Most tests don't have this. It helps to keep the test declaration
clearly associated with the function it relates to, rather than the next
one in the file. Remove the extra blank line and mention this in the
docs.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

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.

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.

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
