IANA changes:
Briefly: Southern Chile moves from -04/-03 to -03, and Mongolia
discontinues DST.
Changes to future time stamps
Mongolia no longer observes DST. (Thanks to Ganbold Tsagaankhuu.)
Chile's Region of Magallanes moves from -04/-03 to -03 year-round.
Its clocks diverge from America/Santiago starting 2017-05-13 at
23:00, hiving off a new zone America/Punta_Arenas. Although the
Chilean government says this change expires in May 2019, for now
assume it's permanent. (Thanks to Juan Correa and Deborah
Goldsmith.) This also affects Antarctica/Palmer.
Changes to past time stamps
Fix many entries for historical time stamps for Europe/Madrid
before 1979, to agree with tables compiled by Pere Planesas of the
National Astronomical Observatory of Spain. As a side effect,
this changes some time stamps for Africa/Ceuta before 1929, which
are probably guesswork anyway. (Thanks to Steve Allen and
Pierpaolo Bernardi for the heads-ups, and to Michael Deckers for
correcting the 1901 transition.)
Ecuador observed DST from 1992-11-28 to 1993-02-05.
(Thanks to Alois Treindl.)
Asia/Atyrau and Asia/Oral were at +03 (not +04) before 1930-06-21.
(Thanks to Stepan Golosunov.)
Changes to past and future time zone abbreviations
Switch to numeric time zone abbreviations for South America, as
part of the ongoing project of removing invented abbreviations.
This avoids the need to invent an abbreviation for the new Chilean
new zone. Similarly, switch from invented to numeric time zone
abbreviations for Afghanistan, American Samoa, the Azores,
Bangladesh, Bhutan, the British Indian Ocean Territory, Brunei,
Cape Verde, Chatham Is, Christmas I, Cocos (Keeling) Is, Cook Is,
Dubai, East Timor, Eucla, Fiji, French Polynesia, Greenland,
Indochina, Iran, Iraq, Kiribati, Lord Howe, Macquarie, Malaysia,
the Maldives, Marshall Is, Mauritius, Micronesia, Mongolia,
Myanmar, Nauru, Nepal, New Caledonia, Niue, Norfolk I, Palau,
Papua New Guinea, the Philippines, Pitcairn, Qatar, Réunion, St
Pierre & Miquelon, Samoa, Saudi Arabia, Seychelles, Singapore,
Solomon Is, Tokelau, Tuvalu, Wake, Vanuatu, Wallis & Futuna, and
Xinjiang; for 20-minute daylight saving time in Ghana before 1943;
for half-hour daylight saving time in Belize before 1944 and in
the Dominican Republic before 1975; and for Canary Islands before
1946, for Guinea-Bissau before 1975, for Iceland before 1969, for
Indian Summer Time before 1942, for Indonesia before around 1964,
for Kenya before 1960, for Liberia before 1973, for Madeira before
1967, for Namibia before 1943, for the Netherlands in 1937-9, for
Pakistan before 1971, for Western Sahara before 1977, and for
Zaporozhye in 1880-1924.
For Alaska time from 1900 through 1967, instead of "CAT" use the
abbreviation "AST", the abbreviation commonly used at the time
(Atlantic Standard Time had not been standardized yet). Use "AWT"
and "APT" instead of the invented abbreviations "CAWT" and "CAPT".
Use "CST" and "CDT" instead of invented abbreviations for Macau
before 1999 and Taiwan before 1938, and use "JST" instead of the
invented abbreviation "JCST" for Japan and Korea before 1938.

The previous versions of the scripts did a lot of redundant changes
and were hard to follow.
I rewrote most of update_all.py so that it's clear about what's going on.
I updated clean_header.py to change the cleanupFile function so that
there is no magic about where the destination file is going to wind up.
Now the caller specifies the final location.
I updated utils.py so that if you are trying to do an update in one
location, but your lunch target is from another location, it causes
an error.

Test: Ran the updater and verified it works properly.
Test: Verified that doing an update in one tree to another tree
Test: fails.
Apparently that "backdoor" is no longer needed - the proper way is
to reinitialize properties:
https://android-review.googlesource.com/#/c/181794/24/tests/system_properties_test.cpp
Also removes mentions of libnativehelper test (it no longer uses
__system_property_area__) and removes useless "extern" declaration
(actual use was removed long ago).
Test: refactoring CL, existsing tests still pass

__system_property_set sometimes produces broken_pipe error
when trying to write a property.
This change improves error messages and uses writev() instead
of sequence of send() calls.

This seemed to be the only place in bionic where a fence on a
performance-critical path could be easily replaced by a stronger
load/store order constraint. Do so.
On x86 this should generate the same code either way. Based on
microbenchmarks of the relevant ARM instructions, this is currently
performance-neutral in this kind of context. But in the future, the
newly generated acquire loads should give us a performance benefit.

Running this periodically and checking in the results is not working
out, since the result is just that I'm having to spend a lot of time
cleaning up the headers every time I need to update them in the NDK.
Run the versioner as part of the build instead. This way bionic
header changes behave like the rest of the NDK headers and will
affect NDK builds in the platform *immediately*.
Remove the preupload hook for the versioner since it's part of the
normal build now.
The versioner's dependencies directory needs to be moved because
soong won't let us try to do things outside our module's directory
(in this case libc).
Unfortunately this means we need to build the versioner for Darwin,
because we now need it to perform a platform build.

Thread local buffers were using pthread_setspecific for storage with
lazy initialization. pthread_setspecific shares TLS slots between the
linker and libc.so, so thread local buffers being initialized in a
different order between libc.so and the linker meant that bad things
would happen (manifesting as snprintf not working because the
locale was mangled)

The default locale is POSIX, not C.UTF-8. POSIX explicitly states
that MB_CUR_MAX is 1 for the POSIX locale:

So far this is the only issue we've hit in vendor code, and we've hit
it several times already. Rather than try to fix bullhead (the current
problem), let's just admit that the special case of 0 is a lot less
worrying.
Also fix the test expectations to correspond to the new abort message.
