The recent libcore ZoneInfo changes mean that we can no longer
compile libcore's ZoneInfo against the RI. Luckily, the field in
our data file that we needed ZoneInfo for isn't actually used.
This change removes our dependence on libcore.
I've left the field in to avoid a file format change. We can remove
the field if/when we next have a real need to bump the file format.

During pthread_exit, the keys are cleaned. Unfortunately, a call to
free occurs after the cleanup and the memory for some of the keys
is recreated when using jemalloc. The solution is to do the key
cleanup twice.
Also, modify the pthread_detach__leak test to be less flaky
when run on a jemalloc system.

From the release notes:
Changes affecting future time stamps
Russia will subtract an hour from most of its time zones on
2014-10-26 at 02:00 local time. (Thanks to Alexander Krivenyshev.)
There are a few exceptions: Magadan Oblast (Asia/Magadan) and
Zabaykalsky Krai are subtracting two hours; conversely, Chukotka
Autonomous Okrug (Asia/Anadyr), Kamchatka Krai (Asia/Kamchatka),
Kemerovo Oblast (Asia/Novokuznetsk), and the Samara Oblast and the
Udmurt Republic (Europe/Samara) are not changing their clocks. The
changed zones are Europe/Kaliningrad, Europe/Moscow,
Europe/Simferopol, Europe/Volgograd, Asia/Yekaterinburg, Asia/Omsk,
Asia/Novosibirsk, Asia/Krasnoyarsk, Asia/Irkutsk, Asia/Yakutsk,
Asia/Vladivostok, Asia/Khandyga, Asia/Sakhalin, and Asia/Ust-Nera;
Asia/Magadan will have two hours subtracted; and Asia/Novokuznetsk's
time zone abbreviation is affected, but not its UTC offset. Two
zones are added: Asia/Chita (split from Asia/Yakutsk, and also with
two hours subtracted) and Asia/Srednekolymsk (split from
Asia/Magadan, but with only one hour subtracted). (Thanks to Tim
Parenti for much of the above.)
Changes affecting past time stamps
China's five zones have been simplified to two, since the post-1970
differences in the other three seem to have been imaginary. The
zones Asia/Harbin, Asia/Chongqing, and Asia/Kashgar have been
removed; backwards-compatibility links still work, albeit with
different behaviors for time stamps before May 1980. Asia/Urumqi's
1980 transition to UTC+8 has been removed, so that it is now at
UTC+6 and not UTC+8. (Thanks to Luther Ma and to Alois Treindl;
Treindl sent helpful translations of two papers by Guo Qingsheng.)
Some zones have been turned into links, when they differed from
existing zones only for older UTC offsets where the data were likely
invented. These changes affect UTC offsets in pre-1970 time stamps
only. This is similar to the change in release 2013e, except this
time for western Africa. The affected zones are: Africa/Bamako,
Africa/Banjul, Africa/Conakry, Africa/Dakar, Africa/Freetown,
Africa/Lome, Africa/Nouakchott, Africa/Ouagadougou, Africa/Sao_Tome,
and Atlantic/St_Helena. This also affects the
backwards-compatibility link Africa/Timbuktu. (Thanks to Alan
Barrett, Stephen Colebourne, Tim Parenti, and David Patte for
reporting problems in earlier versions of this change.)
Asia/Shanghai's pre-standard-time UT offset has been changed from
8:05:57 to 8:05:43, the location of Xujiahui Observatory. Its
transition to standard time has been changed from 1928 to 1901.
Asia/Taipei switched to JWST on 1896-01-01, then to JST on
1937-10-01, then to CST on 1945-09-21 at 01:00, and did not observe
DST in 1945. In 1946 it observed DST from 05-15 through 09-30; in
1947 from 04-15 through 10-31; and in 1979 from 07-01 through 09-30.
(Thanks to Yu-Cheng Chuang.)
Asia/Riyadh's transition to standard time is now 1947-03-14, not
1950.
Europe/Helsinki's 1942 fall-back transition was 10-04 at 01:00, not
10-03 at 00:00. (Thanks to Konstantin Hyppönen.)
Pacific/Pago_Pago has been changed from UTC-11:30 to UTC-11 for the
period from 1911 to 1950.
Pacific/Chatham has been changed to New Zealand standard time plus
45 minutes for the period before 1957, reflecting a 1956 remark in
the New Zealand parliament.
Europe/Budapest has several pre-1946 corrections: in 1918 the
transition out of DST was on 09-16, not 09-29; in 1919 it was on
11-24, not 09-15; in 1945 it was on 11-01, not 11-03; in 1941 the
transition to DST was 04-08 not 04-06 at 02:00; and there was no DST
in 1920.
Africa/Accra is now assumed to have observed DST from 1920 through
1935.
Time in Russia before 1927 or so has been corrected by a few seconds
in the following zones: Europe/Moscow, Asia/Irkutsk, Asia/Tbilisi,
Asia/Tashkent, Asia/Vladivostok, Asia/Yekaterinburg,
Europe/Helsinki, and Europe/Riga. Also, Moscow's location has been
changed to its Kilometer 0 point. (Thanks to Vladimir Karpinsky for
the Moscow changes.)

Create a method of disabling the debug allocation code paths so that
it's possible to use the libunwindbacktrace library without any
modifications.
Use this path to create and destroy the maps for the process. It's not
stricly necessary in the init code since the symbols are not modified
until after the initialize calls.
Also, remove the debug_XXX source files that doesn't need to be in libc.so.
Fix the maps reading code since it was completely broken for 64 bit.

which is how we never noticed this bug before and (b) the LP64 ones
all use a 64-bit register for the result (and for the syscall number
too).

It seemed like a clever trick to use the internal log message formatting
code in syslog(3), but on reflection that means you can't (for example)
format floating point numbers. This patch switches us over to using good
old vsnprintf(3), even though that requires us to jump through a few hoops.
There's no obvious way to unit test this, so I wrote a little program and
ran that.
