* bpo-31044: Skip test_posix.test_makedev() on FreeBSD (#2915)
There is a bug in FreeBSD CURRENT with 64-bit dev_t. Skip the test if
dev_t is larger than 32-bit, until the bug is fixed in FreeBSD
CURRENT.
(cherry picked from commit 12953ffe12)
* Fix syntax for Python 2.7
* bpo-31028: Fix test_pydoc when run directly
Fix get_pydoc_link() of test_pydoc to fix "./python
Lib/test/test_pydoc.py": get the absolute path to __file__ to prevent
relative directories.
* Use realpath() instead of abspath()
(cherry picked from commit fd46561167)
* bpo-30980: Fix close test to fail
test_close_twice was not considering the fact that file_wrapper is
duping the file descriptor. Closing the original descriptor left the
duped one open, hiding the fact that close protection is not effective.
* bpo-30980: Fix double close protection
Invalidated self.fd before closing, handling correctly the case when
os.close raises.
* bpo-30980: Fix fd leak introduced in the fixed test
multiprocessing.Process.is_alive() now removes the process from the
_children set if the process completed.
The change prevents leaking "dangling" processes.

* bpo-30595: Fix multiprocessing.Queue.get(timeout) (#2027)
multiprocessing.Queue.get() with a timeout now polls its reader in
non-blocking mode if it succeeded to aquire the lock but the acquire
took longer than the timeout.

* bpo-30595: Increase test_queue_feeder_donot_stop_onexc() timeout (#2148)
_test_multiprocessing.test_queue_feeder_donot_stop_onexc() now uses a
timeout of 1 second on Queue.get(), instead of 0.1 second, for slow
buildbots.

bpo-30850: On Windows, test04_lock_timeout2() now tolerates 50 ms
whereas 100 ms is expected. The lock sometimes times out after only
58 ms. Windows clocks have a bad resolution and bad accuracy.
Adds a new 'Pip not installed' section that covers
running `ensurepip` manually, and also references
the relevant section of the Python Packaging User
Guide.
(cherry picked from commit b3527bfefd)
If history-length is set in .inputrc, and the history file is double the
history size (or more), history_get(N) returns NULL, and python
segfaults. Fix that by checking for NULL return value.
It seems that the root cause is incorrect handling of bigger history in
readline, but Python should not segfault even if readline returns
unexpected value.
This issue affects only GNU readline. When using libedit emulation
system history size option does not work.
This is a backport of the actual fix from master without the test, since
the test depends on new run_pty() helper which is not available in 2.7.
