and should not be exported to everything that uses libbase headers.

d10a023208 libbase: make vendor_available
By setting vendor_available, the following may become true:

* a prebuilt library from this release may be used at runtime by
  in a later releasse (by vendor code compiled against this release).
  so this library shouldn't depend on runtime state that may change
  in the future.
* this library may be loaded twice into a single process (potentially
  an old version and a newer version). The symbols will be isolated
  using linker namespaces, but this may break assumptions about 1
  library in 1 process (your singletons will run twice).

Background:

This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.

At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.

It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:

https://android-review.googlesource.com/368372

None of this is enabled unless the device opts into the system/vendor
split with BOARD_VNDK_VERSION := current.

e78ea77f69 bootstat: Refactor init/utils/boot_clock into base/chrono_utils.
Use this for bootstat and init. This replaces the custom uptime parser in
bootstat.

This is a reland of aosp/338325 with a stubbed implementation for Darwin.

This change also has clang_format fixes (automatic).

3d5729402e Fix timeouts for android::base::WaitForProperty*
std::chrono doesn't handle integer overflow, so using
std::chrono::milliseconds::max() to indicate an infinite timeout is
not handled well in the current code.  It causes an 'absolute_timeout'
earlier in time than 'now' and causes the associated WaitForProperty*
functions to return immediately.

Also, any duration_cast from relative_timeout to nanoseconds would
cause the same issue, as it would overflow in the conversion and
result in an invalid results.

This change prevents any duration_casts of relative_timeout to
nanoseconds and replaces the logic to wait on an absolute timeout with
logic that compares the time elapsed to the provided relative timeout.

This change also includes a test that std::chrono::milliseconds::max()
does not return immediately and that negative values do return immediately.

Test: Boot bullhead + libbase_test

5b4eb23cfd Remove extraneous .clang-format files
The .clang-format files in the base, debuggerd, adb, libprocinfo, and
fastboot subdirectories each differ slightly from the top level
.clang-format-2 and .clang-format-4, but not in a substantially
meaningful way, as the source files in those directories have not been
re-formatted with clang-format.  Therefore, let's reduce the
differences and use only the two top level clang-format files.

Secondly perform some small clean-up of the top level .clang-format
files.  AllowShortBlocksOnASingleLine is already false in the Google
style, so it can be removed.  AllowShortFunctionsOnASingleLine should
not change between the -2 and -4 versions, so leave it at the Google
default style in both, which is 'All'.

b0775ca517 Switch to memcpy for accessing misaligned data.
Bug: http://b/31532493

Using misaligned pointers forces us to potentially take the address of
members in a packed structure (which is now a warning/error in the
latest Clang). Using memcpy() is the proper way to handle this kind of
problem, as the compiler can insert the proper instructions (and usually
elide the memcpy() entirely).

Test: Built correctly with updated compilers.
