Fix two races in debuggerd's PTRACE_ATTACH logic:
1. The target thread in a crash dump request could exit between the
/proc/<pid>/task/<tid> check and the PTRACE_ATTACH.
2. Sibling threads could exit between listing /proc/<pid>/task and the
PTRACE_ATTACH.

Keeping these means that every build has different init and debuggerd
binaries, even if the source was the same. So OTAs that don't touch
these sources would still need to update the binaries.
Both of these messages are only informational, so can be safely removed.
Bootchart already encodes build-specific information from the system
properties.

Let CyanogenMod developers know of a Cyanogen enhancement made by
Clark Scheff and Steve Kondik where the graphical debugger
interface ddd can be used with crashed applications. The new in-line
function, dddclient, is now available in addition to the std Google
gdbclient interface.
Also, let users know that they have set their property debug.db.uid
too low to enable debuggerd to wait for gdb to attach.
If they haven't set debug.db.uid; let them know; and offer a hint
on how to do it, without their having to Google for the web page.

Previously, the map printing in tombstones for 64 bit devices uses
a variable length value. This means that the maps are not lined up.
The new format is to print the map as 00000000'00000000 in all ways.
Also fix a bug where the backtrace_map_t did not initialize all
parameters.
Add unit tests for all of the dump_all_maps 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.

Under some conditions, /proc/<pid>/maps might return nothing. If we
try and unwind in this case, we'll crash. Check this case and fail
the unwind.
Add checks that no other functions try and use map_ without
checking for nullptr.
Add logging when an unwind fails so it's clear what happened.

The new linker relocation packing support uses non-zero load bases,
so we better handle them properly.

ELF said that padding is present, if necessary, to ensure 4-byte
alignment for the descriptor and next note entry, but such padding
is not included in namesz and descsz.

Move away from using POSIX open(2) flags and introduce ANDROID_LOG_* flags to
replace them. Add security by preventing random mode flags from getting into
underlying POSIX calls. ANDROID_LOG_* flags overlap POSIX O_* flag definitions.

Modifies the code so that if the unwind fails, the code still prints
as much data as possible.
Also, for sibling threads, skip printing the maps and memory/code
since it's not likely to be very relevant.
Fix a few cases where extra space is at the end of lines.
Fix an inverted if statement that was checking the wrong condition.

The backtrace structure used to include a pointer to a backtrace_map_t
that represented the map data for a particular pc. This introduced a
race condition where the pointer could be discarded, but the backtrace
structure still contained a pointer to garbage memory. Now all of the map
information is right in the structure.

On 64 bit systems, calls to dump_backtrace_to_file or dump_tombstone
try and directly contact the correct debuggerd (32 bit vs 64 bit)
by reading the elf information for the executable.
Unfortunately, system_server makes a call to dump_backtrace_to_file
and it doesn't have permissions to read the executable data, so it
defaults to always contacting the 64 bit debuggerd.
This CL changes the code so that all dump requests go to the 64 bit
debuggerd, which reads the elf information and redirects requests for
32 bit processes to the 32 bit debuggerd.
Testing:
- Forced the watchdog code in system_server to dump stacks and
verified that all native stacks are dumped correctly.
- Verified that dumpstate and bugreport still properly dump the native
processes on a 64 bit and 32 bit system.
- Intentionally forced the 64 bit to 32 bit redirect to write only a
byte at a time and verified there are no errors, and no dropped data.
- Used debuggerd and debuggerd64 to dump 32 bit and 64 bit processes
seemlessly.
- Used debuggerd on a 32 bit system to dump native stacks.
