Remove dependence on Aegis symlinks by adding a bootstrap.py script (suggested by Anthony Roach) to collect the current SCons into a bootstrap/ subdirectory for execution.

+"""bootstrap.py
+
+This is an Aegis-to-SCons build script that collects a copy of the
+current SCons into a bootstrap/ subdirectory and then executes it with
+the supplied command-line options.
+
+Right now, it only understands the SCons -Y option, which is the only
+one currently used. It collects the repositories specified by -Y and
+searches them, in order, for the pieces of SCons to copy into the local
+bootstrap/ subdirectory.
+
+This is essentially a minimal build of SCons to bootstrap ourselves into
+executing it for the full build of all the packages, as specified in our
+local SConstruct file.
