offsets in the MemoryMap are expressed as two's complement while
Crashpad's and mini_chromium's string conversion functions expect
negative numbers to be expressed with a '-' character.
Convert the string as unsigned and then re-interpret to signed when
necessary.

base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:
minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)
The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

mig_fix.py also has the option to write its fixed output to new files, rather than overwriting the existing output. This should increase compatibility with certain build configurations.

As Mark noted in [1] ProcessMemory should accept VMSize instead of
size_t, the two types can differ on platforms where a cross-bitness
handler could cause a 32-bit handler to inspect a 64-bit process. By
centralizing the checks in ProcessMemory, we can leave the individual
platform-specific implementations (in ProcessMemory*::ReadUpTo) to
accept size_ts.

Currently TaskMemory re-implements a number of Read* routines that are
implemented in a platform-independent way in ProcessMemory with access
to a single platform-specific ReadUpTo method. Implement the ReadUpTo
method for TaskMemory and subclass it from ProcessMemory to inherit the
remaining methods.
The ProcessMemoryTests didn't work on macOS because MultiprocessExec
can not access the child process' task port without root privileges or
the task_for_pid entitlement. Create an adaptor class for those tests to
use MachMultiprocess so that the child process sends its task port to
the parent.

Currently, TaskMemory::ReadCStringInternal() treats the
ReadCStringSizeLimited(size=0) case by returning an empty string;
however, that is inconsistent with the documentation for that function
and the equivalent implementation in ProcessMemory. The comment for the
size parameter is: "The maximum number of bytes to read. The string is
required to be `NUL`-terminated within this many bytes." My
interpretation is that the ProcessMemory behavior is correct in failing
on size=0 as a NUL can never be read.
ReadCStringSizeLimited() is only used with a possibly null size in
MachOImageReader::ReadDylinkerCommand(). In that case we read the
dylinker_command string, which appears to also be verified to be a
non-zero length null terminated string in load_dylinker() in
bsd/kern/mach_loader.c so we shouldn't hit this case in the wild.

Add MemoryMap::Iterator to support different strategies for locating
the start of module mappings on Android and Linux.
Beginning with API 21, Bionic provides android_dlopen_ext() which
allows passing a file descriptor with an existing relro segment to the
loader. This means that the mapping containing the dynamic segment
could have a name, device, and inode which are different than the
other mappings for the module.
The revised strategy for Android at API 21+ is to search all mappings
in reverse order from they dynamic array mapping until a module is
parsed with the expected dynamic array address.
Linux and Android 20- continue to select mappings using the device,
inode, and file offsets of the mappings.

pthread_threadid_np() reports an incorrect thread ID after fork() on
macOS 10.14 (“Mojave”). See https://openradar.appspot.com/43843552. As a
workaround, use thread_info(…, THREAD_IDENTIFIER_INFO, …).
This uses MachThreadSelf(), which in turn uses pthread_mach_thread_np(),
which does not suffer from the same bug. As an alternative,
base::mac::ScopedMachSendRight(mach_thread_self()) could be used.

The desc value in the note is now the offset of CRASHPAD_INFO_SYMBOL
from desc.
Making this note writable can trigger a linker error resulting in
the binary embedding .note.crashpad.info to be rejected by the
kernel during program loading.
The error was observed with:
GNU ld (GNU Binutils for Debian) 2.30
clang version 4.0.1-10 (tags/RELEASE_401/final)
Debian 4.17.17-1rodete2
When the note is made writable, crashpad_snapshot_test contains two
PT_LOAD segments which map to the same page.
LOAD 0x0000000000000000 0x0000000000000000 0x0000000000000000

Executing this binary with the execv system call triggers a segfault
during program loading (an error can't be returned because the original

I suspect (I haven't set up a debuggable kernel) the failure occurs
while attempting to map the second load segment because its virtual
address, 0x258, is in the same page as the first load segment.
https://elixir.bootlin.com/linux/v4.17.17/source/fs/binfmt_elf.c#L380
The linker normally produces consecutive load segments where the second

We were still generating gyp build files on the bots, and then using the
GN build. There's some not-working logic in gyp to find the hermetic
Xcode SDK that the new bots are using, so just avoid generating the gyp
build now, since we're not using it anyway.
(My understanding is that the Android build uses
build/gyp_crashpad_android.py instead not build/gyp_crashpad.py. But
there's no Android bots in any case, so it shouldn't be a problem for
that.)

64 bytes for linux system libraries (on my machine), but so far they're
