426b00a29b Fix the way malloc debug returns info.
When I rewrote malloc debug, I accidentally thought that each
value returned in the info buffer contained the number of backtrace
frames in the backtrace. This was incorrect, it should have been
the total number of allocations with the same backtrace.

This is a temporary fix that sets that value to 1. The better fix is
to de-dupe backtraces and then return all allocations of the same size
with the same backtrace.

I updated the documents to describe this.

Bug: 31854476

Test: Unit tests pass.

222272ece9 linker_memory: allow fallback allocator to be turned on and off.
Let the fallback allocator be used on multiple threads (as long as only
one thread is using it at once).

snprintf to a buffer of length PATH_MAX consumes about 7kB of stack.

176cf1f65b Prefer property_contexts from /system & /vendor
This changes system_properties' initialize_properties to prefer
loading property_contexts from /system/etc/selinux &
/vendor/etc/selinux, while falling back to the pre-existing behavior
of loading from /.

Test: Device with *_property_contexts in / boots up fine, no denials
      to do with properties, getprop -Z lists correct labels.
Test: Device with *_property_contexts in /system & /vendor, but not
      in /, boots up fine, no denials to do with properties,
      getprop -Z lists correct labels.
Test: Device with *_property_contexts in /system & vendor and with
      empty *_property_contexts in / boots up fine, no denials to do
      with properties, getprop -Z lists correct labels.

5450f86b31 Fix leak of bionic TLS when threads are detached.
__pthread_internal_free doesn't happen on threads that are detached,
causing the bionic TLS allocation (and guard pages) to be leaked.

Fix the leak, and name the allocations to make things apparent if this
ever happens again.

Bug: http://b/36045112
Test: manually ran a program that detached empty threads

3e0821d7c2 loader: anonymous ns initialization is not required
Anonymous namesapce is zygote-specific workaround and
is not really required for other binaries.

This change allows creating namespaces without initializing
anonymous namespace.

da2082d012 Update timezone data to 2017a
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.

15d3fef0da Refactor the kernel update scripts.
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.

Victor Khimenko
4a92ffd302 Stop using __system_property_area__
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
