Described in detail in internal doc TLS-SESSIONS.md Main points: - use a new `ssl_peer_key` for cache lookups by connection filters - recognize differences between TLSv1.3 and other tickets * TLSv1.3 tickets are single-use, cache can hold several of them for a peer * TLSv1.2 are reused, keep only a single one per peer - differentiate between ticket BLOB to store (that could be persisted) and object instances - use put/take/return pattern for cache access - remember TLS version, ALPN protocol, time received and lifetime of ticket - auto-expire tickets after their lifetime
… with how dynbufs work.

- GHA/windows/WinCE:
- set `-O3 -DNDEBUG` C flags manually for the CMake mingw32ce build.
CMake doesn't recognize the platform and fails to add them. To match
autotools (using `-O2`), and hit similar compiler warnings.
- enable parallel builds for cmake.
- tune parallelism for cmake using unity batches.
- tune parallelism for autotools.
Follow-up to 2a292c3 #15975
- tests: fix potentially uninitialized value in `readline()` in
`getpart.c`. Detected by gcc 4.4.0 `-O2` (Windows CE) jobs:
```
tests/server/getpart.c: In function 'getpart':
tests/server/getpart.c:298: error: 'datalen' may be used uninitialized in this function
