Update breakpad to support Android NDK r10c
Prior to NDK r10c, Breakpad was privately backporting these system headers. This change is now unforking and removing those headers and using the ones from the NDK. Rationale: - They are finally available in the NDK, so there is no need to keep maintaining a fork (which was necessary up until recently to support arm64). - These forked headers, as they are today, are not compatible with the latest NDK (i.e. this change is required to roll NDK r10c). The forked ucontext.h, being removed by this CL, depends on some transitional features which are not compatible with the NDK release being targeted here. After this change, the NDK r10c is now required to build Breakpad on Android. Note that NDK releases are backwards compatible and contain all the previous API levels, so this change is NOT effectively enforcing to build against any particular Android SDK. Submitting this on behalf of fdegans@chromium.org BUG=chromium:358831 R=mark@chromium.org, primiano@chromium.org, rmcilroy@chromium.org git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1396 4c0a9323-5329-0410-9bdc-e9ce6186880e
