339b125241 [minidump] Fix unaligned pointer in thread name list
https://crrev.com/c/3671775/ introduced a warning (and thus, a
compilation failure) on 32-bit ARM when taking the address of the RVA64
field MINIDUMP_THREAD_NAME::RvaOfThreadName:

minidump/minidump_thread_name_list_writer.cc:57:23: error: taking address of packed member 'RvaOfThreadName' of class or structure 'MINIDUMP_THREAD_NAME' may result in an unaligned pointer value [-Werror,-Waddress-of-packed-member]
  name_->RegisterRVA(&thread_name_.RvaOfThreadName);
                      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Indeed, MINIDUMP_THREAD_NAME's RvaOfThreadName field is not aligned,
so the technique used in MinidumpWritable::Register*() of passing in a
rawptr to an arbitrary struct field which is later dereferenced cannot
be used for this field.

This CL replaces the use of MinidumpWritable::Register*() with
overriding MinidumpThreadNameWriter::WillWriteAtOffsetImpl() to
directly calculate and assign thread_name_.RvaOfThreadName.

a903f7541f [minidump] Add support for RVA64 / MINIDUMP_LOCATION_DESCRIPTOR64
Newer minidump stream types, like MINIDUMP_THREAD_NAME_LIST, use
64-bit RVAs (which have 64-bit location descriptors) instead of 32-bit
RVAs and location descriptors.

This adds support to MinidumpWritable for the new 64-bit RVA64 and
MINIDUMP_LOCATION_DESCRIPTOR64 types.

1aa478d161 Remove DISALLOW_* macros in crashpad
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.

e9f40ae176 Remove double double words
I ran the thing below (piped to “grep -v namespace”), fixed things up,
and rewrapped comments in the affected file.

import re
import sys

LAST_WORD_RE = re.compile('^.*[\s]+([\w]+)$')
FIRST_WORD_RE = re.compile('^[^\w]+([\w]+).*$')

for path in sys.argv[1:]:
  with open(path) as file:
    line_number = 0
    last_word = None
    for line in file:
      line_number += 1
      first_word = FIRST_WORD_RE.match(line)
      if first_word and first_word.group(1) == last_word:
        print('%s:%u: %s' % (path, line_number - 1, last_word))
      last_word = LAST_WORD_RE.match(line)
      if last_word:
        last_word = last_word.group(1)

b653f86153 Fix Windows build after 8f0636288a0e
Clang, GCC, and MSVS 2017 were fine with a “constexpr” definition
corresponding to a class-scope “static const” declaration, but MSVS 2015
is not.

6d2d31d2d1 Use base/macros.h instead of base/basictypes.h
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()

07fcf63c21 win: fixes for Windows x64
Mostly size_t <-> unsigned int warnings, but I also had a mistake in
PROCESS_BASIC_INFORMATION, the pids are 32-on-32 and 64-on-64.

The Windows build is still x86 until https://codereview.chromium.org/981333002/.
I don't think I'll bother maintaining the x86 build for now, though we will probably
need it for x86 OSs in the future. It should be straightforward to revive it once we
need it, and have bots to support it.

429a3368d4 win: Work towards getting 'minidump' to compile
- dbghelp.h requires windows.h to be included before it (ick!).
  Add a stub one for non_win to make this work.
- convert __attribute__ -> macro that can work work with MSVC;
- a handful of narrowing casts.

0a4ea0b52d minidump: Change the ownership model.
All minidump objects now own their all of their children, rather than
having them maintain weak pointers and requiring callers to maintain
ownership.

The only weak object in the entire tree now is the “extra memory” added
to a MinidumpMemoryListWriter by its AddExtraMemory() method. Extra
memory aliases objects owned elsewhere in the tree, typically by a
MinidumpThreadWriter as stack memory. Non-“extra” memory added to a
MinidumpMemoryListWriter by its AddMemory() method is strongly owned.

Many objects are now deleted through base pointers, and in those cases,
the base classes now have public virtual destructors. The ultimate base,
MinidumpWritable, is still protected to guard against direct
instantiation and deletion, and thus its destructor does not need to be
virtual.

This updates mini_chromium to eeb3b6a4f020 specifically for that
revision, which includes necessary updates to scoped_ptr. It also picks
up:
