[PATCH v2 0/4] run-command.h: rename "env_array" to "env"

Follow-up 32ec72c3e1 (Merge branch 'ab/run-command', 2021-12-15) and rename the "env_array" member to simply "env" in the "struct child_process".

Changes since v1:

 * Added a commit to remove the coccinelle rule after its application,
   as suggested by Junio in
   https://lore.kernel.org/git/xmqqzgjdkxon.fsf@gitster.g/

 * Minor commit rewording for 4/4 to adjust for that new 3/4.

Ævar Arnfjörð Bjarmason (4):
  cocci: add a rename of "struct child_process"'s "env_array" to "env"
  run-command API: rename "env_array" to "env"
  cocci: remove env_array -> env migration
  run-command API users: use "env" not "env_array" in comments & names
