Refactor linker allocator

Makes it reusable for different fixed sized and not very
big structures (<PAGE_SIZE).

Use __LP64__ instead of __LP32__ in sched.h

Gcc defines only __LP64__ so testing __LP32__ will always be false.

Reduce stack usage of tmpfile(3).

Also ensure that none of our home-grown code uses more than 2KiB per frame.

Add getmntent_r to our collection of <mntent.h> compatibility stubs.

This helps build 'external/flo' out of the box.

Consistently use #if defined(__BIONIC__) in tests.

I've also switched some tests to be positive rather than negative,
because !defined is slightly harder to reason about and there are
only two cases: bionic and glibc.

Upgrade to tzdata2014c.

From the release notes:

  Changes affecting near-future time stamps

    Egypt observes DST starting 2014-05-15 at 24:00.
    (Thanks to Ahmad El-Dardiry and Gunther Vermier.)
    Details have not been announced, except that DST will not be
    observed during Ramadan.  Guess that DST will stop during the same
    Ramadan dates as Morocco, and that Egypt's future spring and fall
    transitions will be the same as 2010 when it last observed DST,
    namely April's last Friday at 00:00 to September's last Thursday at
    23:00 standard time.  Also, guess that Ramadan transitions will be
    at 00:00 standard time.

Introduce netd_client, a dynamic library that talks to netd.

The library exists outside bionic. It is dynamically loaded, to replace selected
standard socket syscalls with versions that talk to netd.

Change connect() to use the library if available.

Fix build (take two).

Make sure __netdClientDispatch is defined in the same set of libraries that
refer to it (e.g.: with connect.cpp).
