From 6ccf33cdbdfda2aea5d51e4d4991881c74d853d1 Mon Sep 17 00:00:00 2001

Subject: This is a major update, which switches virtually every
 allocated-but-not-freed string into the strcache.  As a side-effect, many
 more structure members and function arguments can/should be declared const.

As mentioned in the changelog, unfortunately measurement shows that this
change does not yet reduce memory.  The problem is with secondary expansion:
because of this we store all the prerequisites in the string cache twice.
First we store the prerequisite string after initial expansion but before
secondary expansion, then we store each individual file after secondary
expansion and expand_deps().  I plan to change expand_deps() to be callable
in either context (eval or snap_deps) then have non-second-expansion
targets call expand_deps() during eval, so that we only need to store that
dependency list once.
