Check that a variable defined in /config/environment is found in the
run-time environment, and that clearing fdt_env_path from within that
node works.

At present we use the linker list directly. This is not very friendly, so
add a helpful macro instead. This will also allow us to change the naming
later without updating this code.

At present this function returns 1 on success and 0 on failure. But in
the latter case it provides no indication of what went wrong.
If an attempt is made to delete a non-existent variable, the caller may
want to ignore this error. This happens when setting a non-existent
variable to "", for example.
Update the function to return 0 on success and a useful error code on
failure. Add a function comment too.
Make sure that env_set() does not return an error if it is deleting a
variable that doesn't exist. We could update env_set() to return useful
error numbers also, but that is beyond the scope of this change.

Move this header out of the common header.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

There is black magic in the file conftest.py that list
all the test unit. Then, all those test unit are called
in pytest. This call is done with the end of the name
(for example checksum if the full name is bloblist_test_checksum).
The result is that only test for dm are really executed.
by pytest, all others tests are listed but never executed.
This behaviour happens because the dm test unit only check
the end of the name and others tests checks the full name.
To fix this issue, I've added a prefix to the function
cmd_ut_category, and this prefix is removed when looking
for the unit test.

Avoid using a typedef here which is unnecessary. Add an 'env_' prefix to
both the enum and its members to make it clear that these are related to
the environment.
Add an ENV prefix to these two flags so that it is clear what they relate
to. Also move them to env.h since they are part of the public API. Use an
enum rather than a #define to tie them together.

U-Boot is not supposed to use typedef for structs anymore. Also this name
is the same as the ENTRY() macro used in assembler files, and 'entry'
itself is widely used in U-Boot (>8k matches).
Drop the typedef and rename the struct to env_entry to reduce confusion.

If CONFIG_UNIT_TEST is enabled we should enable the individual tests by
default to ensure good test coverage.

Only first previously deleted entry was recognized, leading hsearch_r
to think that there was no previously deleted entry. It then conluded
that a free entry was found, even if there were no free entries and it
overwrote a random entry.
This patch makes sure all deleted or free entries are always found and
also introduces constants for the 0 and -1 numbers. Unit tests to excersise a
simple hash table usage and catch the corruption were added.
To trash your environment, simply run this loop:
setenv i 0
while true; do
setenv v_$i $i
setenv v_$i
setexpr i $i + 1
done

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

The logic to either iterate through a list of tests or pick a named test
is common to at lest two test suits. Move this logic into a new function
and call it from the environment tests.

Add a new "env" subcommand to the ut command.
This will run unit tests on the env code. This should be targetable to
any device that supports the env features needed for the tests.
