1e01a74445 Port _FileDescriptorStreamsNonBlocking to use poll()
select() has a limit of FD_SETSIZE file descriptors. If you run repo
sync -j500 you'll pretty quickly hit this limit and get "file descriptor
out of range for select" errors. poll() has no such limit.

f454512619 sync: make .git init more robust
Hitting Ctrl-C in the middle of this func will leave the .git in a
bad state that requires manual recovery.  The code tries to catch
all exceptions and recover by deleting the incomplete .git dir, but
it omits KeyboardInterrupt which Exception misses.

We could add that to the recovery path, but we can make this more
robust with a different approach: set up everything in .git.tmp/
and only move it to .git/ once we've fully initialized it.

f601376e13 set default file encoding to utf-8
There's no reason to support any other encoding in these files.
This only affects the files themselves and not streams they open.

bed8b62345 Add support for long paths
* Add more file i/o wrappers in platform_utils to allow using
  long paths (length > MAX_PATH) on Windows.

* Paths using the long path syntax ("\\?\" prefix) should never
  escape the platform_utils API surface area, so that this
  specific syntax is not visible to the rest of the repo code base.

* Forward many calls from os.xxx to platform_utils.xxx in various place
  to ensure long paths support, specifically when repo decides to delete
  obsolete directories.

* There are more places that need to be converted to support long paths,
  this commit is an initial effort to unblock a few common use cases.

* Also, fix remove function to handle directory symlinks

010fed7711 Replace all os.remove calls
os.remove raises an exception when deleting read-only files on
Windows. Replace all calls with calls to platform_utils.remove,
which deals with deals with that issue.

ad1abcb556 Port os.rename calls to work on Windows
os.rename fails on Windows if the destination exists, so replace
os.rename to platform_utils.rename which handles the platform
differences.

a65adf74f9 Workaround shutil.rmtree limitation on Windows
By default, shutil.rmtree raises an exception when deleting readonly
files on Windows.

Replace all shutil.rmtree with platform_utils.rmtree, which adds an
error handler to make files read-write when they can't be deleted.

d5cec5e752 Add support for creating symbolic links on Windows
Replace all calls to os.symlink with platform_utils.symlink.

The Windows implementation calls into the CreateSymbolicLinkW Win32
API, as os.symlink is not supported.

Separate the Win32 API definitions into a separate module
platform_utils_win32 for clarity.

2e70291162 Make "git command" and "forall" work on Windows
Python on Windows does not support non blocking file operations.
To workaround this issue, we instead use Threads and a Queue to
simulate non-blocking calls. This is happens only when running
with the native Windows version of Python, meaning Linux and Cygwin
are not affected by this change.
