Switch from /data/misc/reboot/last_reboot_reason to persistent
Android property persist.sys.boot.reason for indicating why the
device is rebooted or shutdown.
persist.sys.boot.reason has a standard as outlined in b/63736262 and
the associated investigation. Made adjustments to the values so that
we did not create a problem even before we started. Compliance is
part of the tests in boot_reason_test.sh.

With full disk encryption, a temporary /data partition is mounted to
start a minimum subset of the frameworks. Later, once /data can be
decrypted it is mounted again. load_persist_props is called both when
the temporary /data partition is mounted and again after the real
/data is mounted; this is a mistake.
This change checks to see if we're a FDE device and if so, returns the
first time load_persist_props is called.
Test: boot bullhead (FDE) with and without boot pin and check that
persistent properties are loaded
Test: boot sailfish (FBE) and check that persistent properties are loaded

- Rewrite the Maps::Parse to use open, and a buffer on the stack.
- Rewrite the line parser away from sscanf. The current way sscanf
is used does not catch many malformed lines. In addition, this
new version improves performance by 50% over sscanf on sailfish.
- Add a lot of unit tests for the parser to make sure there are
no problems. In addition, add a special line that was not rejected
with the previous version of the code.
- Add new accessor to get the map at a particular index.
- Add a backtrace benchmark for map creation for both new and old.
This cl results in ~5% speedup and makes the new unwinder map creation
about the same for 64 bit. It's still a bit slower, but not by much.
On 32 bit, we are still about 5% slower than the old creation method,
though.

* changes:
init: enable error reporting of builtin functions
init: log Service failures via Result<T>
init: pass errors from one Result<T> to another better
init: cleanup environment handling
The feature references a new file created by the selinux make system
that is stored on device under /system/etc/selinux/ which contains a
scontext, tcontext, tclass, and the bug they map to. logd will
reference this map every time an selinux denial comes through to see if
it's a known denial with a bug attached and then add the bug number to
the denial that's logged.

Enable error reporting when builtin functions fail. These errors are
now reported with full context including the source file and line
number, e.g.
init: Command 'write /sys/module/subsystem_restart/parameters/enable_debug ${persist.sys.ssr.enable_debug}' action=early-boot (/init.bullhead.rc:84) took 0ms and failed: cannot expand '${persist.sys.ssr.enable_debug}'
There are two small caveats:
1) There are nearly 200 reports of builtins failure due to "No such
file or directory". Many of these are due to legacy paths included
in rootdir/init.rc. Until they are cleaned up, reporting of these
failures is disabled.
2) Similarly, symlink is often used to create backwards compatible
symlinks. By their very nature, these calls are expected to fail
on newer systems that do already use the new path. Due to this,
failures of symlink due to EEXIST are not reported.
Bug: 38038887
Test: boot bullhead, only see true errors reported from builtins.

Result<T> currently has two problems,
1) A failing Result<T> cannot be easily constructed from a Result<U>'s
error.
2) errno is lost when passing .error() through multiple Result<T>'s
This change fixes both problems having Result<T>::error() return a
ResultError class that contains the std::string error message and int
errno.
It additionally has ostream operators to continue to allow printing
the error string directly to an ostream and also to pass the errno
through to another Result<T> class via Error() creation.
Lastly, it provides a new constructor for Result<T> for ResultError,
such that a Result<T> can be constructed from Result<U>::error().
Test: boot bullhead, init unit tests

Init keep its own copy of the environment that it uses for execve when
starting services. This is unnecessary however as libc already has
functions that mutate the environment and the environment that init
uses is clean for starting services. This change removes init's copy
of the environment and uses the libc functions instead.
This also makes small clean-up to the way the Service class stores
service specific environment variables.
Test: boot bullhead

As a VNDK-SP module, Android.bp must have 'vndk' tag as well as
'vendor_available: true'.
The 'vndk' tag for VNDK-SP formated as follows:
vndk: {
enabled: true,
support_system_process: true,
},
VNDK-SP modules will be installed both in system/lib(64) as normal
and in system/lib(64)/vndk-sp as a vendor variant.

(cherry picked from commit aeb68e86e4)
Extend device selection to allow selecting a specific transport via
monotonically increasing identifier (visible in devices -l).
This is useful when using multiple devices (like hikey960...) that
have identical bogus serial numbers like 0123456789ABCDEF.

Currently, init attempts to set ro.boottime.<service> properties
whenever a service starts, however since these properties are ro. this
means that an error is printed whenever a service is restarted.
Since these properties are intended for reporting boottime, these
subsequent writes during restarts are erroneous and therefore this
change stops attempting to write them, thus silencing the error.
Test: boot bullhead, restart processes, observe no error print
