aabc485b64 fuchsia: Use ZX_TIME_INFINITE instead of UINT64_MAX
In the future, Zircon's time types will change from unsigned to
signed. Use ZX_TIME_INFINITE instead of UINT64_MAX when
zx_nanosleep'ing.

See related Zircon bug ZX-2100.

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.

f55a8d4ff3 fuchsia: Work around lack of packaging in Fuchsia tree build
Packaged test running seems to be a ways off, but with a bit of path
fiddling in test_paths.cc we can actually use the paths where the tests
are copied, so do that instead to get all the tests re-enabled. The
setup in BUILD.gn should be mostly-useful once packaging is working as
all helper/data files will need to specified there anyway.

Also, attempted fix to flaky behaviour in
ProcessReaderFuchsia.ChildThreads exposed because the tests are now
being run. zx_object_wait_many() waits on *any* of the objects, not
*all* of them. Derp!

And finally, for the same test, work around some unintuitive behaviour
in zx_task_suspend(), in particular that the thread will not be
suspended for the purpose of reading registers right away, but instead
only "sometime later", which appears in pratice to be after the next
context switch. Have ScopedTaskSuspend block for a while to try to
ensure the registers become readble, and if they don't, at least fail
noisily at that point.

31703a585f fuchsia: When in Fuchsia tree, disable tests requiring external files
The package deployment/running is in flux at the moment. In order to get
all the other tests on to the main Fuchsia waterfall, disable the ~25
tests that require external files (for launching child processes,
loading modules, or data files) because those operations all fail on
Fuchsia-without-packages right now. Upstream this is PKG-46. Once test
packaging and running has been resolved, this can be reverted.

These tests are still run when building Crashpad standalone on Fuchsia
as the standalone build simply copies all the relevant data files to the
device in /tmp.

bce68d7975 fuchsia: Miscellaneous fixes to get symbol resolution working
- Endian-swaps the 3 integer fields of the build id when returning it
  for use as the module id (see bug 229).
- Removes the "app:" prefix on the main binary, as this prevents the
  crash server from matching the binary name (and it isn't particularly
  useful anyway)
- Map "<vDSO>" to "libzircon.so" as that's what it actually is, so that
  symbols for it can be found.

f5d5a41317 fuchsia: Add implementation of ScopedTaskSuspend

however, threads must be suspended in order to use the register capture
debug API so this is somewhat useful for now in the context of

Also, refactor some child-object retrieval helpers used in a few places.

d9bf38f39c fuchsia: More fixes to get a basic minidump written
With this `generate_dump <somepid>` generates a valid and somewhat
plausible (but still quite incomplete) minidump.

As an example, on a running Fuchsia system, `ps` reported the pid of
"netstack" as 6062, followed by `generate_dump 6062`, copy minidump.6062
to host, and run Breakpad's minidump_dump on the generated dump file,
resulting in:
https://gist.github.com/sgraham/24e4ba1af968219d7c154bb0fba43925

This looks roughly correct in that it has a bunch of threads (without
much data) and a reasonable looking module list.

f5f0aa4a8e fuchsia: Implementation of system snapshot

fields. ARM64 isn't implemented at all and would hit a lot of
