perldelta: remove sections we will not need
perlhist: import the latest perlhist from blead
version bump, because Digest::SHA changed
import Module-Corelist 2.95 from blead
update corelist with v5.18.1 changes

I am not following the instructions in the RMG, because the
procedure is sort of a mess.  I will make sure that blead gets into
the right state when this is done.  In the meantime, doing it this
way should require less weird moving of work back and forth.
bump version to v5.18.1-RC1
Update META.json for RC1
Revert "update corelist with v5.18.1 changes"

import updates to Porting/corelist.pl
update corelist with v5.18.1 changes

...again.  This time, using the updated updater, fixing the
deprecations screwed up in 5.18.1 RC1.
perldelta: fix module updates section
perldelta: remove a leftover XXX section
RT #119125: continue /[#$x]/x not interpolating

the earlier fix for /[#](?{})/x, although correct, as a
side-effect fixed another long-standing bug where /[#$x]/x
didn't interpolate the var $x. Although fixing that is good,
it's too big a change for maint, so keep the old buggy behaviour
for now.
perlhist: add 5.18.1!

perldelta: mention v5.16, not v5.17, as previous version

Thanks for the report, SHIRAKATA Kentaro.
The language messages variable is called LC_MESSAGES

This probably doesn't matter as LC_ALL overrides everything else.
