  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.)

debuggerd: if PR_GET_DUMPABLE=0, don't ask for dumping

PR_GET_DUMPABLE is used by an application to indicate whether or
not core dumps / PTRACE_ATTACH should work.

Security sensitive applications often set PR_SET_DUMPABLE to 0 to
disable core dumps, to avoid leaking sensitive memory to persistent
storage. Similarly, they also set PR_SET_DUMPABLE to zero to prevent
PTRACE_ATTACH from working, again to avoid leaking the contents
of sensitive memory.

Honor PR_GET_DUMPABLE when connecting to debuggerd. If an application
has said it doesn't want its memory dumped, then we shouldn't
ask debuggerd to dump memory on its behalf.
