9e79ea1da7 Split *_test.gyp from *.gyp.
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.

26804a0be1 Add ASSERT_DEATH_CHECK() to do ASSERT_DEATH() of CHECK() failures.
Likewise for EXPECT_DEATH_CHECK() and EXPECT_DEATH().

In the in-Chromium build configured for official builds in Release mode,
CHECK() throws away its condition string and stream parameters without
ever printing them, although it still evaluates the condition and
triggers death appropriately. {ASSERT,EXPECT}_DEATH(statement, regex)
will not work correctly for any regex that attempts to match what
CHECK() prints. In these build configurations,
{ASSERT,EXPECT}_DEATH_CHECK() use a match-all regex (""). In other build
configurations, they transparently wrap {ASSERT,EXPECT}_DEATH().

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.

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.

4539fd1553 minidump: Reorganize MinidumpModuleCrashpadInfo to improve linking
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.

a980409288 Add MinidumpRVAListWriter and test.
This will be used as the foundation for writing a list of
MinidumpUTF8String objects. MinidumpUTF8String (and UTF-16
MINIDUMP_STRING) objects are never referenced by
MINIDUMP_LOCATION_DESCRIPTOR because they carry their own lengths.
Instead, they are always referenced by RVA.

The list of MinidumpUTF8String objects will be used for the module
annotations vector.
