Tune GNU malloc (#2299) ## Issue Addressed NA ## Proposed Changes Modify the configuration of [GNU malloc](https://www.gnu.org/software/libc/manual/html_node/The-GNU-Allocator.html) to reduce memory footprint. - Set `M_ARENA_MAX` to 4. - This reduces memory fragmentation at the cost of contention between threads. - Set `M_MMAP_THRESHOLD` to 2mb - This means that any allocation >= 2mb is allocated via an anonymous mmap, instead of on the heap/arena. This reduces memory fragmentation since we don't need to keep growing the heap to find big contiguous slabs of free memory. - ~~Run `malloc_trim` every 60 seconds.~~ - ~~This shaves unused memory from the top of the heap, preventing the heap from constantly growing.~~ - Removed, see: https://github.com/sigp/lighthouse/pull/2299#issuecomment-825322646 *Note: this only provides memory savings on the Linux (glibc) platform.* ## Additional Info I'm going to close #2288 in favor of this for the following reasons: - I've managed to get the memory footprint *smaller* here than with jemalloc. - This PR seems to be less of a dramatic change than bringing in the jemalloc dep. - The changes in this PR are strictly runtime changes, so we can create CLI flags which disable them completely. Since this change is wide-reaching and complex, it's nice to have an easy "escape hatch" if there are undesired consequences. ## TODO - [x] Allow configuration via CLI flags - [x] Test on Mac - [x] Test on RasPi. - [x] Determine if GNU malloc is present? - I'm not quite sure how to detect for glibc.. This issue suggests we can't really: https://github.com/rust-lang/rust/issues/33244 - [x] Make a clear argument regarding the affect of this on CPU utilization. - [x] Test with higher `M_ARENA_MAX` values. - [x] Test with longer trim intervals - [x] Add some stats about memory savings - [x] Remove `malloc_trim` calls & code

Move dependencies to workspace (#4650) ## Issue Addressed Synchronize dependencies and edition on the workspace `Cargo.toml` ## Proposed Changes with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies. By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times. ## Additional Info this PR also removes the no longer required direct dependency of the `serde_derive` crate. should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged. closes https://github.com/sigp/lighthouse/issues/4651 Co-authored-by: Michael Sproul <michael@sigmaprime.io> Co-authored-by: Michael Sproul <micsproul@gmail.com>

Enable `mallinfo2` behind feature flag (#2864) ## Proposed Changes Add `mallinfo2` behind a feature flag so that we can get accurate memory metrics during debugging. It can be enabled when building Lighthouse like so (so long as the platform supports it): ``` cargo install --path lighthouse --features "malloc_utils/mallinfo2" ```
