This reverts commit 19f869996f.
Leaving path info encoded confuses applications like Gitiles.
Trying to fix this inside of JGit was maybe the wrong solution.

Gitiles malfunctions in conjunction with jgit and guice
because of a recent Guice bug fix. Work around the problem
by parsing the URI directly, bypassing the unescaping
performed by the getPathInfo method.

This rest of this message is copied from
https://gerrit-review.googlesource.com/#/c/60820/ :

The fix for Guice issue #745[1] causes getPathInfo() within the
GuiceFilter to return decoded values, eliminating the difference
between "foo/bar" and "foo%2Fbar". This is in spec with the servlet
standard, whose javadoc for getPathInfo[2] states that the return
value be "decoded by the web container".

Work around this by extracting the path part directly from the request
URI, which is unmodified by the container. This is copying the Guice
behavior prior to the bugfix.

I have unfortunately introduced a few bugs in the native Git client
over the years. 1.7.5 is unable to send chunked requests correctly,
resulting in corrupt data at the server. Ban this client whenever
it uses chunked encoding with an error message.

Prior to some more recent versions, git push over HTTP failed to
report status information and error messages due to a race within
the client and its helper process. Check for these bad versions and
send errors as messages before the status report, enabling users
to see the failures on their terminal.

This never should have been in the core library test suite, as that
test suite never should depend upon the HTTP server module.

Some clients coming through proxies may advertise a different
Accept-Encoding, for example "Accept-Encoding: gzip(proxy)".
Matching by substring causes us to identify this as a false positive;
that the client understands gzip encoding and will inflate the
response before reading it.

In this particular case however it doesn't.  Its the reverse proxy
server in front of JGit letting us know the proxy<->JGit link can
be gzip compressed, while the client<->proxy part of the link is not:

  client <-- no gzip --> proxy <-- gzip --> JGit

Use a more standard method of parsing by splitting the value into
tokens, and only using gzip if one of the tokens is exactly the
string "gzip".  Add a unit test to make sure this isn't broken in
the future.
