Postgres can always write some more WAL, so previous checks that WAL doesn't
change after something had been crafted were wrong; remove them. Add comments
here and there.
should fix https://github.com/neondatabase/neon/issues/4691
## Problem
Neon doesn't compile on nightly and had numerous clippy complaints.
## Summary of changes
1. Fixed troublesome dependency
2. Fixed or ignored the lints where appropriate
Fixes#4689 by replacing all of `std::Path` , `std::PathBuf` with
`camino::Utf8Path`, `camino::Utf8PathBuf` in
- pageserver
- safekeeper
- control_plane
- libs/remote_storage

This adds PostgreSQL 16 as a vendored postgresql version, and adapts the
code to support this version.
The important changes to PostgreSQL 16 compared to the PostgreSQL 15
changeset include the addition of a neon_rmgr instead of altering Postgres's
original WAL format.

## Problem
close https://github.com/neondatabase/neon/issues/4266
## Summary of changes
With this PR, rust-analyzer should be able to give lints and auto
complete in `mod tests`, and this makes writing tests easier.
Previously, rust-analyzer cannot do auto completion.

wal_craft had accumulated some trouble by using `use anyhow::*;`. Fixes
that, removes redundant conversions (never need to convert a Path to
OsStr), especially at the `Process` args.
Originally in #4100 but we merged a later PR instead for the fixes. I
dropped the `postmaster.pid` polling in favor of just having a longer
connect timeout.
1.66 release speeds up compile times for over 10% according to tests.
Also its Clippy finds plenty of old nits in our code:
* useless conversion, `foo as u8` where `foo: u8` and similar, removed
`as u8` and similar
* useless references and dereferenced (that were automatically adjusted
by the compiler), removed various `&` and `*`
* bool -> u8 conversion via `if/else`, changed to `u8::from`
* Map `.iter()` calls where only values were used, changed to
`.values()` instead
Standing out lints:
* `Eq` is missing in our protoc generated structs. Silenced, does not
seem crucial for us.
* `fn default` looks like the one from `Default` trait, so I've
implemented that instead and replaced the `dummy_*` method in tests with
`::default()` invocation
* Clippy detected that
```
if retry_attempt < u32::MAX {
retry_attempt += 1;
}
```
is a saturating add and proposed to replace it.
Another preparatory commit for pg15 support:
* generate bindings for both pg14 and pg15;
* update Makefile and CI scripts: now neon build depends on both PostgreSQL versions;
* some code refactoring to decrease version-specific dependencies.
Re-export only things that are used by other modules.
In the future, I'm imagining that we run bindgen twice, for Postgres
v14 and v15. The two sets of bindings would go into separate
'bindings_v14' and 'bindings_v15' modules.
Rearrange postgres_ffi modules.
Move function, to avoid Postgres version dependency in timelines.rs
Move function to generate a logical-message WAL record to postgres_ffi.
* Deduce `last_segment` automatically
* Get rid of local `wal_dir`/`wal_seg_size` variables
* Prepare to test parsing of WAL from multiple specific points, not just the start;
extract `check_end_of_wal` function to check both partial and non-partial WAL segments.
