Fix SUBMITTING_PATCHES to follow the Eclipse IP process

I somehow missed that SUBMITTING_PATCHES referenced the older "send
to git mailing list by email" patch process we used for the first
few years of the JGit project's life.  Now that we are hosted under
the Eclipse Foundation umbrella we need to follow their IP process
for all contributions.

-It is a common convention to prefix your subject line with [PATCH].
-This lets people easily distinguish patches from other e-mail
-discussions.
-
-"git format-patch" command follows the best current practice to
-format the body of an e-mail message.  At the beginning of the patch
-should come your commit message, ending with the Signed-off-by:
-lines, and a line that consists of three dashes, followed by the
-diffstat information and the patch itself.  If you are forwarding a
-patch from somebody else, optionally, at the beginning of the e-mail
-message just before the commit message starts, you can put a "From:
-" line to name that person.

-You often want to add additional explanation about the patch,
-other than the commit message itself.  Place such "cover letter"

-
-Do not attach the patch as a MIME attachment, compressed or not.
-Do not let your e-mail client send quoted-printable.  Do not let your
-e-mail client send format=flowed which would destroy whitespaces
-in your patches. Many popular e-mail applications will not always
-transmit a MIME attachment as plain text, making it impossible to
-comment on your code.  A MIME attachment also takes a bit more
-time to process.  This does not decrease the likelihood of your
-MIME-attached change being accepted, but it makes it more likely
-that it will be postponed.
-
-Exception:  If your mailer is mangling patches then someone may ask
-you to re-send them using MIME, that is OK.
-
-Do not PGP sign your patch, at least for now.  Most likely, your
-maintainer or other people on the list would not have your PGP
-key and would not bother obtaining it anyway.  Your patch is not
-judged by who you are; a good patch from an unknown origin has a
-far better chance of being accepted than a patch from a known,
-respected origin that is done poorly or does incorrect things.
-
-If you really really really really want to do a PGP signed
-patch, format it as "multipart/signed", not a text/plain message
-that starts with '-----BEGIN PGP SIGNED MESSAGE-----'.  That is
-not a text/plain, it's something else.
-
-Note that your maintainer does not necessarily read everything
-on the git mailing list.  If your patch is for discussion first,

-(5) Sign your work
-
-To improve tracking of who did what, we've borrowed the "sign-off"
-procedure from the Linux kernel project on patches that are being
-emailed around.  Although JGit is a lot smaller project it is
-a good discipline to follow it.
-
-The sign-off is a simple line at the end of the explanation for the
-patch, which certifies that you wrote it or otherwise have the right
-to pass it on as a open-source patch.  The rules are pretty simple:
-if you can certify the below:
-
-        Developer's Certificate of Origin 1.1
-
-        By making a contribution to this project, I certify that:
-
-        (a) The contribution was created in whole or in part by me
-            and I have the right to submit it under the open source
-            license indicated in the file; or
-
-        (b) The contribution is based upon previous work that, to the
-            best of my knowledge, is covered under an appropriate
-            open source license and I have the right under that
-            license to submit that work with modifications, whether
-            created in whole or in part by me, under the same open
-            source license (unless I am permitted to submit under
-            a different license), as indicated in the file; or
-
-        (c) The contribution was provided directly to me by some
-            other person who certified (a), (b) or (c) and I have
-            not modified it.
-
-        (d) I understand and agree that this project and the
-            contribution are public and that a record of the
-            contribution (including all personal information I
-            submit with it, including my sign-off) is maintained
-            indefinitely and may be redistributed consistent with
-            this project or the open source license(s) involved.
-
-then you just add a line saying
-
-    Signed-off-by: Random J Developer <random@developer.example.org>
-
-This line can be automatically added by git if you run the git-commit
-command with the -s option.
-
-Some people also put extra tags at the end.  They'll just be ignored
-for now, but you can do this to mark internal company procedures
-or just point out some special detail about the sign-off.

