We need to update these for the multinetwork and atrace APIs. Copy
the baseline android-21 into place first to make the review simpler.

I did a bad job of reviewing this. This is libandroid.so, not a new
library. We need to keep all the old symbols here too. I'll copy in
android-21 first, then add these back.

This reverts commit 00b322bb.

Merge "Fixes the system server hang forever issue caused by the monkey not read completed the sync pipe."

the monkey not read completed the sync pipe.

- Incorrect exception handle.

When no space left on the device the write will
occurs an I/O exception, so we needed to catch it
and continue to read the data of the sync pipe to
aviod the bugreport hang forever.

The only difference between crtbegin_static.c and crtbegin_dynamic.c
is the inclusion of the atexit implementation. Until android-21,
atexit was included in libc.a. After android-21, it's expected to
come from crtbegin. In true NDK fashion, this isn't true across all
architectures. x86 and mips always had this coming from crtbegin.

Copy the android-9 ARM CRT files to android-21 and merge the crtbegin
implementations.

We should probably take a closer look at everything going on here at
some point to make sure we don't need anything new from the bionic
sources.

Test: Improved tests/device/static-executable in the NDK, built ARM
      NDK, tested with and without `--platform android-21`.

The Crypto provider providing the SHA1PRNG algorithm for random number
generation was deprecated.

This algorithm was sometimes incorrectly used to derive keys.

This example provides a helper class and shows how to treat data that
was encrypted in the incorrect way and re-encrypt it in a proper way.

New tag name is coming from upstream (binutils), while the old one
was specific to Android.
