This extracts the existing objdump-based disassembler engine used in
ExploitabilityLinux into a seperate reusable class, and adds support
for most common address operand formats.
This is a precursor to using DisassemblerObjdump to handle address
resolution for non-canonical address dereferences on amd64.

Doing a `make -jN check` from a fresh build breaks (and has probably been
broken for a while). linux_client_unittest_shlib is missing $(TEST_LIBS)
from its _DEPENDENCIES. The automake manual says if _DEPENDENCIES are not
specified they'll be computed from _LDADD, but we are specifying it and just
leaving out $(TEST_LIBS).

Review URL: https://codereview.chromium.org/1870733005 .
This adds a minimalistic implementation of getcontext()
for Android/ARM and Android/x86. The provided code is
in assembly and only implements the bare minimum required
by Breakpad to get the current processor state.
Note that:
- The FPU state is not saved to the ucontext_t on ARM.
(that's actually the main difference with a normal
getcontext() implementation).
This is normal. On Linux/ARM, such state must be
obtained with PTRACE_GETVFPREGS instead. This will
be implemented in a future patch.
- On x86, only the 'regular' FPU state is saved, to
mimic the GLibc/i386 implementation. The state of
SSE/SSE2/etc registers is not part of the upstream
getcontext() implementation.

is no reason not to keep it locally. Implemented a basic disassembler which can be used
to scan bytecode for interesting conditions. This should be pretty easy to add to for
things other than exploitability if there is a desire. This also adds several tests to
the windows exploitability ranking code to take advantage of the disassembler for x86
code.

- Introduces a standard API for dealing with modules. MinidumpModule
is now a concrete implementation of this API. Code may interact with
single modules using the CodeModule interface, and collections of
modules using its container, the CodeModules interface.
- CodeModule is used directly by SymbolSupplier implementations and
SourceLineResolver. Reliance on the specific implementation in
MinidumpModule has been eliminated.
- Module lists are now added to ProcessState objects. Module references
in each stack frame are now pointers to objects in these module lists.
- The sample minidump_stackwalk tool prints the module list after printing
all threads' stacks.

- Eliminate MemAddrMap from source_line_resolver.cc and adapt it to use
RangeMap, also used by minidump.cc.
- RangeMap operates on both a base address and a size, where MemAddrMap

to include size information. dump_syms produces these files and
SourceLineResolver consumes them.
- Provide updated test data conforming to the new dumped symbol format.
