allow building against uninstalled guile; move some things to meta/

* README: Add more info about building against an uninstalled Guile.

* meta/: New directory. The proximate cause of its creation is that I
  want to be able to build external packages against uninstalled Guile,
  and to do that I need guile-tools in the PATH, but I don't want
  $top_builddir/libtool in the path. But it seems like a good
  reorganization, for things that are /about/ Guile: pkg-config files, m4
  files, guile-config... then we also include uninstalled info: the
  environment, the pre-inst-guile script, etc.

* meta/guile-1.8-uninstalled.pc.in: New pkg-config template. pkg-config
  prefers -uninstalled pkg-config files, if they are in its path.

* meta/Makefile.am:
* meta/ChangeLog-2008:
* meta/gdb-uninstalled-guile.in:
* meta/guile-1.8.pc.in:
* meta/guile-config.in:
* meta/guile.m4:
* meta/guile-tools.in: Moved to meta/.

* meta/guile.in: This is the new name of pre-inst-guile.in.

* meta/uninstalled-env.in: And this, pre-inst-guile-env.in.

* Makefile.am:
* am/guilec:
* am/pre-inst-guile:
* check-guile.in:
* configure.in:
* doc/ref/Makefile.am:
* gc-benchmarks/run-benchmark.scm:
* test-suite/standalone/Makefile.am:
* test-suite/standalone/README:
* testsuite/Makefile.am: Adapt to meta/ change.

+# Commentary:
+
+# Usage: guile [ARGS]
+#
+# This script arranges for the environment to support, and eventaully execs,
+# the uninstalled binary guile executable located somewhere under libguile/,
+# passing ARGS to it.  In the process, env var GUILE is clobbered, and the
+# following env vars are modified (but not clobbered):
+#   GUILE_LOAD_PATH
+#   LTDL_LIBRARY_PATH
+#
+# This script can be used as a drop-in replacement for $bindir/guile;
+# if there is a discrepency in behavior, that's a bug.
+
+# Code:
+
+# env (set by configure)
+top_builddir="@top_builddir_absolute@"
+
+# set GUILE (clobber)
+GUILE=${top_builddir}/libguile/guile
+export GUILE
+
+# do it
+exec ${top_builddir}/meta/uninstalled-env $GUILE "$@"
+
+# never reached
+exit 1
+
+# guile ends here
