Eugene Syromiatnikov 2aa8019903 macros.kmp: add post-install kmod processing hooks
The enablement of debuginfo generation broke custom %install scripts
that perform module signing, and in an attempt to address that,
additional hooks are added that can be used for module compression,
signing, and other means of kmod processing.

* macros.kmp (redhat_kmp_has_post_hooks): New macro, set to 1.
(kernel_module_package_release): Add __brp_kmod_pre_sign_process,
__brp_kmod_sign, __brp_kmod_post_sign_process, __brp_kmod_compress,
and __brp_kmod_post_compress_process to the generated
__spec_install_post.

## An ugly hack: we want kmods to be processed by find-debuginfo,
## but it processes only files with executable permission set.
## It is important now since, as of now, if debuginfo package
## is enabled (and it is enabled), there's an RPM build error
## as a result of lack of ether absence or emptiness of
## debugsourcefiles.list (which is likely a bug in RPM, but it looks
## like that there's no obvious fix and apparently no one have
## any issues with this).
## In order to minimise intrusiveness, usually (in Red Hat-built kmod
## RPMs) *.ko files just have executable permission being set as a part
## of %build section. There are two caveats with kmp, however:
## * We have no control over %build section itself (and it wasn't
## required previously)
## * Changing the criteria used in find-debuginfo.sh/brp-strip
## for selecting files that have to undergo debug section separation
## may introduce regression.
## As a result, we insert additional hooks in __spec_install_post
## (__brp_kmod_set_exec_bit in the beginning and
## __brp_kmod_restore_perms in the end) that (temporarily) set
## executable permission for *.ko files so find-debuginfo.sh will pick
## them up.
## Unfortunately, __spec_install_post's body is copied here since
## we want that __debug_package macro expansion has been performed
## lazily and it looks like RPM has no ability to provide a body
## of a macro verbatim.
