When a https connection could not be established because the SSL
handshake was unsuccessful, TransportHttp would unconditionally
throw a TransportException.
Other https clients like web browsers or also some SVN clients
handle this more gracefully. If there's a problem with the server
certificate, they inform the user and give him a possibility to
connect to the server all the same.
In git, this would correspond to dynamically setting http.sslVerify
to false for the server.
Implement this using the CredentialsProvider to inform and ask the
user. We offer three choices:
1. skip SSL verification for the current git operation, or
2. skip SSL verification for the server always from now on for
requests originating from the current repository, or
3. always skip SSL verification for the server from now on.
For (1), we just suppress SSL verification for the current instance of
TransportHttp.
For (2), we store a http.<uri>.sslVerify = false setting for the
original URI in the repo config.
For (3), we store the http.<uri>.sslVerify setting in the git user
config.
Adapt the SmartClientSmartServerSslTest such that it uses this
mechanism instead of setting http.sslVerify up front.
Improve SimpleHttpServer to enable setting it up also with HTTPS
support in anticipation of an EGit SWTbot UI test verifying that
cloning via HTTPS from a server that has a certificate that doesn't
validate pops up the correct dialog, and that cloning subsequently
proceeds successfully if the user decides to skip SSL verification.

Do not automatically organize imports using a save action since this
seems to be buggy and removed some annotations org.eclipse.jgit.pgm
needs to use args4j.

Revert the following save actions which were introduced in c0ad77d8:
- always use braces around blocks
- remove unused imports
Other than I expected save actions are run globally on edited files -
and not only on edited code lines only.
Hence revert the save action "Convert control statement bodies to
blocks" which would affect a large number of code lines not affected by
the change editing some small part of a class. This would generate a
large number of changes which may lead to many unnecessary conflicts.
Total number of affected lines across jgit would be around 10k lines.
Also revert "Remove unused imports" since it erroneously removes imports
of some annotations needed by pgm classes using args4j.

Add the following Eclipse save actions executed when saving modified
lines. This should help to reduce manual work needed to maintain a clean
and consistent code style:
- organize imports
- always use braces around blocks
- add missing annotations
- @Override including implementation of interface methods
- @Deprecated
- remove
- unused imports
- unnecessary $NON-NLS$ tags
- redundant type arguments
Also add default values for new settings that were introduced in recent
Eclipse versions up to Neon since we updated save rules the last time.

There is at least one git server out there (GOGS) that does
not require authentication on the initial GET for
info/refs?service=git-receive-pack but that _does_ require
authentication for the subsequent POST to actually do the push.
This occurs on GOGS with public repositories; for private
repositories it wants authentication up front.
Handle this behavior by adding 401 handling to our POST request.
Note that this is suboptimal; we'll re-send the push data at
least twice if an authentication failure on POST occurs. It
would be much better if the server required authentication
up-front in the GET request.
Added authentication unit tests (using BASIC auth) to the
SmartClientSmartServerTest:
- clone with authentication
- clone with authentication but lacking CredentialsProvider
- clone with authentication and wrong password
- clone with authentication after redirect
- clone with authentication only on POST, but not on GET
Also tested manually in the wild using repositories at try.gogs.io.
That server offers only BASIC auth, so the other paths
(DIGEST, NEGOTIATE, fall back from DIGEST to BASIC) are untested
and I have no way to test them.
* public repository: GET unauthenticated, POST authenticated
Also tested after clearing the credentials and then entering a
wrong password: correctly asks three times during the HTTP
POST for user name and password, then gives up.
* private repository: authentication already on GET; then gets
applied correctly initially to the POST request, which succeeds.
Also fix the authentication to use the credentials for the redirected
URI if redirects had occurred. We must not present the credentials
for the original URI in that case. Consider a malicious redirect A->B:
this would allow server B to harvest the user credentials for server
A. The unit test for authentication after a redirect also tests for
this.

git-core follows HTTP redirects so JGit should also provide this.
Implement config setting http.followRedirects with possible values
"false" (= never), "true" (= always), and "initial" (only on GET, but
not on POST).[1]
We must do our own redirect handling and cannot rely on the support
that the underlying real connection may offer. At least the JDK's
HttpURLConnection has two features that get in the way:
* it does not allow cross-protocol redirects and thus fails on
http->https redirects (for instance, on Github).
* it translates a redirect after a POST to a GET unless the system
property "http.strictPostRedirect" is set to true. We don't want
to manipulate that system setting nor require it.
Additionally, git has its own rules about what redirects it accepts;[2]
for instance, it does not allow a redirect that adds query arguments.
We handle response codes 301, 302, 303, and 307 as per RFC 2616.[3]
On POST we do not handle 303, and we follow redirects only if
http.followRedirects == true.
Redirects are followed only a certain number of times. There are two
ways to control that limit:
* by default, the limit is given by the http.maxRedirects system
property that is also used by the JDK. If the system property is
not set, the default is 5. (This is much lower than the JDK default
of 20, but I don't see the value of following so many redirects.)
* this can be overwritten by a http.maxRedirects git config setting.
The JGit http.* git config settings are currently all global; JGit has
no support yet for URI-specific settings "http.<pattern>.name". Adding
support for that is well beyond the scope of this change.
Like git-core, we log every redirect attempt (LOG.info) so that users
may know about the redirection having occurred.
Extends the test framework to configure an AppServer with HTTPS support
so that we can test cloning via HTTPS and redirections involving HTTPS.
