Summary: This patch includes several changes to reduce the overall footprint of the allocator: - for realloc'd chunks: only keep the same chunk when lowering the size if the delta is within a page worth of bytes; - when draining a cache: drain the beginning, not the end; we add pointers at the end, so that meant we were draining the most recently added pointers; - change the release code to account for an freed up last page: when scanning the pages, we were looking for pages fully covered by blocks; in the event of the last page, if it's only partially covered, we wouldn't mark it as releasable - even what follows the last chunk is all 0s. So now mark the rest of the page as releasable, and adapt the test; - add a missing `setReleaseToOsIntervalMs` to the cacheless secondary; - adjust the Android classes based on more captures thanks to pcc@'s tool.
