Elliott Hughes da6b2e2fd7 Improve liblog's fatal logging.
This makes LOG_ALWAYS_FATAL and LOG_ALWAYS_FATAL_IF as good as regular
assert(3).

Elliott Hughes 6694d3e3d5 Remove dead code that looked like part of debuggerd.
Note that these were two different functions. The definition was unused,
and the declaration was undefined.

Elliott Hughes b1be27e29b Improve the crasher stack-overflow command.
Runs a lot quicker, with no intermediate noise.

Elliott Hughes 6f40cafd9f Add a new test to crasher to upset dlmalloc.
We should also add a test for heap corruption, but I failed to come up
with a kind of corruption that dlmalloc actually detects (rather than
just crashing accidentally).

Pavel Chupin af2cb3667b Unwinding implementation via eh_frame sections for x86
Backtracing through eh_frame section is more effective allowing to reuse
ebp register for other purposes within routine. GCC with turned on
optimizations (-O1 and above) implicitly defines -fomit-frame-pointer
anyway. eh_frame sections are generated by default with GCC on any
optimization level.

This change implements remote unwinding (separate process unwinding).
Local unwinding is already implemented through _Unwind_Backtrace call
which is implemented in libgcc.

Elliott Hughes df4200e8c2 Add a "smash-stack" option to crasher.
bionic's __stack_chk_fail was preventing debuggerd from dumping
stacks, which was not helpful.

Elliott Hughes aa4213057b Expand crasher with a "thread-" prefix to crash on another thread.
So "thread-nostack" runs the "nostack" code on a new thread, and
"thread-abort" runs the "abort" code on a new thread, and so on.
