closes bpo-37966: Fully implement the UAX GH-15 quick-check algorithm. (GH-15558)
The purpose of the `unicodedata.is_normalized` function is to answer
the question `str == unicodedata.normalized(form, str)` more
efficiently than writing just that, by using the "quick check"
optimization described in the Unicode standard in UAX GH-15.

However, it turns out the code doesn't implement the full algorithm
from the standard, and as a result we often miss the optimization and
end up having to compute the whole normalized string after all.

Implement the standard's algorithm.  This greatly speeds up
`unicodedata.is_normalized` in many cases where our partial variant
of quick-check had been returning MAYBE and the standard algorithm
returns NO.

At a quick test on my desktop, the existing code takes about 4.4 ms/MB
(so 4.4 ns per byte) when the partial quick-check returns MAYBE and it
has to do the slow normalize-and-compare:

  $ build.base/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
      -- 'unicodedata.is_normalized("NFD", s)'
  50 loops, best of 5: 4.39 msec per loop

With this patch, it gets the answer instantly (58 ns) on the same 1 MB
string:

  $ build.dev/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
      -- 'unicodedata.is_normalized("NFD", s)'
  5000000 loops, best of 5: 58.2 nsec per loop

This restores a small optimization that the original version of this
code had for the `unicodedata.normalize` use case.

With this, that case is actually faster than in master!

$ build.base/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
    -- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 561 usec per loop

$ build.dev/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
    -- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 512 usec per loop

bpo-37834: Normalise handling of reparse points on Windows (GH-15370)
bpo-37834: Normalise handling of reparse points on Windows
* ntpath.realpath() and nt.stat() will traverse all supported reparse points (previously was mixed)
* nt.lstat() will let the OS traverse reparse points that are not name surrogates (previously would not traverse any reparse point)
* nt.[l]stat() will only set S_IFLNK for symlinks (previous behaviour)
* nt.readlink() will read destinations for symlinks and junction points only

bpo-1311: os.path.exists('nul') now returns True on Windows
* nt.stat('nul').st_mode is now S_IFCHR (previously was an error)

* bpo-32912: Revert warnings for invalid escape sequences.

DeprecationWarning will continue to be emitted for invalid escape sequences in string and bytes literals in 3.8 just as it did in 3.7.

SyntaxWarning may be emitted in the future. But per mailing list discussion, we don't yet know when because we haven't settled on how to do so in a non-disruptive manner.

bpo-37412: os.getcwdb() now uses UTF-8 on Windows (GH-14396)
The os.getcwdb() function now uses the UTF-8 encoding on Windows,
rather than the ANSI code page: see PEP 529 for the rationale. The
function is no longer deprecated on Windows.

os.getcwd() and os.getcwdb() now detect integer overflow on memory
allocations. On Unix, these functions properly report MemoryError on
memory allocation failure.
