c30f248cd4 Add vendor_available to liblog_headers.
Renamed NDK headers to "liblog_ndk_headers"
(these names aren't used anywhere).

libutils_headers now properly export liblog_headers.

58e06c5f94 Use void instead of no parameters in 2 function declarations.
In compiling some code with a picky "Android.mk" file, it is not happy
with a function declaration that looks like:

    void foo();

It requires:

    void foo(void);

This commit changes that for 2 functions in "log.h".

Test: Build both Android and the code with a picky "Android.mk".

9ffeab85bf Allow SLOG* to vendors
Not only vendor libs, but also Android libs that are marked as
vendor_available are using SLOG*. Since both pure vendor libs and
Android libs available to vendors are using the same liblog headers for
VNDK, SLOG* needs to be visible via the headers.

Bug: 63088165
Test: BOARD_VNDK_VERSION=current m -j ATFWD-daemon
(or any other vendor modules using SLOG*)

928e606d5a liblog: test: enoent requires userdebug or eng to run
(cherry picked from commit 38dad6c9e4)

Bypass test if we do not have all the prerequisites to run this check
of liblog failure propagation.  We need to be root, or be able to
call su, in order to temporarily stop logd to measure the error
response from liblog.  Basically a "user" build can not have the
levers to deny or fail the logger, preventing our ability to run the
liblog.enoent test.

ac225780dd Move libc_logging to libasync_safe.
Move the name of the "private/libc_logging.h" header to <async_safe/log.h>.

For use of libc_malloc_debug_backtrace, remove the libc_logging library.
The library now includes the async safe log functions.

Remove the references to libc_logging.cpp in liblog, it isn't needed because
the code is already protected by a check of the __ANDROID__ define.

Test: Compiled and boot bullhead device.
Test: Run debuggerd unit tests.
Test: Run liblog unit tests on target and host.
Test: Run libmemunreachable unit tests (these tests are flaky though).

01bdb04be6 liblog: allow event tags to include some punctuations
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.

5768d3d976 liblog: logprint supports number of seconds time event field
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.
