metrics
for GMS devices.

Don't spend CPU cycles formatting a bunch of strings if we're
just going to throw them away later. Maybe make booting faster.

The check_unreadble_elf_* tests only create a readable map. I changed
libunwind to disallow unwinding through non-executable maps, so make
the maps executable too.

Also, fix bugs that this uncovered. In particular, the sysdeps_win32
FATAL macro would only print __FUNCTION__.

The actual maximum length will depend on the version of the shell
protocol being used, and any additional parameters being passed through
(e.g. TERM=xterm-256color). This should be able to be raised to 64K for
devices with commit 3d2904c (L-MR1 and above), but that'll require some
plumbing.

Add a README describing the basic functionality and configuration
of crash_reporter. Also include some development tips based on
feedback from users.

Previously, we weren't PTRACE_ATTACHing to all of the threads of a
process, and we were also trying to do it after forking and dropping
privileges. This patch ensures that all ptrace attaching/detaching
happens in one place, before forking/exiting respectively.

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.

Every now and then (5 minutes by default), the uploader will persist the
current metrics to disk to avoid losing them in case we exit
unexpectedly (reboot or crash).
When starting up, metricsd will load the previously saved log and resume
the metrics collection from there.
Bug: 25670584
Test: Unit tests.
Test: manual: restart metricsd. The saved log is detected and parsed
correctly.
Test: manual: Send a sample to metricsd, send SIGTERM to metricsd, the
log is saved to disk, metricsd restarts and picks up the log where it
left.

metricsd should shutdown cleanly when receiving a TERM signal:
* stop the binder watcher.
* wait for the thread to quit.
* Exit cleanly.
Note: This is not directly used as we don't send SIGTERM on shutdown or
when stopping services yet.

Currently one of the udev collector tests is failing due to the lack
of gzip on the device. Since we don't have gzip nor udev in Android builds,
remove the udev collector (and tests) from Android builds.
See http://r.android.com/184708 for discussion on removing the udev
collector completely from the source.

Without this change LogBuffer::prune and LogBuffer::erase
contributes 16.7% and 1.79% respectively. With this change,
they contributes 3.06 and 2.33% respectively. Pruning is
performed roughly 1 in every 255 log entries, a periodic
tamer latency spike.

Currently, properties that begin with "ro." are special cased to skip
over the "ro." part of the prefix before matching with entries in
property_contexts. This is not strictly needed however and it is
causing complications with the separated prop files work from Bug
21852512, so it is now removed.
