e9a7b81d4a Add new mallopt M_LOG_STATS. 
This new mallopt cause statistics of the allocator to be printed in
the log.

Add a stats print for jemalloc.

This is designed to be used as part of a dumpsys meminfo --XXXX
option so that it's easier to get information about apps that
have an unusual memory footprint.

Test: Unit tests pass.
Test: Ran on a device using jemalloc and verified log data.
Test: Ran on a device using scudo and verified log data.

9dbfe8bb69 <arpa/nameser.h>: rationalize __INTRODUCED_IN. 
Investigation shows that the symbols that claimed to have been in 32-bit
builds one API level earlier than in 64-bit builds actually weren't ---
everything was actually API level 22. This patch fixes the libc.map.txt
to match reality, and then simplifies the __INTRODUCED_IN()
incantations.

Investigation also shows that we have a bunch of unused #defines, so
this patch removes the ones that don't correspond to functions we
actually expose.

2bd4316bd6 Expose tzalloc()/localtime_rz()/mktime_z()/tzfree(). 
* Rationale

The question often comes up of how to use multiple time zones in C code.
If you're single-threaded, you can just use setenv() to manipulate $TZ.
toybox does this, for example. But that's not thread-safe in two
distinct ways: firstly, getenv() is not thread-safe with respect to
modifications to the environment (and between the way putenv() is
specified and the existence of environ, it's not obvious how to fully
fix that), and secondly the _caller_ needs to ensure that no other
threads are using tzset() or any function that behaves "as if" tzset()
was called (which is neither easy to determine nor easy to ensure).

This isn't a bigger problem because most of the time the right answer
is to stop pretending that libc is at all suitable for any i18n, and
switch to icu4c instead. (The NDK icu4c headers do not include ucal_*,
so this is not a realistic option for most applications.)

But what if you're somewhere in between? Like the rust chrono library,
for example? What then?

Currently their "least worst" option is to reinvent the entire wheel and
read our tzdata files. Which isn't a great solution for anyone, for
obvious maintainability reasons.

So it's probably time we broke the catch-22 here and joined NetBSD in
offering a less broken API than standard C has for the last 40 years.
Sure, any would-be caller will have to have a separate "is this
Android?" and even "is this API level >= 35?" path, but that will fix
itself sometime in the 2030s when developers can just assume "yes, it
is", whereas if we keep putting off exposing anything, this problem
never gets solved.

(No-one's bothered to try to implement the std::chrono::time_zone
functionality in libc++ yet, but they'll face a similar problem if/when
they do.)

* Implementation

The good news is that tzcode already implements these functions, so
there's relatively little here.

I've chosen not to expose `struct state` because `struct __timezone_t`
makes for clearer error messages, given that compiler diagnostics will
show the underlying type name (`struct __timezone_t*`) rather than the
typedef name (`timezone_t`) that's used in calling code.

I've moved us over to FreeBSD's wcsftime() rather than keep the OpenBSD
one building --- I've long wanted to only have one implementation here,
and FreeBSD is already doing the "convert back and forth, calling the
non-wide function in the middle" dance that I'd hoped to get round to
doing myself someday. This should mean that our strftime() and
wcsftime() behaviors can't easily diverge in future, plus macOS/iOS are
mostly FreeBSD, so any bugs will likely be interoperable with the other
major mobile operating system, so there's something nice for everyone
there!

The FreeBSD wcsftime() implementation includes a wcsftime_l()
implementation, so that's one stub we can remove. The flip side of that
is that it uses mbsrtowcs_l() and wcsrtombs_l() which we didn't
previously have. So expose those as aliases of mbsrtowcs() and
wcsrtombs().
