(cherry pick from commit c158456f50)
- Add support for "log.tag" and "persist.log.tag" global
logging properties, effectively a runtime default minimum
logging level.
- Add a thread-safe single level cache plus selective logic for the
four properties being checked to help speed up logging decision
on subsequent identical calls.
- Using new __system_property_area_serial() to make for
efficient (<100ns) handling of cache misses. Despite adding
two new properties, we are 8 times faster on subsequent calls
even if the properties do not exist.
- A NULL or blank tag is no longer directed to return default,
it will check the pair of global logging properties first.
- Add liblog.is_loggable gTest
- Fixup liblog.android_logger_get_, allow no content in crash buffer
- Fixup liblog.max_payload, lowered logd priority increases latency

For example, here is the output where the bootanimation is changed
from "d 0 0 part2" to "c 0 0 part2":

When decrementing "n", eventually n will equal zero. When that
happens, n-- underflows. This causes a crash when code which uses
clang's -fsanitize=unsigned-integer-overflow is run.
Avoid trigging an unsigned integer underflow.

This error message has no meaning and makes it look like an unwinding
failure occurred. These messages are showing up more often now
that a lot more of debuggerd is using the ReadWord and Read calls.
If a higher level function wants to indicate there is an error, then
it can add a more meaningful error.

d34e407aeb removed support for
running with SELinux completely disabled. SELinux must either be
in permissive or enforcing mode now.
Remove unnecessary calls to is_selinux_enabled(). It always returns
true now.

In commit 'logd: fix kernel logline stutter'
2c3b300fd8 we introduced log_strtok_r.
as a replacement for strtok_r that dealt with a problem with
some kernel log messages. Fix is to refine definition of
is_timestamp to not match on patterns like [0].

One day we should slim this down. (Maybe implement the "help" versus
"help all" distinction that doesn't currently exist but was documented
before this change.)

* liblog does not use STL, don't link it.
* ASan runtime library depends on liblog, hence liblog can never be
sanitized.

The issue is that adb uses fopen() with "e" (presumably to open the file
with O_CLOEXEC), but that flag causes MSVCRT.DLL to return an error. So
when adb_auth_host.cpp goes to read or write the adbkey files, it fails.
The quick fix is to not use the "e" option on adb host code since it
isn't necessary there, compared to adbd.
An alternative fix would be to have a fopen() wrapper on Windows that
filters out the "e" option.
