Follw-up to https://chromium.googlesource.com/chromium/deps/icu/+/5feb9ad5
(due to a rietveld issue, part 1 was manually pushed).

Update ICU to 58.1 release from ICU 56.1 part2.

Listed below a tiny subset of what's new in 58.1:

  1. Unicode 9.0 from Unicode 8.0
    - Updated character properties including Emoji data up to 4.0beta.
    - Updated grapheme/word/line breaking rules for Emoji sequences and others.

  2. CLDR 30.0.2 from CLDR 28
    - Numerous locale data updates/improvements

  3. Spoofing API changes
  4. Greek uppercasing support as a part of regular case-mapping API.
  5. Line breaking rule file format optimization. This change enables me
     to add CJ loose line breaking rules back (previously, it's dropped
     to save space) so that Blink can use it for CJ.

See http://site.icu-project.org/download/58 for more details on ICU 58.1
and http://site.icu-project.org/download/57 for more details on ICU 57.1

For CLDR 30, see http://cldr.unicode.org/index/downloads/cldr-30 .

The size impact:
   Non-Android: 10,127,200 => 10,128,624 (delta = 1,424 / 0.014%)
   Android: 6,563,152 => 6,571,936 (delta = 8,784 / 0.13%)

Below are the list of changes made on top of the upstream ICU 58.1
in reverse order. Most of these changes were made in 58staging branch
to run trybots and cherry-picked back for this CL. See

The warning complains that StringThreadTest is declared in the global namespace,
but the friend line says `friend class StringThreadTest;` instead of
`friend class ::StringThreadTest`.  MSVC doesn't require this ::, but gcc does
-- without it, the friend line declares a new class in the namespace containing
UnicodeString.

Since StringThreadTest was in test/threadtest which isn't built as part of
Chromium's build and which was removed in upstream ICU in ICU 37392, just
delete the friend line, it has no effect.

Takes an upstream patch (to be included in 56.x release) and patch
our ICU 54.

Clang-specific atomic ops will be used when clang is used to compile but C+11 atomic is disabled/unavailable.

1. Add a one-way (encoding-only/fromUnicode) mapping for U+2212 to
   Shift_JIS, EUC-JP and ISO-2022-JP. The last just uses Shift_JIS.

   See https://www.w3.org/Bugs/Public/show_bug.cgi?id=28661

2. Make GBK aliases list compliant to the encoding spec.

3. Add "xA3xA0 => U+3000" to the GBK (windows-936)  and gb18030. This makes it possible to remove the corresponding override in Blink

4. Modify the following to GBK (windows-936). See [1]
  - Add U+01F9 <=> \xA8\xBF
  - Drop U+E7C8 <=> \xA8\xBF

5. The following change is put on hold (NOT included in the CL)  until the resolution of [1]

  - Add U+1E3F <=> \xA8\xBC
  - Drop U+E7C7 <=> \xA8\xBC

The corresponding Blink CL is https://codereview.chromium.org/1167523003/

1. Update the IANA tz db to 2015b.
  - http://mm.icann.org/pipermail/tz-announce/2015-March/000029.html
  - Mongolia decided to observe DST again in 2015 starting on the last
    Sunday in March.
  - Palestine's DST start date is corrected to be March 28 instead of 27th.

2. Add a script to download the tz database files (update_tz.sh)

3. Check in scripts/make_n_copy_data.sh that I've been using to build ICU
   data/assembly files and update README.chromium.

4. Update android/patch_locale.sh to apply android/brkitr.patch as well.

BUG=473288
TEST=1. In JavaScript console, run the following.
  mar27_2015_1200 = new Date("03/27/2015 12:00Z")
  mar28_2015_1200 = new Date("03/28/2015 12:00Z")
  mar27_2015_1200.toLocaleString("en", {timeZone: "Asia/Gaza"}
  mar28_2015_1200.toLocaleString("en", {timeZone: "Asia/Gaza"}
  apr15_2014_1200 = new Date("04/15/2014 12:00Z")
  apr15_2015_1200 = new Date("04/15/2015 12:00Z")
  apr15_2014_1200.toLocaleString("en", {timeZone: "Asia/Ulan_Bator"}
  apr15_2015_1200.toLocaleString("en", {timeZone: "Asia/Ulan_Bator"}

In Asia/Gaza, Mar 27 12:00Z should be 2PM and mar28 12:00Z should be 3PM.
In Asia/Ulan_Bator, April 15 12:00Z should be 8PM in 2014 and should be 9PM
in 2015. Ulan_Bator does not work due to http://crbug.com/364374.
