* bpo-29243: Fix Makefile with respect to --enable-optimizations
When using the Profile Guided Optimization (./configure --enable-optimizations)
Python is built not only during `make` but rebuilt again during `make test`,
`make install` and others. This patch fixes the issue.
Note that this fix produces no change at all in the Makefile if configure is
run witout --enable-optimizations.
* !squash
The reference to administrative data was confusing to readers,
so this simplifies the note to explain that deep copying may copy
more then you intended, such as data that you expected to be
shared between copies.
* change LBYL key lookup to dict.setdefault
The ``results`` was constructed as a defaultdict and we could simply
delete the check ``if key not in results``. However, I think it's safer
to use dict.setdefault as I'm not sure whether the caller expects a
regular dict or defaultdict.
* add name to the acknowledgements file
* use defaultdict to make the key-lookup cleaner
The Windows-specific subprocess.STARTUPINFO class now accepts
keyword-only arguments to its constructor to set the various
data attributes.

* bpo-16285: Update urllib quoting to RFC 3986
urllib.parse.quote is now based on RFC 3986, and hence
includes `'~'` in the set of characters that is not escaped
by default.
Patch by Christian Theune and Ratnadeep Debnath.
- Add 'preferred' argument to webbrowser.register
- Use xdg-settings to specify preferred X browser
The first change replaces the existing undocumented tri-state
'try_order' parameter with the documented boolean keyword-only
'preferred' parameter. Setting it to True places the browser at the
front of the list, preferring it as the return to a subsequent get() call.
The second change adds a private `_os_preferred_browser` setting
and then uses that to make the default browser reported by
`xdg-settings` first in the try list when running under X (or
another environment that sets the `DISPLAY` variable).
This avoids the problem where the first entry in the tryorder
queue otherwise defaults to xdg-open, which doesn't support
the "new window" option.
* Wrong parameter name, 'group_by' instead of 'key_type'
* Don't round up numbers when explaining the examples. If they exactly match
what can be read in the script output, it is to easier to understand
(4.8 MiB vs 4855 KiB)
* Fix incorrect method link that was pointing to another module
Patch written by Loic Pefferkorn.
