* changes:
liblog: allow event tags to include some punctuations
liblog: logprint supports number of seconds time event field
logcat: test: standardize rest() to let logs land when injecting
event_log_tag parser complains about a period (.) in the name,
we would consider such an enhancement to the tag names possible.
I expect we would want to be able to support alphanumerics,
underscore (_), period (.), minus (-), at (@) and comma (,) for
starters as they are present in the other text log buffer tags.
We introduce a local endOfTag function that is used during parsing and
during android_lookupEventTagNum for submitting new tags. This
function caused us to enforce const char more closely. By filtering
in both places we resolve an issue that could have plagued us if
garbage requests were made.
Test: gTest liblog-unit-tests, logd-unit-tests & logcat-unit-tests

Add s to report time in seconds. The time could be a period, duration
or monotonic, expanded to seconds, minutes, hours and days. gTest has
to acquire a dynamic tag allocation as there are no users of this
feature yet.
Looking to the future, audio media logging has binary content similar
to the binary events structures Android logging uses and they have
a definition of a duration field in their internal binary logging, so
may be of use when we unify the logs.
Test: gTest logcat-unit-tests --gtest_filter=*.descriptive
Bug: 31456426
Change-Id: I262c03775983b3bc7b1b00227ce2bb2b0f357bec
Add an internal rest() function to set the standard for how long we
should wait for a log message to land end to end into the logs. Add
a retry on -EBUSY for all descriptive tests along with a rest() after
log injection so the tests can try to survive heavy Denial Of Service
(DOS) loads. Some of the resting was done at a coarse 1 second, when
200ms will do just fine.
Fix a few pesky issues surrounding test reliability and correctness:
- stdint.h include missing.
- missing a logcat_executable, means logcatd.descriptive testing was
testing logcat instead.
- count of interfering tests is 3 now: logcat, liblogcat and logcatd, if
they all run in the same PID, we have to not fail.
- Added a missed opportunity to add uniqueness to logcat.descriptive sync
test.

These includes are included transitively by liblog, but not by the VNDK
version of liblog.

Test: links with BOARD_VNDK_VERSION := current

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:

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

fs_mgr_update_verity_state() is invoked by 'verity_update_state' in
init.rc. It will then set property "partition.system.verified" and
"partition.vendor.verified" to verify_mode. We should support this for
AVB as well.
Also change the order of static libs in init to fix the build error
after this change:
system/extras/ext4_utils/ext4_crypt.cpp:69: error: undefined reference to 'property_get'
