This works (by reading /etc/localtime) on NetBSD, but not on Android
since we have no such file. Fix that by using our equivalent system
property instead.
Also s/time zone/timezone/ in documentation and comments. We've always
been inconsistent about this (as is upstream in code comments and
documentation) but it seems especially odd now we expose a _type_ that
spells it "timezone" to talk of "time zone" even as we're describing
that type and its associated functions.

These docs refer to the old coverage workflow from the Android.mk
build.
AFAIK there's no way to get coverage for the host tests, so that part
was removed.
Test: followed the docs, got coverage data

Move /system dependency on tz_version to bionic from core-libart.
The file is not used by code but is useful on device to identify
the format / version / origin of the tzdata file. The
tz_version file identifies the Android release (e.g. 3.1 == Q), which
implies the version of zic used to generate tzdata, and any Android
revision of the tzdata (e.g. 2019a v2) that may have taken place. The
file was previously used by by the tzdatacheck binary but it has since
switched to using the copy in the runtime module.
The bionic README.md is also updated here to reflect latest locations of
scripts.

Also fix formatting of "What's in libc/?" section, and remove obsolete
include/machine.
Also unify # vs --- syntax.

Also start breaking up the monolithic top level README.md, pulling the
32-bit ABI stuff out into its own file, and moving the remaining benchmark
documentation in with the rest of the benchmark documentation.

The major components of the rewrite:
- Completely remove the qemu shared library code. Nobody was using it
and it appears to have broken at some point.
- Adds the ability to enable/disable different options independently.
- Adds a new option that can enable the backtrace on alloc/free when
a process gets a specific signal.
- Adds a new way to enable malloc debug. If a special property is
set, and the process has an environment variable set, then debug
malloc will be enabled. This allows something that might be
a derivative of app_process to be started with an environment variable
being enabled.
- get_malloc_leak_info() used to return one element for each pointer that
had the exact same backtrace. The new version returns information for
every one of the pointers with same backtrace. It turns out ddms already
automatically coalesces these, so the old method simply hid the fact
that there where multiple pointers with the same amount of backtrace.
- Moved all of the malloc debug specific code into the library.
Nothing related to the malloc debug data structures remains in libc.
- Removed the calls to the debug malloc cleanup routine. Instead, I
added an atexit call with the debug malloc cleanup routine. This gets
around most problems related to the timing of doing the cleanup.
The new properties and environment variables:
libc.debug.malloc.options
Set by option name (such as "backtrace"). Setting this to a bad value
will cause a usage statement to be printed to the log.
libc.debug.malloc.program
Same as before. If this is set, then only the program named will
be launched with malloc debug enabled. This is not a complete match,
but if any part of the property is in the program name, malloc debug is
enabled.
libc.debug.malloc.env_enabled
If set, then malloc debug is only enabled if the running process has the
environment variable LIBC_DEBUG_MALLOC_ENABLE set.

Most of these are just aesthetic, but the `_FILE_OFFSET_BITS` probably
would have rendered partly as italics and skipped some underscores.
GitHub's Markdown also doesn't identify our bug URLs as links, so mark
them explicitly.
