dd85381a32 GCC fix: Disable -Wmultichar warning throughout Crashpad
-Wmultichar is enabled by default with GCC (but not clang). It is
impossible to disable this warning with #pragma GCC diagnostic ignored.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431

While compiling, for example, minidump_file_writer.cc:

In file included from ../../minidump/minidump_extensions.h:25:0,
                 from ../../minidump/minidump_file_writer.h:27,

../../util/misc/pdb_structures.h:45:38: error: multi-character character constan
t [-Werror=multichar]
   static const uint32_t kSignature = '01BN';
                                      ^~~~~~

constant [-Werror=multichar]
   header_.Signature = MINIDUMP_SIGNATURE;
                       ^~~~~~~~~~~~~~~~~~

doc/developing.md is also updated to provide GCC build instructions for
Android.

Tested with:
 - GCC 4.9 from NDK r13 targeting arm with SDK 16
 - GCC 4.9 from NDK r13 targeting arm64 with SDK 21
 - GCC 6.2 targeting x86_64

e18f6a6e66 Nest crashpad and mini_chromum deeper in the external-dependencies build
crashpad and mini_chromium both have top-level “build” directories.
These would conflict with top-level “BUILD” files in google3 when
checked out on a case-sensitive filesystem. Although Crashpad’s “build”
directory can be moved easily, mini_chromium’s matches Chromium’s, which
is much more difficult to move. “build” is also the best and most
obvious name for these directories.

To avoid this problem, in the external-dependencies build, crashpad and
mini_chromium are placed one level deeper, just as crashpad is in
Chromium, and mini_chromium is in the standalone Crashpad build. This
allows true pristine unmodified copies to be checked in to google3,
without comingling locally-added files such as BUILD with external
source.

The directory structure adopted for the external-dependencies build is
now

      root/crashpad/crashpad[/README]
      root/gmock[/include/gmock/gmock.h]
      root/gtest[/include/gtest/gtest.h]
      root/gyp[/pylib/gyp]
      root/mini_chromium/mini_chromium[/build/common.gypi]

88eea80ad3 Add an “external” mode for obtaining dependencies
This augments the standalone and in-Chromium models with an external
model, in which the dependencies and Crashpad are checked out as
siblings in the same directory, organized according to this structure:

  root/crashpad[/README]
  root/gmock[/include/gmock/gmock.h]
  root/gtest[/include/gtest/gtest.h]
  root/gyp[/pylib/gyp]
  root/mini_chromium[/build/common.gypi]

This is the directory structure used in google3.

I'd like to write some `expect(1)`-style tests (possibly using
http://pexpect.readthedocs.org/en/stable/) to verify that various windbg
commands that I'm adding support for do actually work when consuming
minidumps in real life.

For the moment, this is just the beginnings of a stub as I don't know if
bots even have windbg/cdb installed.

bf556829d9 win: support x64 reading x86 (wow64)
Removes the bitness-specific targets in favour of pulling binaries from
the other build directory. This is to avoid the added complexity of
duplicating all the targets for the x86 in x64 build.

Overall, mostly templatizing more functions to support the
wow64-flavoured structures. The only additional functionality required
is reading the x86 TEB that's chained from the x64 TEB when running
as WOW64.

The crashing child test was switched to a manual CreateProcess because
it needs to launch a binary other than itself.

6978bf7646 win: Crash handler server
This replaces the registration server, and adds dispatch to a delegate
on crash requests.

(As you are already aware) we went around in circles on trying to come
up with a slightly-too-fancy threading design. All of them seemed to
have problems when it comes to out of order events, and orderly
shutdown, so I've gone back to something not-too-fancy.

Two named pipe instances (that clients connect to) are created. These
are used only for registration (which should take <1ms), so 2 should be
sufficient to avoid any waits. When a client registers, we duplicate
an event to it, which is used to signal when it wants a dump taken.

The server registers threadpool waits on that event, and also on the
process handle (which will be signalled when the client process exits).
These requests (in particular the taking of the dump) are serviced
on the threadpool, which avoids us needing to manage those threads,
but still allows parallelism in taking dumps. On process termination,
we use an IO Completion Port to post a message back to the main thread
to request cleanup. This complexity is necessary so that we can
unregister the threadpool waits without being on the threadpool, which
we need to do synchronously so that we can be sure that no further
callbacks will execute (and expect to have the client data around
still).

In a followup, I will readd support for DumpWithoutCrashing -- I don't
think it will be too difficult now that we have an orderly way to
clean up client records in the server.

809ea8158d test: Move util/test to its own top-level directory, test.
After 9e79ea1da719, it no longer makes sense for crashpad_util_test_lib
to “hide” in util/util_test.gyp. All of util/test is moved to its own
top-level directory, test, which all other test code is allowed to
depend on. test, too, is allowed to depend on all other non-test code.

In a future change, when crashpad_util_test_lib gains a dependency on
crashpad_client, it won’t look so weird for something in util (even
though it’s in util/test) to depend on something in client, because the
thing that needs to depend on client will live in test, not util.

b665a0db07 Allow Crashpad to build in the Chromium tree.
When building in the Chromium tree, this swaps out Crashpad’s copies of
mini_chromium, gtest, and gmock for the equivalents provided by
Chromium. A GYP variable, crashpad_in_chromium, is used to determine the
behavior.

gclient doesn’t sync sub-DEPS, so when doing an in-Chromium build,
Crashpad’s copies of mini_chromium, gtest, and gmock are not available.

32a9d410ca Locate test data more robustly.
Test code that requires test data should call Paths::TestDataRoot() to
obtain the test data root. This will use the CRASHPAD_TEST_DATA_ROOT
environment variable if set. Otherwise, it will look for test data at
known locations relative to the executable path. If the test data is not
found in any of these locations, it falls back to using the working
directory, the same as the current behavior.

b256df0534 Set target_name on many targets to use a crashpad_ prefix.
In Chromium, many targets are built, sharing a single output directory.
Collisions are likely. When integrating Crashpad into Chromium, the
ui/snapshot library and Crashpad’s snapshot library were found to
conflict.

This change gives most Crashpad targets a “crashpad_” prefix to avoid
conflicts. All library and test targets are given a target_name with
this prefix. Existing tools are not likely to conflict with anything
else and are not given a prefix.

b770a51f2b Set the chromium_code GYP variable.
When building in the Chromium tree, chromium_code is necessary to apply
Chromium’s build/filename_rules.gypi. Crashpad’s build depends on these
rules. chromium_code also enables a high warning level, which is
desirable for Crashpad.
