Change subject: IMPALA-4226, IMPALA-4227: bump max threads, handle dwz compressed symbols

Patch Set 1:


Thanks for the review. Please see my inline comments.
File source/breakpad/breakpad-88e5b2c8806bac3f2c80d2fe80094be5bd371601-patches/0002-Bump-max_threads-and-max_regions.patch:

Line 18: -uint32_t MinidumpThreadList::max_threads_ = 4096;
> Should we try and get this fixed upstream? E.g. by making it a command-line
Good point, I pinged the breakpad dev list and suggested doing this. In that case we would
need to bump our version, so it would require an additional change to the toolchain. Would
you be ok with keeping this here as a workaround until it is fixed upstream?

Line 19: +uint32_t MinidumpThreadList::max_threads_ = 32786;
> Is this enough? I believe sometimes we increase this further.
I haven't seen minidumps with more threads in the wild but I'm happy to bump this to a larger
number. I don't know what else will break if this gets too large, so I tried to stay somewhat
conservative here. Do you have a suggestion?
