We only support unmarshaling into a string or a []byte, but we
previously would try (and panic while) setting a slice of a different
type. The docs say ",innerxml" is ignored if the type is not string or
[]byte, so do that for other slices as well.

This change adds code, originally written by Russ Cox <rsc@golang.org>
and open-sourced by Google, that converts from the "legacy"
binary pprof profile format to a struct representation of the
new protocol buffer pprof profile format.
This code reads the entire binary format for conversion to the
protobuf format. In a future change, we will update the code
to incrementally read and convert segments of the binary format,
so that the entire profile does not need to be stored in memory.
This change also contains contributions by Daria Kolistratova
<daria.kolistratova@intel.com> from the rolled-back change
golang.org/cl/30556 adapting the code to be used by the package
runtime/pprof.
This code also appeared in the change golang.org/cl/32257, which was based

Windows has a limit of 260 characters on normal paths, but it's possible
to use longer paths by using "extended-length paths" that begin with
`\\?\`. This commit attempts to transparently convert an absolute path
to an extended-length path, following the subtly different rules those
paths require. It does not attempt to handle relative paths, which
continue to be passed to the operating system unmodified.
This adds a new test, TestLongPath, to the os package. This test makes
sure that it is possible to write a path at least 400 characters long
and runs on every platform. It also tests symlinks and hardlinks, though
symlinks are not testable with our builder configuration.
HasLink is moved to internal/testenv so it can be used by multiple tests.

Support for ChaCha20-Poly1305 ciphers was recently added to crypto/tls.
These ciphers are preferable in software, but they cannot beat hardware
support for AES-GCM, if present.
This change moves detection for hardware AES-GCM support into
cipher/internal/cipherhw so that it can be used from crypto/tls. Then,
when AES-GCM hardware is present, the AES-GCM cipher suites are
prioritised by default in crypto/tls. (Some servers, such as Google,
respect the client's preference between AES-GCM and ChaCha20-Poly1305.)

On ppc64x, trampolines are used to resolve too-far
branches for internal linking. The external linking,
solution on ppc64x is to split text sections when they
get too large, allowing the external linker to handle
the long branches.
On arm trampolines are generanted for too-far branches
for internal and external linking. When the change
was made recently to enable trampolines for external linking
on arm, that broke the ppc64x fix for too-far branches
with external linking.
The fix adds a check to use trampolines only for internal
linking with ppc64x.
