configure: add support for "config.gypi" and "commong.gypi" files

When present alongside the "binding.gyp" file. This gives addons a chance to
overwrite default variables specified in the gyp files of the native addon's
gyp dependencies.
configure: remove trailing semicolons
v0.8.0
legacy: remove "tools" dir

Presumably everything that was in here is now being bundled directly by
node-gyp...
add gyp https://codereview.chromium.org/11368059
install: don't extract the "gyp" dir from the node tarball
configure: run the bundled gyp rather than the one from the tarball
gyp: always install into $PRODUCT_DIR
gyp: apply https://codereview.chromium.org/11361103/

v0.8.2
addon.gypi: define _LARGEFILE_SOURCE, _FILE_OFFSET_BITS

Since as of joyent/node@83e5e20c2c24f440b9212453336e7495402a9ed8, these are no
longer defined in node's commong.gypi file, so we need to define them here as
well.
