David Pursell b34e4a06ee libcutils/fastboot: improve multi-buffer write.
Fixes libcutils multi-buffer write interface to be more friendly and
hooks into it from the fastboot Socket class.

David Pursell 8385fb299f libcutils: add multi-buffer socket send.
Unix and Windows both have functions to write multiple buffers to a
socket with a single call but they have very different signatures. This
CL creates some cross-platform functions to be able to perform these
operations in a uniform way, which will be required for upcoming
fastboot functionality.

This CL also fixes some inconsistent spacing in the touched files.

David Pursell 756e1c81e8 libcutils: add socket_get_local_port().
Tests that require a local server currently hardcode a test value,
which can run into conflicts depending on what's currently running on
the machine.

This CL adds socket_get_local_port(), which lets us pass 0 so the
system picks an open port and we can query which port it chose.

David Pursell 572bce2908 fastboot: use cutils socket functions.
Now that cutils has cross-platform socket functionality, we can
restructure fastboot to remove platform-dependent networking code.

This CL adds socket_set_receive_timeout() to libcutils and combines the
fastboot socket code into a single implementation. It also adds TCP
functionality to fastboot sockets, but nothing uses it yet except for
the unit tests. A future CL will add the TCP protocol which will use
this TCP socket implementation.

David Pursell 0eb8e1b706 libcutils: share Windows networking code.
This CL moves Windows networking code from fastboot to libcutils so
that it can be shared with other host programs such as adb.

Not all libcutils networking functions have been implemented for
Windows, just those necessary for fastboot. In the next CL I will do
the same for adb, adding any additional required functions.

Unit tests have also been added to test the functions using a loopback
connection.

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.

Mark Salyzyn 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.

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

Mark Salyzyn 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.

Nick Kralevich 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.
