Mark Salyzyn cfd5b080af system/core: preparation to pull back interfaces from android/log.h
Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Correct liblog/README

Effectively a cleanup and controlled select revert of
'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Test: compile

Mark Salyzyn ff2dcd9af9 system/core Replace log/log.h with android/log.h
Should use android/log.h instead of log/log.h as a good example
to all others.  Adjust header order to comply with Android Coding
standards.

Josh Gao f5a960a187 debuggerd: remove useless timeout from wait_for_signal.
The watchdog already handles things for us, so the timeout logic in
wait_for_signal is pointless.

Christopher Ferris 99235e9967 Fix problem with wait_for_gdb.
When someone enables wait_for_gdb, activity manager will kill the
stopped process before a developer can attach to the process. To
allow debugging in this case, change the code to only contact the
activity manager right before continuing the process that is
crashing.

Also, modify the conditions under which to do a gdb attach. The previous
code did a partial attach if perform_dump failed. The new version simply
allows an attach regardless of whether perform_dump passes or fails.

Josh Gao 7c89f9e955 debuggerd: fix several bugs caused by fork/setuid change.
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.

Christopher Ferris 456abbabf2 Dump memory going from unreadable to readable.
If the first read when dumping memory returns no data, skip ahead to
the next page boundary and try and read from there. This fixes a case
where the address at which to start dumping memory is unreadable, but
crosses back into readable memory.

Christopher Ferris b36b592338 Replace all _LOG error calls with ALOGE.
The debuggerd code sometimes calls _LOG(..., logtype::ERROR, ...)
and sometimes ALOGE(). Standardize on ALOGE since the _LOG message
will wind up in the tombstone in weird places, but using ALOGE
will wind up in the logcat portion of the tombstone.

Christopher Ferris e8bc77eb84 Refactor dump_memory function.
- Add dumping memory around registers for x86/x86_64.
- Add unit tests for new dump_memory function.
- Cleanup all of the machine.cpp files.
- Increase the high address check for 32 bit, and decrease the high
  address allowed for 64 bit slightly to match mips64.

This avoids the log daemon skipping some of the log output from
debuggerd.

Christopher Ferris 1072f917cf Fix debuggerd issues.
- Fix a problem where a tid exits before the attach completes, and it
  causes debuggerd to self terminate.
- Fix a problem where sibling tid dumps do not properly wait for the tid
  to get signalled.

Brigid Smith 50eb546ec1 Removed log.quiet and log = NULL cases from debuggerd.
Now the functionality implemented by these semi-confusing cases has been
replaced with the same logtype enum behavior that is easier to
understand, and cases that used log-looking behavior to print to logcat
(when log = NULL) now use the more transparent ALOGE/ALOGD functions.

Brigid Smith 62ba489ba0 Changing how debuggerd filters log messages to different locations.
The system by which debuggerd filters its output to different locations
is now based on an enum called logtype with easy to understand
categories for log messages (like THREAD, MEMORY, etc.) instead of the
old, fairly esoteric scope_flags variable.  Now much of the output that
previously went to logcat does not show up on the screen, but all output
can be found in the tombstone file.  In addition, the tombstone's
location is now printed so it can be located easily.

Kévin PETIT 4bb477205a debuggerd: a few generic improvements
This one makes dump_memory reasonably architecture-agnostic so it is
possible to share the code between architectures.

It also includes a few small improvements in tombstone.cpp.

Christopher Ferris 20303f856f Next phase of the move, reformat use C++ features.
Use the libbacktrace C++ interface instead of the C interface in debuggerd.

Reformat the debuggerd code to be closer to Google C++ style.

Fix all debuggerd casts to be C++ casts.

Add a frame number to the frame data structure for ease of formatting and
add another FormatFrameData function.

Change the format_test to use the new FormatFrameData function.

Modify all of the backtrace_test to use the C++ interface.

Christopher Ferris d607495b89 Move to C++ for debuggerd.
This is part 1, only including the bare minimum changes because
our diff tool doesn't easily show differences when a file moves. This
also breaks it into a small chunk in case some other changes break things,
as unlikely as I think that will be.
