This matches behavior with kmod which has been the standard for a long
time at this point.

48dc80bbba modutils: merge module_entry and module_info to common
This merges the in-memory module info structures of modprobe
and depmod. This allows sharing hashing by modulename code
improving depmod runtime with almost factor of 2x.

9de69c024c modprobe: fix modprobe -r and parsing of /etc/modprobe.d
This fixes a regression introduced with commit 78854520 (modprobe:
revert checking for /, stop doing basename() on modprobe args,
2015-01-01) that broke modprobe options stored in /etc/modprobe.conf and
/etc/modprobe.d/*.conf.

This also fixes modprobe -r

The --show-depends and -a options can be used together due to upstream modprobe

- a lot faster (linear algorithmic complexity, smaller memory foot print)

- loading of aliases is now module-init-tools compliant
- blacklisting is done correctly (-b option added)
- module argument quoting done right
- depmod now correctly generates modules.symbols and modules.alias
