Cleanup.
Save the errno for the calls that fail, and reinstate them for
return. Drop fprintf stutter, one succinct line. Solve a memory
leak in close. Change android_lookupEventTag() to use an
unsigned int so that we can use the full range of uint32_t tags.
Make sure this file compiles clean in C++.

There is no leak since a reference always remained and could get
reused. It just makes sense to also close the event tag map as well
if logging is closed. If we close we also have to fix a tagArray
leak in android_closeEventTagMap().
NB: __android_log_close() already makes an assumption that another
thread is not logging at the same time, which is true in all callers
at this time. There are some partial mitigation strategies if
__android_log_close() is called asynchronously, but not completely
solved at the cost of a lock for every logging call.

- check hdr_size to make sure it is in the expected range
from sizeof entry_v1 to entry (entry_v4).
- alter msg() method to report NULL on invalid hdr_size
- alter all users of msg() method.

Bionic getuid() and getpid() calls cache to reduce the need to
perform a syscall, and also reset their own cache after a vfork().
No more need for liblog to be performing this flawed cache operation.

Soong is always on now, so we don't have to distinguish between
makefiles that should be ignored because Soong is handling them with an
Android.bp file, and makefiles that are still needed with Soong. All
obsolete Android.mk files have been removed, rename all Android.soong.mk
files to Android.mk.
Change-Id: Iabbddcbfb2c837cfd4556241b570474452cc5d4d
These directories all have Android.bp files that are always used now,
delete the Android.mk files.

Ensure len and hdr_size fields are valid and match the return value.
Truncate or zero content as necessary, but do not drop the message.

Going too fast can result in the property not being set
and causing an extreme corner case failure being reported
and blamed on is_loggable functionality.

- periodic failures in apct, dropped second serial test
in refresh_cache, trusting check_cache or global.
- The retry loop to see if is_loggable recovers of 1000
was hiding subsequent tests, drop to 10 retries.
- On the whole, the average performance remains the same.

Note: This code makes the assumption that getpwuid is
thread safe, which it is ONLY ON BIONIC. Thus,
if you attempt to use this on a non-target build, you
may get burned. Thus, an ifndef checking on __BIONIC__
is used to produce a build error if you attempt to do
so.

- check when writing, either LOG_ID_SECURITY, SafetyNet or
