This commit also deprecates the `as_string` and `as_slice` free functions in the
`string` and `vec` modules.

This commit shards the broad `core` feature of the libcore library into finer
grained features. This split groups together similar APIs and enables tracking
each API separately, giving a better sense of where each feature is within the
stabilization process.
A few minor APIs were deprecated along the way:
* Iterator::reverse_in_place
* marker::NoCopy

Looks better without all that wasted whitespace

Various methods in both libcore/char.rs and librustc_unicode/char.rs were previously marked with #[inline], now every method is marked in char's impl blocks.
Partially fixes #26124.
EDIT: I'm not familiar with pull reqests (yet), apparently Github added my second commit to thit PR...
Fixes #26124

But not str::to_titlecase which would require UAX#29 Unicode Text Segmentation
which we decided not to include in of `std`:
https://github.com/rust-lang/rfcs/pull/1054
|

As a result, the iterator returned by `char::to_uppercase` sometimes
yields two or three `char`s instead of just one.

This adds 120 mappings:

Helps prevent mixed content warnings if accessing docs over HTTPS.
Closes #25459
|
|
Even spelled out, one would say 'a Universal Character Set'
|
|
For now, words() is left in (but deprecated), and Words is a type alias for
struct SplitWhitespace.
Also cleaned up references to s.words() throughout codebase.
Closes #15628

Words struct was stabilied by mistake. Unstabilize.

Apply optimization described in
https://github.com/rust-lang/regex/pull/73#issuecomment-93777126
to rust's copy of `unicode.py`.
This shrinks librustc_unicode's tables.rs from 479kB to 456kB,
and should improve performance slightly for related operations
(e.g., is_alphabetic(), is_xid_start(), etc).
In addition, pull in fix from @dscorbett's commit
d25c39f86568a147f9b7080c25711fb1f98f056a in regex, which
makes `load_properties()` more tolerant of whitespace
in the Unicode tables. (This fix does not result in any
changes to tables.rs, but could if the Unicode tables
change in the future.)

This patch
1. renames libunicode to librustc_unicode,
2. deprecates several pieces of libunicode (see below), and
3. removes references to deprecated functions from
librustc_driver and libsyntax. This may change pretty-printed
output from these modules in cases involving wide or combining
characters used in filenames, identifiers, etc.
The following functions are marked deprecated:
1. char.width() and str.width():
--> use unicode-width crate
2. str.graphemes() and str.grapheme_indices():
--> use unicode-segmentation crate
3. str.nfd_chars(), str.nfkd_chars(), str.nfc_chars(), str.nfkc_chars(),
char.compose(), char.decompose_canonical(), char.decompose_compatible(),
char.canonical_combining_class():
--> use unicode-normalization crate
