* changes:
  cleanups and fixes for process_madvise compaction
  Avoid unnecessary smaps logic during app compaction
  CachedAppOptimizer: fix fd leak.
  Fix function return type
  Migrate to use process_madvise syscall instead of procfs interface for memory compaction

some fix suggestions that came up on ag/13665789 and some other cleanups
1. Use unique_fd instead of raw int to keep pidfd
2. Return the total compacted bytes on success for compactProcess
3. Fix for error potentially returning a random value
4. Fix truncation that could happen when calling madvise
5. Fail fast after encountering an error instead of silently
advancing to other VMAs when compacting.

ForEachVma can extract data from both maps and smaps files,
however the smaps logic is not used during app compaction.
Replace its usage with ForEachVmaFromMaps which reads only
maps file and skips any smaps logic.
This results in ~22% CPU usage reduction.

errno isn't modified when a syscall returns successfully: this would
leak if errno was already non-zero before entering this function.

Currently the system uses procfs and we are migrating to use a syscall
called process_madvise which makes the code upstreamable and will allow
for making compaction widely available for multiple android devices.

It also opens room for future developments that involve a finer grain
VMA compressions than the current procfs allows.

Test: Ran the system without crashes and verified am_compact was effectively showing compressed memory (free zram reduced) when compressing.

Bug: 162993824
Test: Manual, verified that zram was being increased over time after compactions happened

ApiLint tries to only lint "new" APIs, i.e. those introduced since the
last frozen API. Using android-non-updatable's last frozen txt does not
work well for this, as it is incomplete API surface on its own, so
metalava cannot see all APIs that were present in the previous API
(such as methods inherited from ART), and so makes the wrong decisions
for which APIs are new.
