5e9f3d44a3 Allow setting an arbitrary alignment for an entry.
The current code only allows the creation of an entry that is 32 bit
aligned.

e6884ce56f Add a ZipArchiveStreamEntry class.
This allows someone to stream the data out of a zip archive
instead of extracting to a file or to memory.

Included in this change is a small cleanup of the makefile.

08c9891c9c libbinderwrapper: Add BinderWrapper::GetOrCreateInstance()
In libraries relying on binder it is useful to be able to obtain an
existing copy of BinderWrapper or create one if it doesn't exist.

This allows to abstract the actual RPC (binder) from clients who have
no other dependencies on this RPC.

b6a8d41e2a logger.h: reduce maximum payload so sum is page size
Reduce maximum log payload so that the sum with the maximum
length header logger_entry_v4 is a page size. This is a
performance measure.

Expect side effects, truncates messages 8 bytes earlier. The
length has a long history (2008) so there may be non-C code
somewhere that has it hard-coded rather than reflecting this
header. CTS tests may need to be adjusted.

9b292f563e logger.h: Add definition for logger_entry_v4
Extends logger_entry_v3 to add an uid field and moves some fields to
unsigned (easier to have zero'd bit-field for future adjustments).

Still no version field, not crossing that bridge, historical reasons.

If the start time is about to wrap or get pruned in the specified log
buffers, then wakeup and dump the logs; or wakeup on timeout,
whichever comes first.

2d2e0a5c5e liblog: resolve deadlocks
Although ever present, an increased regression introduced with
commit b6bee33182 (liblog: logd:
support logd.timestamp = monotonic).

A signal handler can interrupt in locked context, if log is written
in the signal handler, we are in deadlock. To reduce the contention
and chances for this problem separate out timestamp lock from is
loggable lock to reduce contention situations. Provide a best-guess
response if lock would fail in timestamp path.

Use a common lock() inline within each module, with a comment speaking
to the issues surrounding calling a function that has a mutex within
a signal handler.

ToDo: Hold off signals temporarily in mainline, restart when unblock.
      Can not use pthread_sigmask(SIG_BLOCK,,) as it breaks AtCmd.

c39ba5ae32 Enable hidepid=2 on /proc
Add the following mount options to the /proc filesystem:

  hidepid=2,gid=3009

This change blocks /proc access unless you're in group 3009
(aka AID_READPROC).

Please see
  https://github.com/torvalds/linux/blob/master/Documentation/filesystems/proc.txt
for documentation on the hidepid option.

hidepid=2 is preferred over hidepid=1 since it leaks less information
and doesn't generate SELinux ptrace denials when trying to access
/proc without being in the proper group.

Add AID_READPROC to processes which need to access /proc entries for
other UIDs.
