14138936b5 test: Compare ProcessInfo::Arguments() to main()’s argc/argv on POSIX
Previously on macOS, the test used an OS-specific library function to
recover the original argc and argv. On Linux/Android, it essentially
reimplemented the very code it was testing, which didn’t make for a very
good test. The new approach is to save argc and argv in main() and base
the comparison on that.

Bug: crashpad:30
Test: crashpad_util_test ProcessInfo.*, crashpad_test_test MainArguments.*

9be4745be0 linux: Lazily initialize ProcessInfo’s Is64Bit() and StartTime()
Lazy initialization is particularly beneficial for Is64Bit(), which uses
a different (ptrace()-based) approach than the rest of the class (which
is /proc-based). It is possible for the /proc-based Initialize() to
succeed while ptrace() would fail, as it typically would in the
ProcessInfo.Pid1 test. Because this test does not call Is64Bit(),
permission to ptrace() shouldn’t be necessary, and in fact ptrace()
shouldn’t even be called.

This enables the ProcessInfo.Pid1 test on Android (due to ptrace(), it
was actually failing on any Linux, not just Android). It also enables
the ProcessInfo.Forked test on non-Linux, as the prctl(PR_SET_DUMPABLE)
Linux-ism can be removed from it.

b978b03fa1 Port most of crashpad_util_test to Linux/Android
- In the ProcessInfo test, port the global argc/argv getter to Linux by
   reading /proc/self/cmdline.
 - Use <inttypes.h> format macros for 64-bit types.
 - Only #include <sys/sysctl.h> on macOS.
 - #include <signal.h> instead of <sys/signal.h>.

In order to test on Linux/Android, the following changes to the
crashpad_util_test target must be made until more porting is complete:

 - Remove the dependency on crashpad_client because that library has not
   been ported yet.
 - Remove process_info_test.cc because it depends on crashpad_client and
   there is no implementation of ProcessInfo for Linux yet.
 - Remove http_transport_test.cc because there is no HTTPTransport
   implementation for Linux or Android yet.
 - Remove checked_address_range_test.cc because checked_address_range.cc
   does not yet expose a cross-bit usable type for addresses and sizes
   on Linux.

4ff6c2d71f Remove #include "base/basictypes.h" as appropriate
These files were only using basictypes.h for implicit_cast, which moved
to util/misc/implicit_cast.h in 0b022d72a2a4.

0b022d72a2 Include implicit_cast.h at all users of it.
The implicit_cast in base will be no more, make sure we have a reference
to the crashpad version at all callsites.

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.

6812cec67e Move some parts of ProcessReader (in snapshot) to ProcessInfo (in util).
Also, move ProcessArgumentsForPID() into ProcessInfo.

This change prepares for a TaskForPID() implementation that’s capable of
operating correctly in a setuid root executable. TaskForPID() belongs in
util/mach, but for its permission checks, it must access some process
properties that were previously fetched by ProcessReader in snapshot.
util can’t depend on snapshot. The generic util-safe process information
bits (Is64Bit(), ProcessID(), ParentProcessID(), and StartTime()) are
moved from ProcessReader to ProcessInfo (in util), where the current
ProcessReader can use it (as it’s OK for snapshot to depend on util),
and the future TaskForPID() in util can also use it. ProcessInfo also
contains other methods that TaskForPID() will use, providing access to
the credentials that the target process holds. ProcessArgumentsForPID()
is related, and is also now a part of ProcessInfo.
