07fcf63c21 win: fixes for Windows x64
Mostly size_t <-> unsigned int warnings, but I also had a mistake in
PROCESS_BASIC_INFORMATION, the pids are 32-on-32 and 64-on-64.

The Windows build is still x86 until https://codereview.chromium.org/981333002/.
I don't think I'll bother maintaining the x86 build for now, though we will probably
need it for x86 OSs in the future. It should be straightforward to revive it once we
need it, and have bots to support it.

79177046d3 Mac 10.6 SDK compatibility.
A couple of the problems related to not having a C++11 library:

 - You can’t put const elements into a std::vector<>, so
   CrashReportDatabase::GetPendingReports() and
   CrashReportDatabase::GetCompletedReports() need to change. There was
   no data-safety benefit to const elements.
 - std::string::pop_back() does not exist, another mechanism must be
   used to trim strings in BreakpadHTTPFormParametersFromMinidump().

One relates to a feature that does not exist in 10.6:

 - The O_CLOEXEC flag to open() was introduced in 10.7. Although it
   would be possible to use fcntl(..., F_SETFD, FD_CLOEXEC) on 10.6, the
   O_CLOEXEC behavior is just removed from
   CrashReportDatabaseMac::ObtainReportLock(), in line with other open()
   calls in Crashpad.

And one was a real bug:

 - #define __STDC_FORMAT_MACROS before #including <inttypes.h> to get
   format macros like SCNx32, used in UUID::InitializeFromString().

bd77b3034f win: Implementation of CrashReportDatabase for Windows (for C++ Windows readability review)
Original CL (review, misc support code changes) at https://codereview.chromium.org/867363003/.

Crashpad is a component of Chrome used for capturing crashes in the field and uploading them to crash/ for analysis: https://code.google.com/p/crashpad/.

0849154aed win: Implementation of CrashReportDatabase for Windows
As there are no extended file attributes available on all Windows file
systems (NTFS supports alternate data streams, but Chrome still supports
running on FAT), instead of using metadata attached to the file, metadata
is stored separately in a simple record-based file and keyed by UUID.

Initially, I attempted a metadata file beside each report, each locked
separately more closely mirroring the Mac implementation. But given the
expected number of of active reports (in the 10s to 100s range?) and the
size of the metadata for each, simply storing it all in one file is much
less complicated when considering error situations.

If the serialization/deserialization becomes a measurable problem, it
could be optimized at some complexity by reading/writing only as
necessary, or optimizing the storage.
