffers that we
print to in the exact size of, and use string functions on, so we need
to ensure they are large enough to be NULL terminated. In
device_parse() it is not possible for num_partitions to be 0 (we would
have hit a different error first) so remove logically dead code.
Finally, in parse_mtdparts() if we have an error we need to free the
memory allocated to dev.

We are now using an env_ prefix for environment functions. Rename these
other functions as well, for consistency:
getenv_vlan()
getenv_bootm_size()
getenv_bootm_low()
getenv_bootm_mapsize()
env_get_default()

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.
Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

commit 06a040a31b ("cmd: mtdparts: fix null pointer dereference in parse_mtdparts")
removed the initialization of a pointer variable, which is
subsequently used in a debug() call. This produces an uninitialized
variable warning, when compiling with DEBUG defined.

CMD_MTDPARTS is something the user might or might not want to select, and
might depends on (or be selected by) other options too.
This is even truer for the MTDIDS_DEFAULT and MTDPARTS_DEFAULT options that
might change from one board to another, or from one user to the other,
depending on what it expects and what storage devices are available.
In order to ease that configuration, add those options to Kconfig.

Some CPUs contains boot ROM code capable reading first few blocks
(where SPL resides) of NAND flash and executing it. It is wise to
create separate partition here for SPL. As block size depends on
NAND chip used, we could either use worst case (biggest) partition
size or base its size on actual block size. This patch adds support
for the latter option.

Boards which are defining default mtdparts often need them early
in boot process (to load environment from UBI volume, for example).
This is currently solved by adding mtdparts and mtdids variable
definitions also to default environment. With this change, default
partitions are used by default unless explicitely deleted or
redefined.

In case there is no mtdparts variable in relocated environment,
NULL is assigned to p, which is later fed to strncpy.
Also function parameter mtdparts is completely ignored, so use it
in case mtdparts variable is not found in environment. This
parameter is checked not to be NULL in caller.

A private buffer is used to read mtdparts variable from non-relocated
environment. A pointer to that buffer is returned unconditionally,
confusing later test for variable presence in the environment.
Fix it by returning NULL when getenv_f fails.

This makes it easier to find a file since the prefix does not get in the
