240e28df2b Make run_with_crashpad buildable on Fuchsia too
Exception handling in Zircon is very similar to Mach
(https://fuchsia.googlesource.com/zircon/+/HEAD/docs/exceptions.md), so
run_with_crashpad will be useful for testing.

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.

60ae9eeadb Implementation of HTTPTransport via raw socket
Partial implementation: Currently only handles http (i.e. no TLS), only
POST, and only certain response types (only when Content-Length is
specified, and not chunked). Used for Linux and Fuchsia lacking anything
better (that's shippable). Removes libcurl HTTPTransport, since it isn't
available in the Chromium sysroot anyway.

This is an intermediate step until BoringSSL is available in the Fuchsia
SDK. Once that's available, it should be "relatively straightfoward" to
make http_transport_socket.cc secure its socket using BoringSSL or
OpenSSL depending on the platform.

c80bf96001 Don't record reports as complete if there is no upload thread
This allows clients to use the database to handle uploads themselves,
e.g. on Android, where Crashpad does not yet provide an uploader.

The handler does not launch an upload thread when no url is supplied.
Previously, the handler would move these reports to

With this change, these reports would remain pending until pruned,
with no metrics recorded for them in regard to their upload.

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.

3a20d34ac3 Fix build with glibc 2.27
Glibc now defines PTRACE_GET_THREAD_AREA as an enum value.  Trying to define our
own will result in an error:

../../third_party/crashpad/crashpad/compat/linux/sys/ptrace.h:25:35: error: redefinition of 'PTRACE_GET_THREAD_AREA' as different kind of symbol
static constexpr __ptrace_request PTRACE_GET_THREAD_AREA =
                                  ^
../../build/linux/debian_sid_amd64-sysroot/usr/include/x86_64-linux-gnu/sys/ptrace.h:110:3: note: previous definition is here
  PTRACE_GET_THREAD_AREA = 25,

However, glibc also defines a new macro for the corresponding value, so it's
possible to detect this case:

----- ptrace.h -----
  /* Get a TLS entry in the GDT.  */
  PTRACE_GET_THREAD_AREA = 25,
#define PT_GET_THREAD_AREA PTRACE_GET_THREAD_AREA
----- ptrace.h -----

This CL prevents defining our own PTRACE_GET_THREAD_AREA when PT_GET_THREAD_AREA
is defined.

10fd672bde linux: Enable brokered memory reading
This change:
1. Updates the broker's memory reading protocol to enable short reads.
2. Updates Ptracer to allow short reads.
3. Updates the broker to allow reading from a memory file.
4. Updates the broker's default file root to be "/proc/[pid]/".
5. Adds PtraceConnection::Memory() to produce a suitable memory reader
for a connection type.

which moved responsibility for sending a ForkBroker request to
PtraceDecider. MockPtraceDecider wasn't updated to send this request,
so no broker was forked.

08ce02c352 Fix crashpad build on non Android ARMEL with a recent GLIBC.
user_vfp is not declared anymore in sys/user.h, but in specific
internal kernel asm user.h in GLIBC. So building crashpad on ARMEL
with such a GLIBC will fail to build.

Also, sys/ptrace.h will not include the declarations for
PTRACE_GET_THREAD_AREA and PTRACE_GETVFPREG in arm (they are in
asm/ptrace.h and not included from sys/ptrace.h). So provide
compatibility declarations accordingly for arm architecture.
