Hi Luis,

As per your suggestion [1], this is an attempt to refactor and split
optional code out of core module support code into separate components.
This version is based on branch mcgrof/modules-next since a97ac8cb24a3/or
modules-5.17-rc1. Please let me know your thoughts.

Changes since v1 [2]:

  - Moved module version support code into a new file

Changes since v2 [3]:

 - Moved module decompress support to a separate file
 - Made check_modinfo_livepatch() generic (Petr Mladek)
 - Removed filename from each newly created file (Luis Chamberlain)
 - Addressed some (i.e. --ignore=ASSIGN_IN_IF,AVOID_BUG was used)
   minor scripts/checkpatch.pl concerns e.g., use strscpy over
   strlcpy and missing a blank line after declarations (Allen)

Changes since v3 [4]:

 - Refactored both is_livepatch_module() and set_livepatch_module(),
   respectively, to use IS_ENABLED(CONFIG_LIVEPATCH) (Joe Perches)
 - Addressed various compiler warnings e.g., no previous prototype (0-day)