-------------------------------------------------
-MUA specific hints
-
-Some of patches I receive or pick up from the list share common
-patterns of breakage.  Please make sure your MUA is set up
-properly not to corrupt whitespaces.  Here are two common ones
-I have seen:
-
-* Empty context lines that do not have _any_ whitespace.
-
-* Non empty context lines that have one extra whitespace at the
-  beginning.
-
-One test you could do yourself if your MUA is set up correctly is:
-
-* Send the patch to yourself, exactly the way you would, except
-  To: and Cc: lines, which would not contain the list and
-  maintainer address.
-
-* Save that patch to a file in UNIX mailbox format.  Call it say
-  a.patch.
+(4) Review the Eclipse Due Diligence Process.
 
-* Try to apply to the tip of the "master" branch from the
-  egit.git public repository:
+  http://www.eclipse.org/legal/EclipseLegalProcessPoster.pdf
 
-    $ git fetch git://repo.or.cz/egit.git master:test-apply
-    $ git checkout test-apply
-    $ git reset --hard
-    $ git am a.patch
 
-If it does not apply correctly, there can be various reasons.
+(5) Sending your patches.
 
-* Your patch itself does not apply cleanly.  That is _bad_ but
-  does not have much to do with your MUA.  Please rebase the
-  patch appropriately.
-
-* Your MUA corrupted your patch; applymbox would complain that
-  the patch does not apply.  Look at .dotest/ subdirectory and
-  see what 'patch' file contains and check for the common
-  corruption patterns mentioned above.
-
-* While you are at it, check what are in 'info' and
-  'final-commit' files as well.  If what is in 'final-commit' is
-  not exactly what you would want to see in the commit log
-  message, it is very likely that your maintainer would end up
-  hand editing the log message when he applies your patch.
-  Things like "Hi, this is my first patch.\n", if you really
-  want to put in the patch e-mail, should come after the
-  three-dash line that signals the end of the commit message.

-Ah, it looks like a recent version changed the default behavior to do the
-right thing, and inverted the sense of the configuration option. (Either
-that or Gentoo did it.) So you need to set the
-"no-strip-whitespace-before-send" option, unless the option you have is
-"strip-whitespace-before-send", in which case you should avoid checking
-it.

-Thunderbird
------------
-
-(A Large Angry SCM)
-
-Here are some hints on how to successfully submit patches inline using
-Thunderbird.
-
-This recipe appears to work with the current [*1*] Thunderbird from Suse.
-
-The following Thunderbird extensions are needed:
-	AboutConfig 0.5
-		http://aboutconfig.mozdev.org/
-	External Editor 0.7.2
-		http://globs.org/articles.php?lng=en&pg=8
-
-1) Prepare the patch as a text file using your method of choice.
-
-2) Before opening a compose window, use Edit->Account Settings to
-uncheck the "Compose messages in HTML format" setting in the
-"Composition & Addressing" panel of the account to be used to send the
-patch. [*2*]
-
-3) In the main Thunderbird window, _before_ you open the compose window
-for the patch, use Tools->about:config to set the following to the
-indicated values:
-	mailnews.send_plaintext_flowed	=> false
-	mailnews.wraplength		=> 0
-
-4) Open a compose window and click the external editor icon.
-
-5) In the external editor window, read in the patch file and exit the
-editor normally.
-
-6) Back in the compose window: Add whatever other text you wish to the
-message, complete the addressing and subject fields, and press send.
-
-7) Optionally, undo the about:config/account settings changes made in
-steps 2 & 3.

-'|' in the *Summary* buffer can be used to pipe the current
-message to an external program, and this is a handy way to drive
-"git am".  However, if the message is MIME encoded, what is
-piped into the program is the representation you see in your
-*Article* buffer after unwrapping MIME.  This is often not what
-you would want for two reasons.  It tends to screw up non ASCII
-characters (most notably in people's names), and also
-whitespaces (fatal in patches).  Running 'C-u g' to display the
-message in raw form before using '|' to run the pipe can work
-this problem around.
