Support opening local store with database on read-only filesystem (#8356)
Previously it was not possible to open a local store when its database is on a read-only filesystem. Obviously a store on a read-only filesystem cannot be modified, but it would still be useful to be able to query it.

This change adds a new read-only setting to LocalStore. When set to true, Nix will skip operations that fail when the database is on a read-only filesystem (acquiring big-lock, schema migration, etc), and the store database will be opened in immutable mode.

a6a75ecad8 GC server: Clear O_NONBLOCK on the right file descriptor
The bug fix in 6d30f9e6fe erroneously
cleared O_NONBLOCK on the server rather than client FD (leaving both
in an incorrect state).

Fixes #8551.

33d3889831 redirect old platform uninstall instruction links
Uninstall instructions were moved to their own page in #8267. The
overall section link was redirected in #8286, but platform-specific
links (which I give out frequently when I triage installer trouble)
weren't included.

9f69b7dee9 Create worker_proto::{Read,Write}Conn
Pass this around instead of `Source &` and `Sink &` directly. This will
give us something to put the protocol version on once the time comes.

To do this ergonomically, we need to expose `RemoteStore::Connection`,
so do that too. Give it some more API docs while we are at it.

4e8b495ad7 Likewise namespace and enum struct-ify ServeCommand
The motivation is exactly the same as for the last commit. In addition,
this anticipates us formally defining separate serialisers for the serve
protocol.

95eae0c002 Put worker protocol items inside a WorkerProto struct
See API docs on that struct for why. The pasing as as template argument
doesn't yet happen in that commit, but will instead happen in later
commit.

Also make `WorkerOp` (now `Op`) and enum struct. This led us to catch
that two operations were not handled!

469d06f9bc Split out worker protocol template definitions from declarations
This is generally a fine practice: Putting implementations in headers
makes them harder to read and slows compilation. Unfortunately it is
necessary for templates, but we can ameliorate that by putting them in a
separate header. Only files which need to instantiate those templates
will need to include the header with the implementation; the rest can
just include the declaration.

This is now documenting in the contributing guide.

Also, it just happens that these polymorphic serializers are the
protocol agnostic ones. (Worker and serve protocol have the same logic
for these container types.) This means by doing this general template
cleanup, we are also getting a head start on better indicating which
code is protocol-specific and which code is shared between protocols.

Clean up a few things related to profiles (#8526)
- Greatly expand API docs

- Clean up code in misc ways

  - Instead of a complicated single loop on generations, do different
    operations in successive subsequent steps.

  - Avoid `ref` in one place where `&` is fine

  - Just return path instead of mutating an argument in `makeName`

Add description for file system objects (#8500)
While this is not actually a notion in the implementation, it is
explicitly described in the thesis and quite important for understanding
how the store works.

d2ce2e89b1 Split OptionalPathSetting from PathSetting
Rather than doing `allowEmpty` as boolean, have separate types and use
`std::optional`. This makes it harder to forget the possibility of an
empty path.

The `build-hook` setting was categorized as a `PathSetting`, but
actually it was split into arguments. No good! Now, it is
`Setting<Strings>` which actually reflects what it means and how it is
used.

Because of the subtyping, we now also have support for
`Setting<std::optional<String>>` in general. I imagine this can be used
to clean up many more settings also.

b2247ef4f6 Don't assume the type of string::size_type
The code accidentally conflated `std::string::size_type` and `long unsigned int`.
This was fine on 64bits machines where they are apparently the same in
practice, but not on 32bits. Fix that by using `std::string::size_type`
everywhere.
