zx_task_suspend() now supports suspending processes. This is somewhat
more reliable than suspending the constituent threads because after the
call returns and the token is being held, any subsequently started
threads will start in the the suspended state.
However, because the suspend is asynchronous the threads of the process
still need to be iterated to wait for them to assert ZX_THREAD_SUSPENDED
(and that can and does still fail to happen for a number of reasons). So
while improved, this class is still only best-effort.
Additionally, as the version of ScopedTaskSuspend that took a thread
wasn't being used, remove that.

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.
