Florian Klink 6f9c54bbd1 docs(reference/nix-daemon): fix some links
[se-StorePathName] was missing in the footnotes, and links to sets were
wrong.

Also rename serialization.md to types.md to match the title.

When connecting, the handshake sequence documented below must be performed, so
client and server can agree on a protocol version to use and exchange some
parameters.
## client -> server
- 0x6e697863 :: [Int](#se-Int) (hardcoded, 'nixc' in ASCII)
## client <- server
- 0x6478696f :: [Int](#se-Int) (hardcoded, 'dxio' in ASCII)
- protocolVersion :: [Int](#se-Int)
## client -> server
- clientVersion :: [Int](#se-Int)
### If clientVersion is 1.14 or later
- sendCpu :: [Bool](#se-Bool) (hardcoded to false in client)
#### If sendCpu is true
- cpuAffinity :: [Int](#se-Int) (obsolete and ignored)
### If clientVersion is 1.11 or later
- reserveSpace :: [Bool](#se-Bool) (obsolete, ignored and set to false)
## client <- server
### If clientVersion is 1.33 or later
- nixVersion :: String
### If clientVersion is 1.35 or later
- trusted :: OptTrusted
## client <- server
- send logs
- [operation]({{< relref "operations.md" >}}) :: [Int](#se-Int)
[se-Int]: {{< relref "types.md" >}}#int
[se-Bool]: {{< relref "types.md" >}}#bool
