a8ff626764 Add a bunch of missing string.h includes.
There are a few files in the tree which use various functions defined
in string.h (memcpy, strlen, strnlen, memmove, etc), but never include
the necessary header file. After I've recently updated one of my systems
to a newer glibc version (2.30) this code failed to build. Adding the
missing includes fixes the problem.

The undeclared functions for each file are:
* simple_address_range_bag.h - memcpy
* http_multipart_builder.cc - strlen
* minidump_context_converter.cc - memcpy
* ptrace_client.cc - strlen
* http_transport_socket.cc - strncpy, strlen, memcpy
* process_memory.cc - memchr
* log_output_stream.cc - strlen

c96226c6ba linux: move handler protocol types into a class
This patch adds the class ExceptionHandlerProtocol to contain all the
relevant types, but should not make any functional changes.

cc166d71f4 Use base::size where appropriate, and ArraySize elsewhere
This is a follow-up to c8a016b99d97, following the post-landing
discussion at
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/1393921/5#message-2058541d8c4505d20a990ab7734cd758e437a5f7

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.

Includes:
Update mini_chromium to 737433ebade4d446643c6c07daae02a67e8deccao

f701716d9546 Add Windows ARM64 build target to mini_chromium
87a95a3d6ac2 Remove the arraysize macro

10fd672bde linux: Enable brokered memory reading
This change:
1. Updates the broker's memory reading protocol to enable short reads.
2. Updates Ptracer to allow short reads.
3. Updates the broker to allow reading from a memory file.
4. Updates the broker's default file root to be "/proc/[pid]/".
5. Adds PtraceConnection::Memory() to produce a suitable memory reader
for a connection type.

d108fd04a5 linux: Add PtraceConnection::ReadFileContents
Some files, such as /proc/[pid]/maps, may not be accessible to the
handler. This enables the handler access to the contents of those files
via the broker.

This change reads maps and auxv using ReadFileContents.

The broker runs in a process with `ptrace` capabilities for the target
