Upgrade Breakpad to latest
This commit will upgrade breakpad to version 1.0.86
(I9957f27cd134f862b9831e4b1d90f8a014eb37b6) from
https://chromium.googlesource.com/breakpad/breakpad
Added a script(BreakpadSwiftCleanup.sh) that remove files from Breakpad's
repository that are not used by Swift.
This commit also re-applies the changes that were introduced in commit
7f0fe603be200c09c74cf9cc295a972f3c3dbdfd, that change the minidump
filename format to include version and date
Test-Information:
https://travis-ci.org/google/breakpad/builds/283789304
https://ci.appveyor.com/project/vapier/breakpad/build/job/1bu73ysmcfpwg9e4
Tested by adding some code that forces a crash to the client on Windows 10
with VS2015. Verified the name and contents of the generated crash dump.
