Show the number of VMAs in the tombstone.
Tombstones (especially ones with lots of VMAs) are regularly truncated.
We can at least show the number of VMAs, though, for anyone interested
in knowing whether they got close to the default 64Ki limit.

Bug: 64709603 (presubmit balking at the line above)
Test: ran crasher, examined tombstone

Cleanup the libbacktrace interface a bit.
- Change the field name load_base to load_bias (which is what it really is).
- Add a rel_pc field so that callers do not need to compute it themselves.
- Remove the BacktraceMap::GetRelativePc() since nobody should need to
compute this themselves.
Bug: 23762183
Test: Compiles and unit tests pass (debuggerd, libbacktrace).

Decode ptrace-induced SIGTRAP si_code values.
Example:
signal 5 (SIGTRAP), code -32763 (PTRACE_EVENT_STOP), fault addr 0x274e00005fb3
I'm tempted to say that %d isn't the best choice for si_code, but as long as
we're fully decoding all the values, I don't think it matters.

Do not access device maps.
It's possible that a device map has memory controlled by a single entry
device driver. Thus, you can deadlock if a process is touching that
device memory and we try to unwind it and also touch that device memory.
Simply skip any attempts to step through, or get function names from
device memory maps.
Bug: 36130325
Test: Ran new unit tests, ran bionic unit tests, ran art ThreadStress.

crash_dump: fetch process/thread names before dropping privileges.
Processes that don't have dumpable set to 1 cannot have their
process/thread names read by processes that don't have all of their
capabilities. Fetch these names in crash_dump before dropping
privileges.
