There is restriction on kdump_pre and kdump_post directives now that can be
specified only once in /etc/kdump.conf.
However, there are multiple components that need to use the directives.
This patch implements /etc/kdump/{pre.d,post.d} interface to set up multiple
binary and script files.
For example, users put multiple binary and script files under
/etc/kdump/pre.d directory as below:
# find /etc/kdump/pre.d
/etc/kdump/pre.d/50-foo.sh
/etc/kdump/pre.d/75-hoge.sh
Then, 50-foo.sh and 75-hoge.sh are executed in order before kdump dump process
begins just like kdump_pre directive written in /etc/kdump.conf.
This is composed of the following three patches created based on
commit 4b43ba063ddbcdccf95d761d2a3641f3006d814d.
