19e6087bb2 Don't restrict ImageAnnotationReader to a module's address range
Annotations data structures may be dynamically allocated so could
appear outside a modules's address range. Let ImageAnnotationReader
use a ProcessMemoryRange for the process, rather than the module.

Also add a test for linux.

c82309f0e5 fuchsia: Implement StartHandler() and ExceptionHandlerServer
StartHandler() binds to the default job's exception port, and launches
the handler process (normally this is crashpad_handler), passing it the
task handle and a handle to the exception port as startup parameters.
This follows the protocol used by crashlogger.

Additionally, implement ExceptionHandlerServer in crashpad_handler,
which contains the exception processing loop. It currently dispatches to
an empty CrashReportExceptionHandler where a report will be written
eventually.

b08165c9e5 Extract BuildHandlerArgvStrings to common shared location
I plan to have Fuchsia use a "StartHandlerAtCrash" style similar to
Linux, so pull the argv preservation out into a location where it can be
shared between crashpad_client_linux.cc and crashpad_client_fuchsia.cc
(in upcoming sets).

8d0d999d92 Add a cross-platform database implementation
This CL, based on
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/689745
adds a cross-platform database implementation side-by-side with the
existing macOS and Windows implementations. The generic implementation
is used for Linux, Android and Fuchsia.

The database uses the directory structure from the macOS
implementation, but stores report metadata in companion files for each
report, rather than using filesystem attributes. The database uses
lockfiles (companion files opened with O_EXCL) to protect report access
because they are widely supported across filesystems. Lost lockfiles
are removed after 3 days, along with any reports or metadata they were
protecting.

7faa2ef898 Get CrashpadInfo address via a .note, rather than dynamic symtab
Embeds the address of g_crashpad_info into a .note section (which is
readable by the generic code to read notes in ElfImageReader).
Unfortunately because the note section is in libclient.a, it would
normally be dropped at link time.  To avoid that, GetCrashpadInfo() has
a reference *back* to that section, which in turn forces the linker to
include it, allowing the note reader to find it at runtime.

Previously, it was necessary to have the embedder of "client" figure out
how to cause `g_crashpad_info` to appear in the final module's dynamic
symbol table.  With this new approach, there's no manual configuration
necessary, as it's not necessary for the symbol to be exported.

This is currently only implemented in the Linux module reader (and I
believe the current set of enabled tests aren't exercising it?) but it
will also be done this way for the Fuchsia implementation of
ModuleSnapshot.

457cc6a34f gn: Refactor build files to avoid build/secondary
In doing standalone bringup of Crashpad targeting Fuchsia, it seemed
tidy to keep the same literal paths to the dependencies that Chromium
needed and add stubs/forwarding to build/secondary in the Crashpad tree
as required to make those work.

However, when trying to build Crashpad in the Fuchsia tree itself, that
would require adding forwarding files to the Fuchsia tree to match the
Chromium directory structure, which would be awkward. Instead, have
explicit dependencies in the Crashpad tree that select the locations
for various dependencies.

2bb56fafe3 Rework GN files to start to support building standalone, and also in Chromium
- Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's
  build/BUILD.gn.
- Adds some stub BUILD.gn files in locations where Chromium expects them
  (in //build, //testing, //third_party) containing empty targets/configs.
  These are no-ops in standalone builds, but add functionality when
  building in Chromium.  This is in preference to having a global bool
  that conditionally does Chromium-y things in the Crashpad build files.
  These stub files are all contained in a secondary source root in
  build/chromium_compatibility, referred to by //.gn.
- Adds //base/BUILD.gn which forwards to mini_chromium/base. This is
  only used when building standalone so that both Chromium and Crashpad
  can refer to it as "//base".
- Changes references to other Crashpad targets to be relatively
  specified so that they work when the root of the project is //, and also
  when it's //third_party/crashpad/crashpad as it is in Chromium.
- Moves any error-causing Mac/Win-specific files into explicit if (is_mac)
  or if (is_win) blocks as part of removing the dependency on
  set_sources_assignment_filter().

As yet unresolved:
- CRASHPAD_IN_CHROMIUM needs to be removed when standalone; to be tackled
  in a follow up.
- Not sure what to do with zlib yet, the build file currently assumes
  "in Chromium" too, and similarly having Crashpad //third_party/zlib:zlib
  pointing at itself doesn't work.

d5ead4d70f Upstream lightly modified Chromium BUILD.gn files
Unreferenced, and not working at all in Crashpad-standalone.

Copied from Chromium at 52a9831d81f2099ef9f50fcdaca5853019262c35 to have
a point where a roll back into Chromium should be a no-op (with Chromium's
build/secondary/third_party/crashpad/... removed).

I'm not sure what we want to do about the various gni references into
Chromium (e.g. //build/config/sanitizers/sanitizers.gni, //testing/test.gni,
etc.) but I guess the sooner they live in Crashpad rather than in Chromium
the sooner we can figure out the sort of knobs and dials we need.
