The http/ and hashtable/ Makefiles named sources that do not exist
(test.c, net.c, net.h in http/; http.h in hashtable/) and had no way to
find the sibling hashtable/llist sources they link against, so neither
directory built at all. Both now compile those sources with explicit
recipes.
VPATH would be the terser fix but is deliberately avoided: it searches
for targets as well as sources, so a stale ../llist/test.o gets linked
in place of a freshly compiled one, and hashtable/test silently runs the
linked-list suite instead of its own.
llist/Makefile built fine; its .PHONY read "all," with a comma, making
that the literal target name, and test.o was missing its llist.h
dependency.
README covers layout, build, run, the use()/Handler routing API, and the
library tests.
