  kdb: Refactor env variables get/set code (2021-04-14 13:47:09 +0100)

----------------------------------------------------------------
kgdb patches for 5.13

Exclusively tidy ups this cycle. Most of them are thanks to Sumit Garg
and, as it happens, the clean ups do result in a slight increase in
the line count. This is due to registering kdb commands using data
structures rather than function calls which, in turn, simplifies the
memory management during command registration.

In addition to changes to command registration we also have some dead
code removal, a clearer implementation of environment variable handling
and a typo fix.
