Decouple BouncyCastle from JGit Core

Motivation: BouncyCastle serves as 'default' implementation of
the GPG Signer. If a client application does not use it there is no need
to pull in this dependency, especially since BouncyCastle is a large
library.

Move the classes depending on BouncyCastle to an OSGi fragment extending
the org.eclipse.jgit bundle. They are moved to a distinct internal
package in order to avoid split packages. This doesn't break public API
since these classes were already in an internal package before this
change.

Add a new feature org.eclipse.jgit.gpg.bc to enable installation. With
that users can now decide if they want to install it.

Attempts to sign a commit if org.eclipse.jgit.gpg.bc isn't available
will result in ServiceUnavailableException being thrown.

+AGREEMENTS OR NOTICES INDICATED OR REFERENCED BELOW. IF YOU DO NOT AGREE TO THE\n\
+TERMS AND CONDITIONS OF THIS AGREEMENT AND THE TERMS AND CONDITIONS OF ANY\n\
+APPLICABLE LICENSE AGREEMENTS OR NOTICES INDICATED OR REFERENCED BELOW, THEN YOU\n\
+MAY NOT USE THE CONTENT.\n\
+\n\
+Applicable Licenses\n\
+\n\
+Unless otherwise indicated, all Content made available by the Eclipse Foundation\n\
+is provided to you under the terms and conditions of the Eclipse Public License\n\
+Version 2.0 ("EPL"). A copy of the EPL is provided with this Content and is also\n\
+available at http://www.eclipse.org/legal/epl-2.0. For purposes of the EPL,\n\
+"Program" will mean the Content.\n\
+\n\
+Content includes, but is not limited to, source code, object code, documentation\n\
+and other files maintained in the Eclipse Foundation source code repository\n\
+("Repository") in software modules ("Modules") and made available as\n\
+downloadable archives ("Downloads").\n\
+\n\
+-   Content may be structured and packaged into modules to facilitate\n\
+    delivering, extending, and upgrading the Content. Typical modules may\n\
+    include plug-ins ("Plug-ins"), plug-in fragments ("Fragments"), and\n\
+    features ("Features").\n\
+-   Each Plug-in or Fragment may be packaged as a sub-directory or JAR\n\
+    (Java\u2122 ARchive) in a directory named "plugins".\n\
+-   A Feature is a bundle of one or more Plug-ins and/or Fragments and\n\
+    associated material. Each Feature may be packaged as a sub-directory in a\n\
+    directory named "features". Within a Feature, files named "feature.xml" may\n\
+    contain a list of the names and version numbers of the Plug-ins and/or\n\
+    Fragments associated with that Feature.\n\
+-   Features may also include other Features ("Included Features"). Within a\n\
+    Feature, files named "feature.xml" may contain a list of the names and\n\
+    version numbers of Included Features.\n\
+\n\
+The terms and conditions governing Plug-ins and Fragments should be contained in\n\
+files named "about.html" ("Abouts"). The terms and conditions governing Features\n\
+and Included Features should be contained in files named "license.html"\n\
+("Feature Licenses"). Abouts and Feature Licenses may be located in any\n\
+directory of a Download or Module including, but not limited to the following\n\
+locations:\n\
+\n\
+-   The top-level (root) directory\n\
+-   Plug-in and Fragment directories\n\
+-   Inside Plug-ins and Fragments packaged as JARs\n\
+-   Sub-directories of the directory named "src" of certain Plug-ins\n\
+-   Feature directories\n\
+\n\
+Note: if a Feature made available by the Eclipse Foundation is installed using\n\
+the Provisioning Technology (as defined below), you must agree to a license\n\
+("Feature Update License") during the installation process. If the Feature\n\
+contains Included Features, the Feature Update License should either provide you\n\
+with the terms and conditions governing the Included Features or inform you\n\
+where you can locate them. Feature Update Licenses may be found in the "license"\n\
+property of files named "feature.properties" found within a Feature. Such\n\
+Abouts, Feature Licenses, and Feature Update Licenses contain the terms and\n\
+conditions (or references to such terms and conditions) that govern your use of\n\
+the associated Content in that directory.\n\
+\n\
+THE ABOUTS, FEATURE LICENSES, AND FEATURE UPDATE LICENSES MAY REFER TO THE EPL\n\
+OR OTHER LICENSE AGREEMENTS, NOTICES OR TERMS AND CONDITIONS. SOME OF THESE\n\
+OTHER LICENSE AGREEMENTS MAY INCLUDE (BUT ARE NOT LIMITED TO):\n\
+\n\

