dee16d9b30 dwarf_cu_to_module_unittest: remove expectation
This expectation started failing at
8b68c72a3f. Remove it.

This is the only expectation that exists in this test, but the test
may be useful for internal asserts performed in the code under test.

0c816d2d12 module_unittest: fix use-after-free
`Construct.FunctionsWithSameAddress` started failing at ff5892c5. It
looks like the cause of this is in the calls to
`generate_duplicate_function`:

```
generate_duplicate_function("_without_form");
generate_duplicate_function("_and_void");
```

`generate_duplicate_function` directly calls `new
Module::Function(...);`, which stores the `StringView` it's given.
`generate_duplicate_function` currently takes a `const
string &`; in the above statements, these strings get `free()`d at the
`;`.

Making the parameter a `StringView` means the `Module::Function` will
store pointers to the string literal, which lives for the whole program.

All calls to `generate_duplicate_function` are given literals.

Some systems have constrained rlimits for core files (the CrOS chroot is

0808030bee Support PE modules in core files when running core2md
Core files generated from `wine` contain both ELF and PE modules. Module
format can be guessed by checking the file contents. If the module
corresponds to PE-file conditions (has specific fields set up as
described in https://code.google.com/archive/p/corkami/wikis/PE.wiki)
we'll create a MDCVInfoPDB70 record in the minidump for it, but if
the file cannot be opened, is too short or is not a PE file, we'll
fall back to ELF procedure.

Added /src/client/linux/minidump_writer/pe_file.{cc,h} to
src_client_linux_libbreakpad_client_a_SOURCES and
src_client_linux_linux_client_unittest_shlib_SOURCES.
Makefile.in and aclocal.m4 were generated by running 'aclocal && automake'.

Test: build core2md and use it to convert a core file into dmp, validate
that the generated dmp file can be opened. Ran './configure & make'.

c85eb4a59b avoid dump_syms crashing if selected arch is not found
https://crrev.com/c/3327644 introduced the ability for dump_syms to
operate on in memory data, which has the consequence of not going
through the same input validation as the dump_syms cli tool. In certain
cases, it is possible that architecture info can't be reliably
determined, e.g. new architectures that breakpad is unware of. In that
case, dump_syms should avoid crashing when calling ReadSymbolData and
return false instead.

634a7b3fad mac: add go.mod for upload_system_symbols
This was created by running “go mod init upload_system_symbols”. This is
necessary for “go build” to work in recent versions of golang.
Previously, errors such as this were produced:

go: cannot find main module, but found .git/config in …/breakpad/src
	to create a module there, run:
	cd ../../../.. && go mod init

605c51ed96 Fix for non-constant SIGSTKSZ
On glibc > 2.33, `SIGSTKSZ` might not be constant (in which case
it expands to a call to `sysconf` which returns a `long int`); see
https://sourceware.org/pipermail/libc-alpha/2020-October/118513.html

Pass unsigned explicitly to std::max, to avoid relying on template
argument deduction. This works both with the old-style constant
`SIGSTKSZ` and the new configurable one.

Initially based on https://chromium-review.googlesource.com/c/2776379

3846f6d297 Add <call_site_file_id> to INLINE and remove <file_id> from INLINE_ORIGIN
This is the dump_syms side change on
https://chromium-review.googlesource.com/c/breakpad/breakpad/+/3232838/.
This fixes incorrect source file names when a inlined function's source
file name is different from its parent's.

64b25d6653 Fixing issues in the Breakpad symbol file serialization code.
- FastSourceLineResolver::Module::LoadMapFromMemory now rejects an older version of the serialization format.
- Cleaned up several unneeded usages of scoped_ptr::get.
- Fixed the serialization of bool. The serialization code was using 255 for 'true' while the deserialization code was expecting to see 1.
- Serialization for PublicSymbol.is_multiple was missing. Deserialization was expecting it
- Added some logging to processor/source_line_resolver_base.cc

- Ignore DW_TAG_inlined_subroutine with empty range.
- Don't stop parsing after parsing malformed INLINE/INLINE_ORIGIN
records, because reports can still be generated without them but won't
have inlined frames.

This adds a new mode in ContainedRangeMap which allows existance of
equal ranges. Among those equal ranges, the most recently added range is
the innermost range.

This also adds a function to ContainedRangeMap and
StaticContainedRangeMap to allow users get a vector of entries that
contains given address from innermost to outermost ranges.
