7c6d2334a9 Don't fail minidump write if memory snapshot read fails
On Windows (and probably elsewhere) it's possible that something else on
the system changes the memory map between when a memory snapshot range
is added to the minidump, and when the process's memory is actually read
from the target and written to the .dmp file. As a result, failing the
Read() should not result in aborting the minidump's write, which it
previously would have.

6dac7ecdf5 Use constexpr at function scope
This is essentially based on a search for “^ *const [^*&]*=[^(]*$”

4b450c8137 test: Use (actual, [un]expected) in gtest {ASSERT,EXPECT}_{EQ,NE}
gtest used to require (expected, actual) ordering for arguments to
EXPECT_EQ and ASSERT_EQ, and in failed test assertions would identify
each side as “expected” or “actual.” Tests in Crashpad adhered to this
traditional ordering. After a gtest change in February 2016, it is now
agnostic with respect to the order of these arguments.

This change mechanically updates all uses of these macros to (actual,
expected) by reversing them. This provides consistency with our use of
the logging CHECK_EQ and DCHECK_EQ macros, and makes for better
readability by ordinary native speakers. The rough (but working!)
conversion tool is
https://chromium-review.googlesource.com/c/466727/1/rewrite_expectassert_eq.py,
and “git cl format” cleaned up its output.

EXPECT_NE and ASSERT_NE never had a preferred ordering. gtest never made
a judgment that one side or the other needed to provide an “unexpected”
value. Consequently, some code used (unexpected, actual) while other
code used (actual, unexpected). For consistency with the new EXPECT_EQ
and ASSERT_EQ usage, as well as consistency with CHECK_NE and DCHECK_NE,
this change also updates these use sites to (actual, unexpected) where
one side can be called “unexpected” as, for example, std::string::npos
can be. Unfortunately, this portion was a manual conversion.

c6f88d164e Have MinidumpMemoryListWriter deal directly in SnapshotMinidumpMemoryWriters
This is as a precursor to
https://chromium-review.googlesource.com/374539 which merges
MemorySnapshots and so needs to be able to update them from the minidump
code.

MinidumpMemoryWriter existed to be able to mock for tests; that
behaviour is wrapped up in TestMemorySnapshot now.

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.