+\n\
+Use of Provisioning Technology\n\
+\n\
+The Eclipse Foundation makes available provisioning software, examples of which\n\
+include, but are not limited to, p2 and the Eclipse Update Manager\n\
+("Provisioning Technology") for the purpose of allowing users to install\n\
+software, documentation, information and/or other materials (collectively\n\
+"Installable Software"). This capability is provided with the intent of allowing\n\
+such users to install, extend and update Eclipse-based products. Information\n\
+about packaging Installable Software is available at\n\
+http://eclipse.org/equinox/p2/repository_packaging.html ("Specification").\n\
+\n\
+You may use Provisioning Technology to allow other parties to install\n\
+Installable Software. You shall be responsible for enabling the applicable\n\
+license agreements relating to the Installable Software to be presented to, and\n\
+accepted by, the users of the Provisioning Technology in accordance with the\n\
+Specification. By using Provisioning Technology in such a manner and making it\n\
+available in accordance with the Specification, you further acknowledge your\n\
+agreement to, and the acquisition of all necessary rights to permit the\n\
+following:\n\
+\n\
+1.  A series of actions may occur ("Provisioning Process") in which a user may\n\
+    execute the Provisioning Technology on a machine ("Target Machine") with the\n\
+    intent of installing, extending or updating the functionality of an\n\
+    Eclipse-based product.\n\
+2.  During the Provisioning Process, the Provisioning Technology may cause third\n\
+    party Installable Software or a portion thereof to be accessed and copied to\n\
+    the Target Machine.\n\
+3.  Pursuant to the Specification, you will provide to the user the terms and\n\
+    conditions that govern the use of the Installable Software ("Installable\n\
+    Software Agreement") and such Installable Software Agreement shall be\n\
+    accessed from the Target Machine in accordance with the Specification. Such\n\
+    Installable Software Agreement must inform the user of the terms and\n\
+    conditions that govern the Installable Software and must solicit acceptance\n\
+    by the end user in the manner prescribed in such Installable\n\
+    Software Agreement. Upon such indication of agreement by the user, the\n\
+    provisioning Technology will complete installation of the\n\
+    Installable Software.\n\
+\n\
+Cryptography\n\
+\n\
+Content may contain encryption software. The country in which you are currently\n\
+may have restrictions on the import, possession, and use, and/or re-export to\n\
+another country, of encryption software. BEFORE using any encryption software,\n\
+please check the country's laws, regulations and policies concerning the import,\n\
+possession, or use, and re-export of encryption software, to see if this is\n\

+		the Feature Update License should either provide you with the terms
+		and conditions governing the Included Features or inform you where you
+		can locate them. Feature Update Licenses may be found in the
+		&quot;license&quot; property of files named
+		&quot;feature.properties&quot; found within a Feature. Such Abouts,
+		Feature Licenses, and Feature Update Licenses contain the terms and
+		conditions (or references to such terms and conditions) that govern
+		your use of the associated Content in that directory.</p>
+	<p>THE ABOUTS, FEATURE LICENSES, AND FEATURE UPDATE LICENSES MAY
+		REFER TO THE EPL OR OTHER LICENSE AGREEMENTS, NOTICES OR TERMS AND

+	<h3>Use of Provisioning Technology</h3>
+	<p>
+		The Eclipse Foundation makes available provisioning software, examples
+		of which include, but are not limited to, p2 and the Eclipse Update
+		Manager (&quot;Provisioning Technology&quot;) for the purpose of
+		allowing users to install software, documentation, information and/or
+		other materials (collectively &quot;Installable Software&quot;). This
+		capability is provided with the intent of allowing such users to
+		install, extend and update Eclipse-based products. Information about
+		packaging Installable Software is available at <a
+			href="http://eclipse.org/equinox/p2/repository_packaging.html">http://eclipse.org/equinox/p2/repository_packaging.html</a>
+		(&quot;Specification&quot;).
+	</p>
+	<p>You may use Provisioning Technology to allow other parties to
+		install Installable Software. You shall be responsible for enabling
+		the applicable license agreements relating to the Installable Software
+		to be presented to, and accepted by, the users of the Provisioning
+		Technology in accordance with the Specification. By using Provisioning
+		Technology in such a manner and making it available in accordance with
+		the Specification, you further acknowledge your agreement to, and the
+		acquisition of all necessary rights to permit the following:</p>
+	<ol>
+		<li>A series of actions may occur (&quot;Provisioning
+			Process&quot;) in which a user may execute the Provisioning
+			Technology on a machine (&quot;Target Machine&quot;) with the intent
+			of installing, extending or updating the functionality of an
+			Eclipse-based product.</li>
+		<li>During the Provisioning Process, the Provisioning Technology
+			may cause third party Installable Software or a portion thereof to be
+			accessed and copied to the Target Machine.</li>
+		<li>Pursuant to the Specification, you will provide to the user
+			the terms and conditions that govern the use of the Installable
+			Software (&quot;Installable Software Agreement&quot;) and such
+			Installable Software Agreement shall be accessed from the Target
+			Machine in accordance with the Specification. Such Installable
+			Software Agreement must inform the user of the terms and conditions
+			that govern the Installable Software and must solicit acceptance by
+			the end user in the manner prescribed in such Installable Software
+			Agreement. Upon such indication of agreement by the user, the
+			provisioning Technology will complete installation of the Installable
+			Software.</li>
+	</ol>
