The fs.readFile bug was hiding another bug that was causing this test
to pass, even so it was broken:

require.async("../fixtures/throws_error1") in test-module-loading.js

This patch fixes the original test by running _compile within a
try..catch block for _loadScript.

_loadScriptSync also had some useless (deprecated?) code for dealing
with module entry point exceptions. This code was also removed for
greater clarity.

fs.readFile was executing a callback in a try..catch context, which is
a problem in itself. To make matters worse, it would re-execute the
same callback if there was an execution.

This patch fixes both of these problems.

ref: <http://github.com/ry/node/issues#issue/153>

a) create a layer of indirection in net.Stream to allow swapping in
different read/write implementations and

b) emit an 'fd' event when file descriptors are received over a UNIX pipe,
as finally as a tangential benefit

c) remove a bunch of conditionals from the primary codepaths for
ease-of-reading.

Removes 'make all-debug' since it is unnecessary now.

After the child is forked, these file descriptors will get dup2()'d to STDIN,
STDIO, and STDERR.

(API may be changed.)

Broke the build. Will fix and reapply soon.

This reverts commit 75f0cf47.

This adds the following options to the `configure` program

  --shared-v8           Link to a shared V8 DLL instead of static linking
  --shared-v8-includes=SHARED_V8_INCLUDES
                        Directory containing V8 header files
  --shared-v8-libpath=SHARED_V8_LIBPATH
                        A directory to search for the shared V8 DLL
  --shared-cares        Link to a shared C-Ares DLL instead of static linking
  --shared-cares-includes=SHARED_CARES_INCLUDES
                        Directory containing C-Ares header files
  --shared-cares-libpath=SHARED_CARES_LIBPATH
                        A directory to search for the shared C-Ares DLL
  --shared-libev        Link to a shared libev DLL instead of static linking
  --shared-libev-includes=SHARED_LIBEV_INCLUDES
                        Directory containing libev header files
  --shared-libev-libpath=SHARED_LIBEV_LIBPATH
                        A directory to search for the shared libev DLL

and removes --system.

Correctly load utf8 data; add a test test-fs-read-file-sync.js

This makes it so that inspecting objects from other contexts works as expected.

Don't treat sys.inspect special, same with prototype objects.

Allow throttling from outgoing messages.

Improve test-fs-read-stream test.

Patch submitted to V8: http://codereview.chromium.org/2282003/show

Notes:
- Currently only accepts numeric user and group ids.
- No tests, as tests depend on getpwuid and getgrgid.
- No documentation, as there is no tests and this is experimental.

And do proper utf8 encoding.
