329ed7dae4 Add load base to map for relocation packing.
The new linker relocation packing support uses non-zero load bases,
so we better handle them properly.

Also print out the load base for a map if it's non-zero.

2c43cff01d Refactor the code.
The object hierarchy was confusing and convoluted. This removes
a lot of unnecessary code, and consolidates the BacktraceCurrent
and BacktraceThread code into BacktraceCurrent.

12385e3ad0 Move map data into backtrace data proper.
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.

ac2fe7eb81 Add missing headers
These headers are needed for pid_t and free when using libc++ headers (POSIX
does not require that the symbols be exposed with the previous includes).

e296091060 Create an UnwindMapLocal object.
The way libunwind handles local unwinds is different from remote unwinds,
so create a new map object to handle the differences.

Add new test to verify the map data is being generated correctly.

Add new tests to check for leaks.

Refactor the BACK_LOGW code into a single header file.
