As noted in the comment, the craft_internal() function fails if the
inserted WAL happens to land at page boundary. I bumped into that with
PR #7377; it changed the arguments of a few SQL functions in
neon_test_utils extension, which changed the WAL positions slightly, and
caused a test failure.
## Problem
See #5468.
## Summary of changes
Add a new `get_timestamp_of_lsn` endpoint, returning the timestamp
associated with the given lsn.
Fixes#5468.

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.

## 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.

Notes:
- This still needs UI support from the Console
- I've not tuned any GUCs for PostgreSQL to make this work better
- Safekeeper has gotten a tweak in which WAL is sent and how: It now
sends zero-ed WAL data from the start of the timeline's first segment up to
the first byte of the timeline to be compatible with normal PostgreSQL
WAL streaming.
- This includes the commits of #3714
Fixes one part of https://github.com/neondatabase/neon/issues/769

- Split postgres_ffi into two version specific files.
- Preserve pg_version in timeline metadata.
- Use pg_version in safekeeper code. Check for postgres major version mismatch.
- Clean up the code to use DEFAULT_PG_VERSION constant everywhere, instead of hardcoding.
- Parameterize python tests: use DEFAULT_PG_VERSION env and pg_version fixture.
To run tests using a specific PostgreSQL version, pass the DEFAULT_PG_VERSION environment variable:
'DEFAULT_PG_VERSION='15' ./scripts/pytest test_runner/regress'
Currently don't all tests pass, because rust code relies on the default version of PostgreSQL in a few places.
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.
* Do not set LSN for new FPI page
refer #1656
* Add page_is_new, page_get_lsn, page_set_lsn functions
* Fix page_is_new implementation
* Add comment from XLogReadBufferForRedoExtended
