This CL hits lots of source files because:
1. An update to the CodeModule virtual class. I added an is_loaded
method to specify whether the module is loaded. There were several
mocks/test classes that needed to be updated with an implementation.
An alternative to this route would be to modify
MinidumpUnloadedModule::code_file to prepend "Unloaded_" to the
module name.
2. Added an unloaded_modules parameter to
StackFrameSymbolizer::FillSourceLineInfo.

and updating minidump_stackwalk to show process uptime.
I tested this with a minidump from Chrome and I got a result that
is inline with what the Windows debugger is showing for that dump:
minidump_stackwalk output:
--------------------------
Process uptime: 601 seconds
WinDBG output:
--------------
Process Uptime: 0 days 0:10:01.000
I didn't update the machine readable output of minidump_stackwalk
on purpose in order to avoid breaking someone that uses it.
It can be added later to the machine output if needed.

errors and use the good data if possible.
More specifically:
- Detect corrupt symbols during minidump processing and provide the list of modules with corrupt symbols in the ProcessState. This will allow listing the corrupt symbol files in the final crash report.
- Skip and recover from symbol data parse errors - don't give up until 100 parse errors are seen.
- In order to recover from '\0' (null terminator) in the middle of a symbol file, a couple of methods have to be updated to require both buffer pointer and length. Previously they required only a buffer pointer (char *) and the size of the buffer was evaluated using strlen which is not reliable when the data is corrupt. Most of the changes are due to these signature updates.
- Added and updated unittests.
Also, updated minidump_stackwalk to show a WARNING for corrupt symbols. Output looks like this:

Interface change: moved a few fields around in ProcessState; added new
arguments to Stackwalker and SymbolSupplier.

- 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.

- MinidumpProcessor now processes all threads and returns a new ProcessState
object. (Interface change.)
- ProcessState contains a CallStack for each thread in the process, and
additional information about whether the process crashed, which thread
crashed, the reason for the crash, and identifying attributes for the
OS and CPU.
- MinidumpSystemInfo now contains a GetCPUVendor() method that returns the
vendor information from CPUID 0 on x86 processors ("GenuineIntel").
