Fix the regex to support the version 7.10: minor version with two digits

Patch by TAKASE Arihiro.

Fixed the case of the "Ctrl-" prefixes.

This changes the equivalent functions listed for the Base-64, hex and Quoted-
Printable codecs to reflect the functions actually used. Also mention and
test the "quotetabs" setting for Quoted-Printable encoding.

Most of these tests are about blacklisted non-text codecs, which are not
relevant in Python 2. The only one remaining is TransformCodecTest.test_uu_
invalid().

Reported by Nat Dunn on docs@

PyUnicode_AsEncodedString() instead of calling the encode() method of the
host, to handle correctly custom unicode string with an encode() method which
doesn't return a byte string. The encoder of the IDNA codec is now called
directly instead of calling the encode() method of the string.

Patch from Shiyao Ma.

It was very much outdated, and the topic is better covered elsewhere.

are supported by the filesystem.  On Windows the encoding can convert some
characters to '?' that is not legal in file name.

the path of the directory for temporary files contains symlinks.

It now better matches 3.5+ and the new reality of 2.7's PCbuild dir.

for directories (including empty directories) in ZIP file.
Added test for comparing shutil.make_archive() with the "zip" command.

Windows.  The test now makes sense on non-Windows.  Added similar test for
zip format.

in an infinite loop.  Patch by Xavier de Gaye.

Don't download sources that won't be used.

This modifies the behavior of the '-e' flag to PCbuild\build.bat: when '-e'
is not supplied, no attempt will be made to build extension modules that
require external libraries, even if the external libraries are present.

Also adds '--no-<module>' flags to PCbuild\build.bat, where '<module>' is
one of 'ssl', 'tkinter', or 'bsddb', to allow skipping just those modules
(if '-e' is given).

This makes it possible to pass more than 7 tests by name through
Tools\buildbot\test.bat

Don't check if importing a module emits a DeprecationWarning if the module is
implemented in C and the module is already loaded.

* Add py-bt-full command
* py-bt now gives an output similar to a regular Python traceback
* py-bt indicates:

  - if the garbage collector is running
  - if the thread is waiting for the GIL
  - detect PyCFunction_Call to get the name of the builtin function

Also fixes quoting to match 3.5+
