nullptr ProcessReader::Module.
Prior to 64b87325b9de, the alignment problem meant that the Module for
dyld was looking at the wrong address instead of dyld’s correct load
address when a 32-bit process attempted to examine a crashing 64-bit
process. This resulted in a crash during the
MachOImageAnnotationsReader.CrashDyld test.
ProcessReader::Module pointers are permitted to be nullptr. This allows
minimal module data (its name) to be preserved even when no sense can be
made of the module based on its load address. The producer,
ProcessReader::InitializeModules(), and the non-test consumer,
ModuleSnapshotMac::Initialize(), both accept this correctly. The
producer’s documentation is updated to call this out. The ProcessReader
test is also updated to tolerate this case without crashing by adding
assertions.

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.

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().

This is as a precursor to ProcessReader. Some basic functionality
is included for now, with more to be added later as necessary.
The PEB code is pretty icky -- walking the doubly-linked list
in the target's address space is cumbersome. The alternative
is to use EnumProcessModules. That would work but:
1) needs different APIs for XP and Vista 64+
2) retrieves modules in memory-location order, rather than
initialization order. I felt retrieving them in initialization order
might be useful when detecting third party DLL injections. In the
end, we may want to make both orders available.

The handler is now capable of uploading crash reports from the database.
At present, only one upload attempt is made, and the report will be
moved to “completed” in the database after the attempt, regardless of
whether it succeeded or failed.
The handler also has support to push annotations from its command line
into the process annotations map of each crash report it writes. This is
intended to set basic information about each crash report, such as the
product ID and version. Each potentially crashy process can’t be relied
on to maintain this information on their own.
With this change, Crashpad is now 100% capable of running a handler that
maintains a database and uploads crash reports to a Breakpad-type server
such that Breakpad properly interprets the reports. This is all possible
from the command line.

read any other module information from minidump files. These annotations
are all that are necessary to be able to upload Crashpad-produced

between classic and extension structures.
Previosly, each MinidumpModuleCrashpadInfo structure contained a
minidump_module_list_index field referencing a module in the
MINIDUMP_MODULE_LIST stream by index. This layout was discovered to
cause a problem for the new minidump reader in ModuleSnapshotMinidump.
Instead, the module list index for linkage should be contained in the
MinidumpModuleCrashpadInfoList alongside the LOCATION_DESCRIPTORs
pointing to each MinidumpModuleCrashpadInfo.
The organizational difference is small, but this enables a better design
for ModuleSnapshotMinidump. When initializing a ModuleSnapshotMinidump
with the new layout, it is possible for the caller to have access to the
location descriptor for the MinidumpModuleCrashpadInfo corresponding to
a MINIDUMP_MODULE_LIST. Previously, the caller would not have had this
data without interpreting each MinidumpModuleCrashpadInfo, which
ModuleSnapshotMinidump would have to do anyway.
MinidumpModuleCrashpadInfoListWriter was the only user of
MinidumpLocationDescriptorListWriter, which is obsoleted and removed in
this change. Its functionality is moving directly into
MinidumpModuleCrashpadInfoListWriter, but it is no longer generic enough
to maintain as a distinct class.

Some annotations will exist at a broader scope than per-module, which is
the only place that annotations can currently be stored. The product
name and version are not under the control of any module, but are
established when the first Crashpad client establishes a handler. These
annotations will be stored in a minidump’s MinidumpCrashpadInfo
structure, which applies to the entire minidump.
Within the snapshot interface, this data is carried within the
“process” snapshot because it is the top-level structure in that family.
Note that the data may not correspond directly with a process, however.

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.
