dev-python/pyzor: new revision to fix some open bugs.

Lots of changes all at once:

* Update to EAPI=6.
* Remove an old pkg_postinst() notice about a relocated executable.
* Add IUSE=gdbm to make the gdbm daemon backend optional.
* Only require a (gdbm, mysql, redis) backend with USE=pyzord.
* Add a patch submitted upstream (by me) to fix a unicode crash.
* Require sphinx with USE=doc (bug 636752).
* Remove version constraints on redis-py and gevent (bug 643692).
* Use HOMEPAGE to make SRC_URI fit on one line.
* Add die() to "mv" and "rm" commands in src_install.
* Removed seemingly-unnecessary DISTUTILS_IN_SOURCE_BUILD=1.
* Added myself to metadata.xml as a maintainer.
* Improved the back-end database engine USE flag descriptions.

+Subject: [PATCH 1/1] scripts/pyzor: read stdin as binary in _get_input_msg().
+
+Reading stdin in python-3.x is done as text, with a best-guess
+encoding. But this can go awry: for example, if an iso-8859-1 message
+is passed in and if python guesses the "utf-8" encoding, then read()
+will fail with a UnicodeDecodeError on non-ASCII characters. For
+example, the "copyright" symbol is a single byte 0xa9 in iso-8859-1,
+and the utf-8 decoder can't handle it:
+
+  UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa9... invalid
+  start byte
+
+Instead -- and as was done in python-2.x -- we can read stdin as
+binary using the new get_binary_stdin() function. Afterwards, we use
+email.message_from_bytes() instead of the email.message_from_file()
+constructor to parse the byte data. The resulting function is able to
+correctly parse these messages.
+
