Jakub Kulík 6f9bc72c79 bpo-35550: Fix incorrect Solaris define guards (GH-11275)
Python source code uses on several places ifdef sun or defined(sun) without the underscores, which is not standard compliant and shouldn't be used.

Defines should check for __sun instead. Reference: http://nadeausoftware.com/articles/2012/01/c_c_tip_how_use_compiler_predefined_macros_detect_operating_system#Solaris

BNMetrics b942707fc2 bpo-29341: Clarify that path-like objects are accepted in some os methods (GH-10101)
Some methods in the os module can accept path-like objects. This is documented in the general documentation but not in the function docstrings. To keep both in sync, the docstrings need to be updated to reflect that path-like objects are also accepted.

Alexey Izbyshev 834603112e bpo-32890, os: Use errno instead of GetLastError() in execve() and truncate() (GH-5784)
path_error() uses GetLastError() on Windows, but some os functions
are implemented via CRT APIs which report errors via errno.
This may result in raising OSError with invalid error code (such
as zero).

Introduce posix_path_error() function and use it where appropriate.

instead of raising ValueError or its subclasses UnicodeEncodeError
and UnicodeDecodeError for paths that contain characters or bytes
unrepresentative at the OS level.

bpo-34651: Only allow the main interpreter to fork. (gh-9279)
When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter.

bpo-34384: Fix os.readlink() on Windows (GH-8740)
os.readlink() now accepts path-like and bytes objects on Windows.
Previously, support for path-like and bytes objects was only
implemented on Unix.

This commit also merges Unix and Windows implementations of
os.readlink() in one function and adds basic unit tests to increase
test coverage of the function.

* Fix integer overflow in os.readv(), os.writev(), os.preadv()
  and os.pwritev() and in os.sendfile() with headers or trailers
  arguments (on BSD-based OSes and MacOS).

* Fix sending the part of the file in os.sendfile() on MacOS.
  Using the trailers argument could cause sending more bytes from
  the input file than was specified.

Thanks Ned Deily for testing on 32-bit MacOS.

regular or living on a network fs etc.) we better fail on open() instead
of copyfile(3) as we're not quite sure what's gonna happen in that
case.

os.dup2() tests for dup3() system call availability at runtime,

fix this by making the variable holding the test result static.
