892c29e8ba Reorganize Multiprocess and implement for Windows
- Various "FD" to "Handle"
- Existing Multiprocess implementation moves to _posix.
- Stub implementation for _win.

At the moment, multiprocess_exec_win.cc contains implementations of both
Multiprocess methods and MultiprocessExec functions. This will need more
work in the future, but reflects the idea that all tests should be in
terms of MultiprocessExec eventually.

Currently, this works sufficiently to have util_test succeed (including
multiprocess_exec_test, and the recently ported HTTPTransport tests.)

10165ce449 Cross platform low level file IO wrappers
Rename fd_io to file_io, and ReadFD to ReadFile, etc.

file_io.cc is the higher level versions that call the basic ReadFile/WriteFile
and then file_io_posix.cc and file_io_win.cc are the implementations of
those functions.

The Windows path is as yet untested, lacking the ability to link the test binary.

a02f721637 Add NewMachPort() and its test, and switch call sites to use it.
There were many call sites that wasted a few lines on
mach_port_allocate() and sticking the result into a scoper. I was about
to add three more, so I took the opportunity to simplify things.

48b1964d1b Use implicit_cast<> instead of static_cast<> whenever possible.
implicit_cast<> only performs a cast in cases where an implicit
conversion would be possible. It’s even safer than static_cast<> It’s an
“explicit implicit” cast, which is not normally necsesary, but is
frequently required when working with the ?: operator, functions like
std::min() and std::max(), and logging and testing macros.

The public style guide does not mention implicit_cast<> only because it
is not part of the standard library, but would otherwise require it in
these situations. Since base does provide implicit_cast<>, it should be
used whenever possible.

The only uses of static_cast<> not converted to implicit_cast<> are
those that require static_cast<>, such as those that assign an integer
constant to a variable of an enum type.

525de2c35a Use exactly one of final, override, and virtual.
This change was generated mechanically by running:

  find . \
      \( -name \*.cc -or -name \*.mm -or -name \*.h \) \
      -and -not -path ./third_party/\* -and -not -path ./out/\* -exec \

      -and -not -path ./third_party/\* -and -not -path ./out/\* -exec \
      sed -i '' -E -e 's/virtual (.*) override/\1 override/' {} +

Additional changes were made manually based on:

  git grep -E '^ {3,}.*override[;{]'

5d74f120fc Convert NULL to nullptr.
This change was generated mechanically by running:

  find . \( -name \*.cc -or -name \*.mm -or -name \*.h \) \
      -and -not -path ./third_party/\* -and -not -path ./out/\* \
      -exec sed -i '' -E -e 's/(^|[^_])NULL/\1nullptr/g' {} +

Further manual fix-ups were applied to remove casts of nullptr to other
pointer types where possible, to preserve the intentional use of NULL
(as a short form of MACH_PORT_NULL) in exception_port_tool, and to fix
80-column violations.

8c7872e9e0 Use the correct null constants for Mach threads, tasks, and hosts.
This uses THREAD_NULL, TASK_NULL, and HOST_NULL in preference to
MACH_PORT_NULL and kMachPortNull. These constants are correctly-typed
(thread_t, task_t, and host_t) and result in more readable source code,
especially where thread and task parameters appear together as they do
in exc_*_variants.

22350bd676 In tests, use ASSERT_NO_FATAL_FAILURE() instead of checking
testing::Test::HasFatalFailure() after calling functions that could fail
fatally.

c93fcf8278 In MachMultiprocess-based tests, the child must wait for the parent to
finish.

It was possible for the child process to exit before the parent had a
chance to complete the pid_for_task() portion of its verification.

4d35ffa80e Use more-specific typedefs for send rights to task, thread, and
exception handler ports.

task_t, thread_t, and exception_handler_t are typedefs for mach_port_t.
They are more descriptive than mach_port_t, and are already in use in
exc_server_variants.

4004e77ee9 Improvements for MachMultiprocess.
This adds a pipe going in the other direction (parent to child).
Initially, I didn’t think this was necessary, but it turned out to be
needed for ProcessReader. Having the child wait on a pipe read is the
easiest way to keep it alive until the parent is done with it.

This also tests MachMultiprocess::ChildPID() in
mach_multiprocess_test.cc.

Both of these fell out of https://codereview.chromium.org/491963002/.
