Partial read and write happen and it is better to try again
unless there is some hard error. This is meant to fix some
flaky behavior of emulator pipe services, hopefully.

Traditionally, qemu_pipe has both the declaration and implentation of each
function in one header file--qemu_pipe.h, and it is getting incovenient to
maintain.
This CL separates the implementation of functions from the header file,
and makes qemu_pipe a static library for other modules to link to.
Note that the interface and implementation of qemu_pipe are kept unchanged,
and future CLs will enhance the implementation to make it more reliable and
more compatible with old and new API levels.
Following projects are affected by this refactoring, and they are modified
accordingly:
device/generic/goldfish
device/generic/goldfish-opengl
hardware/ril/reference-ril

This modifies init's loading of SELinux policy into the kernel to
load the split (platform/system vs non-platform/vendor) policy if it's
present. If the split policy is not present, the usual monolithic
policy is loaded into the kernel, same as before.
Split policy is loaded by first compiling it from CIL form using
secilc compiler into the conventional monolithic/compiled form which
is then loaded into the kernel.
The build system has not yet been modified to place split policy onto
devices. Thus, this commit currently has no effect. For testing split
policy, build plat_sepolicy.cil, nonplat_sepolicy.cil, and
mapping_sepolicy.cil, and place them into the root directory of the
device.
The following tests were performed for a device with monolithic policy
and for the same device with split policy.
Test: Device boots, no new denials
Test: Play Movies plays back movies
Test: Load ip6.me im Chrome

- Replace all NULL, macro defined to 0, with nullptr. nullptr is a
keyword of type nullptr_t, with a value of (nullptr_t)0, a pointer
type of sizeof(void*) that can not confusingly promote to an int.
- Replace all boolean evaluations of values against 0, NULL, and
nullptr with direct, ! or !! as appropriate.
- Note that thread_stopped should be semaphore, defer that to
a non-code-quality improvement patch.
- Check for null context in android_logcat_destroy.

We don't need early mount in recovery mode for security considerations,

menu. This CL checks the existence of file "/sbin/recovery" and skip
early mount when it is found.

Deal with cache miss in the event tag map resources and switch to
"Plan B" to ask long-path to logd for a determination on the tag,
name and format.
logcat-unit-tests liblogcat.descriptive does an under-the-hood call
to logd to add a new logtag but the in-process mapping fails to
pick it up because the /dev/event-tag-map map is SHARED PRIVATE for a
few moments to garner some (linux) efficiency with other copies that
are in the process. Without the workaround of marking the mapping
dirty to be reread, we are using this change as the proper workaround
that fixes the later parts of this test.

During early mount property area is not initialized, and as a result an
'eng' build will always incorrectly be detected as a 'secure' build by
early mount code path resulting into verity error and consequent boot
loop.
The change here makes sure the is_device_secure() check works with /
without properties based on the 'eng' build based build flag so the
early mount code works fine both ways.

Treblization requires to locate partner-specific modules in its own
partition. So their own init.rc file could be located in /odm or
/vendor.
This CL is to support those locations for the init.rc.
Additionally thic CL modified import parser to support importing a
relative path.
Test: building succeeded and tested on sailfish with enabling early
mount.

If Device tree values are read for comparison, they produce false
negatives with std::strings due to trailing '\0'. This change
consolidates the triming of trailing null into a single helper function
to be used everywhere fs_mgr reads DT values for comparison or other
reasons where it wishes to have the trailing null trimmed.
