bpo-39406: Implement os.putenv() with setenv() if available (GH-18128)
If setenv() C function is available, os.putenv() is now implemented
with setenv() instead of putenv(), so Python doesn't have to handle
the environment variable memory.

bpo-39406: os.putenv() avoids putenv_dict on Windows (GH-18126)
Windows: _wputenv(env) copies the *env* string and doesn't require
the caller to manage the variable memory.

Move comment about permanent generation to gcmodule.c (GH-17718)

incorrectly referenced by a comment in gcmodule.c (the comment has been
moved long ago into a header file). Moving the comment into the relevant
code helps with readability and avoids broken references.

723f71abf7 bpo-37931: Fix crash on OSX re-initializing os.environ (GH-15428)
On most platforms, the `environ` symbol is accessible everywhere.

In a dylib on OSX, it's not easily accessible, you need to find it with
_NSGetEnviron.

The code was caching the *value* of environ. But a setenv() can change the value,
leaving garbage at the old value. Fix: don't cache the value of environ, just
read it every time.

7105319ada bpo-38634: Allow non-apple build to cope with libedit (GH-16986)
The readline module now detects if Python is linked to libedit at runtime
on all platforms.  Previously, the check was only done on macOS.

If Python is used as a library by a binary linking to libedit, the linker
resolves the rl_initialize symbol required by the readline module against
libedit instead of libreadline, which leads to a segfault.

Take advantage of the existing supporting code to have readline module being
compatible with both situations.

6f03b236c1 bpo-38876: Raise pickle.UnpicklingError when loading an item from memo for invalid input (GH-17335)
The previous code was raising a `KeyError` for both the Python and C implementation.
This was caused by the specified index of an invalid input which did not exist
in the memo structure, where the pickle stores what objects it has seen.
The malformed input would have caused either a `BINGET` or `LONG_BINGET` load
from the memo, leading to a `KeyError` as the determined index was bogus.

closes bpo-38712: Add signal.pidfd_send_signal. (GH-17070)
This exposes a Linux-specific syscall for sending a signal to a process
identified by a file descriptor rather than a pid.

For simplicity, we don't support the siginfo_t parameter to the syscall. This
parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which
Python also doesn't support.
