This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.

Also remove MemorySnapshotWin since the code is identical to

Add a method to the ProcessSnapshot to expose a ProcessMemory object to
allow reading memory directly from the underlying process.

Because DumpAndCrashTargetProcess() suspends the process, the thread
suspend count is one too high for all threads other than the injection
one in the thread snapshots. Compensate for this when we detect this
type of exception.

Add a user-configurable cap on the amount of memory that is gathered by
dereferencing thread stacks. (SyzyAsan stores a tremendously large
number of pointers on the stack, so the dumps were ending up in the ~25M
range.)
Also reduce the range around pointers somewhat.

This was done in Chromium’s local copy of Crashpad in 562827afb599. This
change is similar to that one, except more care was taken to avoid
including headers from a .cc or _test.cc when already included by the
associated .h. Rather than using <stddef.h> for size_t, Crashpad has
always used <sys/types.h>, so that’s used here as well.
This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc,
which removes base/basictypes.h.
e128dcf10122 Remove base/move.h; use std::move() instead of Pass()

On Win 7 in a debug configuration, walking all locks was gathering
hundreds of thousands of locks, causing test timeouts to be exceeded in
debug. On user machines, UnhandledExceptionHandler() could have timed
out too. For now, only grab the loader lock as it's the most interesting
one. Unfortunately, this means that !locks won't work for now.
In the future, we may want to figure out a signalling mechanism so that
the client can note other interesting locks to be grabbed, and just
avoid walking the list entirely.

Capture the memory for the loader lock (can be inspected by !cs), as

This makes the basics of !peb work in windbg, however, pointed-to things

the PEB also needs to be walked and captured.

The next big piece of functionality in snapshot. There's a bit more
grubbing around in the NT internals than would be nice, and it has
made me start to question the value avoiding MinidumpWriteDump. But
this seems to extract most of the data we need (I haven't pulled
the cpu context yet, but I hope that won't be too hard.)

The main goal was to get the beginnings of module iteration and retrieval
of CrashpadInfo in snapshot. The main change for that is to move
crashpad_info_client_options[_test] down out of mac/.
This also requires adding some of the supporting code of snapshot in
ProcessReaderWin, ProcessSnapshotWin, and ModuleSnapshotWin. These are
partially copied from Mac or stubbed out with lots of TODO annotations.
This is a bit unfortunate, but seemed like the most productive way to
make progress incrementally. That is, it's mostly placeholder at the
moment, but hopefully has the right shape for things to come.
