Move sync/notifier to components/invalidation
Moves all code remaining in sync/notifier to components/invalidation.
Updates gyp files, DEPS, and #includes accordingly.
In terms of program behavior, this should be one big no-op. This CL
contains no non-trivial code changes.
In terms of the build system, this is a significant change. Symbols
that were previously exported through sync_notifier and related targets
have moved into the components/invalidation related targets. Some
SYNC_EXPORT macros have been replaced with INVALIDATION_EXPORT, which is
significant since INVALIDATION_EXPORT is currently a no-op but
SYNC_EXPORT has meaning under some build configurations.
Unlike most other files in sync/notifier, invalidation_util.{cc,h} was
moved to sync/internal_api/public/base. This is so it could be
referenced from sync/internal_api/public/base/invalidation.cc. This is
a slight regression, but it should be fixed in the next CL when we move
all invalidations-related code out of sync/internal_api.
