This makes it possible for the compiler to validate that a match block
matched all PostgreSQL versions we support.
## Problem
We did not have a complete picture about which places we had to test
against PG versions, and what format these versions were: The full PG
version ID format (Major/minor/bugfix `MMmmbb`) as transfered in
protocol messages, or only the Major release version (`MM`). This meant
type confusion was rampant.
With this change, it becomes easier to develop new version-dependent
features, by making type and niche confusion impossible.
## Summary of changes
Every use of `pg_version` is now typed as either `PgVersionId` (u32,
valued in decimal `MMmmbb`) or PgMajorVersion (an enum, with a value for
every major version we support, serialized and stored like a u32 with
the value of that major version)

## Problem
https://github.com/neondatabase/neon/issues/9965
## Summary of changes
Add safekeeper membership configuration struct itself and storing it in
the control file. In passing also add creation timestamp to the control
file (there were cases where I wanted it in the past).
Remove obsolete unused PersistedPeerInfo struct from control file (still
keep it control_file_upgrade.rs to have it in old upgrade code).
Remove the binary representation of cfile in the roundtrip test.
Updating it is annoying, and we still test the actual roundtrip.
Also add configuration to timeline creation http request, currently used
only in one python test. In passing, slightly change LSNs meaning in the
request: normally start_lsn is passed (the same as ancestor_start_lsn in
similar pageserver call), but we allow specifying higher commit_lsn for
manual intervention if needed. Also when given LSN initialize
term_history with it.
## Problem
We want to extract safekeeper http client to separate crate for use in
storage controller and neon_local. However, many types used in the API
are internal to safekeeper.
## Summary of changes
Move them to safekeeper_api crate. No functional changes.
ref https://github.com/neondatabase/neon/issues/9011
Creates new `pageserver_api` and `safekeeper_api` crates to serve as the
shared dependencies. Should reduce both recompile times and cold compile
times.
Decreases the size of the optimized `neon_local` binary: 380M -> 179M.
No significant changes for anything else (mostly as expected).
