The marked library(ies) were available to the APEXes via the hand-written
whitelist in build/soong/apex/apex.go. Trying to remove the whitelist
by adding apex_available property to the Android.bp of the libraries.
In this change, following libs were made available to all apexes because
their usage is quite common and there is no reason to restrict them
to some APEXes.
* libbase_headers
* libcutils, libcutils_headers
* libutils_headers, libsystem_headers
* liblog_headers
* libbacktrace, libbacktrace_headers
* libcrypto_utils

logger_entry has a hdr_size field meant for backwards compatibility,
however there are a few checks that expect it to be a specific size.
More problematically, it has a variable length array element, msg[0]
at the end, that would be incorrect if the header size was not kept
static.
This change fixes up those issues to facilitate future additions.

liblog is a platform library that provides stable C API. There is no
need to include the library, especialy by statically linking to it, in
any APEX. It not only wastes the storage/ram, but also is incorrect
because the socket interface to logd which is implemented in liblog is
not guaranteed to be stable.
Fixing this issue by converting static_libs: ["liblog"] into
shared_libs: ["liblog"], in which case the dependency to the library
is satisfied via the stub variant of the library.
As a result, we could restrict the availablity of the library to
the platform and the runtime APEX.

See the previous commit moving SetLogger and SetAborter to liblog for
motivation.
This creates more harmony between the two mechanisms in libbase and
liblog for checking loggability.
Currently:
1) libbase filters all messages based on its minimum log priority. For
example, if minimum log priority in libbase remained at its
default, but a tag was specifically opted into DEBUG logs via
log.tag.<tag>, libbase would not print this log.
2) liblog ignores libbase's minimum log priority. For example if a
process called SetMinimumLogPriority(WARNING) but used a library
that logged via liblog's ALOGI macro, that log would still be
printed even though the process intends on filtering out those INFO
messages.
With this change:
1) If both a minimum log priority and a priority through log.tag.<tag>
are set, then the lower of the two values is used.
2) If only one or the other is set, then that value is used. This
fixes the two issues described above.
3) If neither of these values are set, then the default of using INFO
is unchanged.

libbase is copied into each APEX module which requires it, meaning
that there may be multiple instances of libbase running within a
single process with their own copy of libbase's globals. This means
that SetLogger() and SetAborter() will only impact logs from the
instance of libbase that calls it. This change moves this state to
liblog, since it will only ever have one instance in a single
process.
One major side-effect here is that now both ALOGE style and LOG(...)
style logs will be handled through the same logger function. For
example, a logger specified through libbase's SetLogger() will now see
logs sent to liblog through ALOGE(). This is intended behavior.
A second side-effect is that libbase's stderr logger is used for all
host logging now. It's simply a better logging default than the
fake_log_device logger in liblog currently and makes ALOGE and
LOG(...) logs on host follow the same format.

The current system of using atomics isn't thread safe and may result
in doubly closing FDs or closing actively used FDs. The safest way to
do this is to use a rwlock, which should not have a much higher
overhead than the atomics do, as a vast majority of the time, there
will not be writers.
This moves us further away from using the transport interface, which
will be removed. Each writer should be self contained, without a
separate open or available function.
Also, keep the pmsg fd open if it is opened by
__android_log_pmsg_file_write(). This fd was closed due to issues
with zygote, but it looks like it is only called by recovery now, so
there is no reason to close this fd at the end of that function.

This code was introduced to help performance by skipping sending these
messages to logd when logd would later drop them. However it has
multiple flaws:
1) Event logs aren't super common and non-loggable event logs are even
less common, so it would be a trivial benefit if any.
2) This code is not particularly safe as written, which is even
acknowledged in the comments.
3) This forces processes that write event logs to allocate a rather
sizable amount of memory.
Therefore, it's better to simply remove this and let logd drop these
messages when it receives them.

The current version requires callers to supply a string with 32 extra
bytes for liblog to internally prepend "setPruneList ", and to have
enough space to parse logd's return string. That is an unacceptable
requirement on callers.
This change removes that requirement by having liblog allocate the
needed std::string in any case.
It also stops writing back the 'success' or 'Invalid' string to the
caller's buffer, since that is redundant as well.
Test: changing prune settings works.

We don't need to be so strict about this comparison. It's possible
that logd will extend the message that it passes to readers in the
future, and since we have a hdr_size parameter it can do so in a
backwards compatible way, as long as we loosen this restriction.
This keeps a sane upper bound that the hdr_size cannot be larger than
the log message itself.
