Fix some warnings when compiling crashpad with VC++ 2015 Update 1.
Warning 4302 occurs if you convert from a pointer to a <sizeof(void*)
integer in one cast, because this often indicates an accidental pointer
truncation which can be a bug in 64-bit builds.
Warning 4577 warns that noexcept will not be enforced, but we don't want
it to be enforced anyway, so I disabled it. The full warning is:
warning C4577: 'noexcept' used with no exception handling mode specified
termination on exception is not guaranteed. Specify /EHsc

Patch from Bruce Dawson <brucedawson@chromium.org>.
This more-natural spelling doesn’t require Crashpad developers to have
to remember anything special when writing code in Crashpad. It’s easier
to grep for and it’s easier to remove the “compat” part when pre-C++11
libraries are no longer relevant.

MEMORY_BASIC_INFORMATION64 specifies an alignment of 16, but the
standard allocator used by containers doesn't honor this. Although 16
is the default alignment size used on Windows for x86_64, it's not for
32-bit x86. clang assumed that the alignment of the structure was as
declared, and used an SSE load sequence that required this alignment.
AlignedAllocator is a replacement for std::allocator that allows the
alignment to be specified. AlignedVector is an std::vector<> that uses
AlignedAllocator instead of std::allocator.

The BaseName() was added because system DLLs were being reported by
GetFileVersionInfo()/VerQueryValue() as having major file versions of
6.2 instead of 10.0 on Windows 10 when accessed by full path, but not
by BaseName(). The PEImageReader gets the correct version from the
in-memory images, 10.0.
This trick didn't work on Windows XP, where two copies of comctl32.dll
were found loaded into the process, one with a major file version of
5.82 and the other with 6.0. Giving GetFileVersionInfo() the BaseName()
would result in it returning information from one of these, which would
cause the version to not match when the PEImageReader was looking at the
other.
All of these GetFileVersionInfo() quirks make me glad that we're not
using it anymore (outside of the test).
Because of the version numbers involved (NT 6.2 = Windows 8, where
GetVersion()/GetVersionEx() start behaving differently for
non-manifested applications) and the fact that GetFileVersionInfo()
and VerQueryValue() seem to report 10.0 even with full paths on Windows
10 in applications manifested to run on that OS, the BaseName() thing is
restricted to Windows 8 and higher.

Don't call GetFileVersionInfo(), which calls LoadLibrary() to be able to
access the module's resources. Loading modules from the crashy process
into the handler process can cause trouble. The Crashpad handler
definitely doesn't want to run arbitrary modules' module initializer
code.
Since the VS_FIXEDFILEINFO needed is already in memory in the remote
process' address space, just access it from there.

On Win 7 in a debug configuration, walking all locks was gathering
hundreds of thousands of locks, causing test timeouts to be exceeded in
debug. On user machines, UnhandledExceptionHandler() could have timed
out too. For now, only grab the loader lock as it's the most interesting
one. Unfortunately, this means that !locks won't work for now.
In the future, we may want to figure out a signalling mechanism so that
the client can note other interesting locks to be grabbed, and just
avoid walking the list entirely.

On Win 7 in a debug configuration, this was gathering hundreds of
thousands of locks, causing test timeouts to be exceeded. On user
machines, UnhandledExceptionHandler() probably would have timed out
also. Arbitrarily cap the number of locks captured, as we don't have a
pressing need for anything other than the LoaderLock anyway.

FILE_TYPE_CHAR handles can't be inherited via
PROC_THREAD_ATTRIBUTE_HANDLE_LIST, or CreateProcess() fails with
GetLastError() == 1450 on Windows 7.
I confirmed that an fprintf(stderr, ...) in HandlerMain() does make it
to the console when running tests even after this.

This log spam from end_to_end_test.py indicated that
GetFileVersionInfo() was being called three times per module:
[3076:3424:20151123,102817.290:WARNING module_version.cc:29]
GetFileVersionInfoSize: ...\crashpad\out\Release_x64\crashy_program.exe:

The specified resource type cannot be found in the image file. (1813)
This is unnecessary. It only needs to be called once.
We may want to avoid logging in GetModuleVersionAndType() when
GetLastError() is ERROR_RESOURCE_TYPE_NOT_FOUND.

The bug and linked code review has more of the history, but we’ve been
tempted to remove the loop outright a couple of times already before
realizing that it serves an important purpose. Hopefully this comment
will protect our future selves from going on the same fool’s errand.

Previously, there was a window after starting the upload thread but
before the SIGTERM handler was installed, where receipt of SIGTERM
could have interrupted an in-progress upload. There was also the
possibility that a second SIGTERM sent after the exception handler
stopped running would interrupt an in-progress upload. By pulling the
signal handler out of ExceptionHandlerServer and into the main
function, these races are avoided.

I've heard/lived enough horror stories about AV, outbound-blocking
firewalls, etc. on Windows, that I think the best approach is to have
chrome.exe embed the majority of crashpad_handler and jump to it as
early as possible when running in that mode.
So, move most of crashpad_handler into a static_library with just main()
in the executable target.

In 2eeaa3ac549a, I added a check to make sure that the expected CONOUT$
handle was found. Its omission seemed to be unintentional. The tests
passed for me on Windows 10, but failed on the bots. I can reproduce
the failures locally on Windows 7.
Doing the inheritance test with a file other than CONOUT$ fixes the
immediate problem, but we should find out why this CONOUT$ handle isn't
showing up in the handles list on Windows 7, fix it, and add back a
test.
