These two exception types use all 64 bits of the code[0] field. The
ExceptionSnapshot was unprepared to stuff this into a 32-bit field. To
resolve the discrepancy, the more-significant data is taken from the
high 32 bits of code[0]. No information is lost because the full code[0]
is made available as part of the Codes() vector.

The wiki existed at https://code.google.com/p/crashpad/wiki, but given
Google Code Project Hosting’s impending shutdown[1], it’s prudent to
move wiki documents into the source code repository.
This change moves the existing contents of doc into doc/support, to make
way for documentation in doc. The two existing wiki pages, ProjectStatus
and DevelopingCrashpad, are converted to AsciiDoc format (a fairly
straightforward conversion) and checked in to doc. generate_asciidoc.sh
is updated to produce HTML output from these files. The generated HTML
will show up at http://docs.crashpad.googlecode.com/git/doc/. Note that
generated HTML is still hosted on Google Code Project Hosting, but it’ll
be easy to find a new home for them.

ExcServerCopyState() properly sets the new_state and new_state_count
out-parameters for exception handler routines that may deal with
state-carrying exceptions.
This used to exist inline in catch_exception_tool, but that
implementation had a bug caught by the new 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.

In a future change, crashpad_util_test_lib will gain a dependency on
crashpad_client. This would violate GYP’s prohibition on circular
dependencies between .gyp files, although there would be no circular
relationship between the targets themselves. To overcome this problem,
all test-related targets are moved into their own first-class .gyp
files.

Add MapInsertOrReplace<>() to insert a key-value pair into a map if the
key is not already present, or replace the existing value for key if the
key is present. The original value can optionally be returned to the
caller in this case.
Map insertions now use either MapInsertOrReplace<>() or
std::map<>::insert() directly.
Use MapInsertOrReplace<>() when the map should be updated to contain a
mapping from a key to a value regardless of whether the key is already
present.
Use std::map<>::insert() to insert a mapping from a key to a value
without replacing any existing mapping from a key, if present. If it is
important to know whether an existing mapping from a key was present,
use the returned std::pair<>.second. If it is important to know the
existing value, use the returned std::pair<>.first->second.
This change has a slight positive impact on performance.

The new call is also used in
CrashReportDatabaseWin::PrepareNewCrashReport(). Previously, that method
used the UUID::InitializeFromBytes() constructor. That actually caused
various fields of the UUID to be byte-swapped so that the ::UUID and
crashpad::UUID would be different UUIDs. Although a UUID is mostly
random, the version field in data_3 is used as a namespace and should be
4 for random UUIDs, and this was not the case under swapping.

Now that Chrome’s about:crashes displays the crash report UUID, I wanted
to add it to the minidump. In the future, we may be able to index these
on the server. This will also help identify dumps that correspond to the
same event once we’re equipped to convert between different formats.
Ideally, this new field is populated with the same UUID used locally in
the crash report database. To make this work,
CrashReportDatabase::NewReport must carry the UUID. This was actually
part of CrashReportDatabaseWin’s private extension to NewReport, so that
extension subclass can now be cleaned up.

This regressed in 359bdd86225c when a non-POD UUID data member was added
to MinidumpCrashpadInfo, which made MinidumpCrashpadInfo non-POD. This
problem seems to have affected MinidumpModuleCodeViewRecordPDB70 since
it was added, but it is not likely to have caused any problems there
because that structure never appears without having all of its members
populated. By comparison, MinidumpCrashpadInfo may be sparsely
populated.
This caused 4 of the 5 MinidumpCrashpadInfoWriter tests to fail on
Windows.

The client ID is added to a new field, MinidumpCrashpadInfo::client_id,
in each minidump file that is written. The ProcessSnapshot::ClientID()
gives access to value at the snapshot level. In the upload thread,
client IDs are retrieved from minidump files and used to populate the
“guid” HTTP form parameter.
The Breakpad client supplies these values at upload without hyphens and
with all capital letters. Currently, the Crashpad client uses hyphens
and lowercase letters when communicating with a Breakpad server.

ClientInfo::set_system_crash_reporter_forwarding() can be used to
disable forwarding. The first module that is found with a non-default
value in this field will dictate whether forwarding is enabled or
disabled. It is possible to enable or disable reporting with this call,
as well as reset it to default, which will allow later modules a chance
to influence the behavior.
ClientInfo::set_crashpad_handler_behavior() is also provided, which can
be used to disable Crashpad’s handling of the exception. Most users
should not call this, but should use Settings::SetUploadsEnabled()
instead.

NSInputStream requires overriding and implementing private methods in order to
use it with NSURLConnection [1]. It is cleaner to use the private but stable
and open source CFStreamAbstract.h header from CF-Lite to implement a
CFReadStream. Since CFReadStream is toll-free bridged to NSInputStream, the
remainder of the HTTPTransport code can remain unchanged.

Rather than accepting the path to the database’s parent directory, this
now accepts the path to the database itself. Using the parent directory
proved cumbersome in practice. When testing crashpad_handler with a
variety of databases, it is useful to be able to specify
--database=/tmp/crashpad_database, --database=/tmp/crashpad_database_2,
etc. The old interface required that these directories be created as a
separate step, and would put the actual database at
/tmp/crashpad_database/Crashpad. This was contrary to the operation of
most tools and interfaces, which would only require that /tmp exist and
would put the database at /tmp/crashpad_database.
