Game bring-up: PokeMMO Prospero (PPSA98001): HTTPS sign-in and client update with #9834 and #11134

[p3n1cillin]

Status: on main the title can't reach any HTTPS server: libSceHttp has no request transport, so its requests fail with the network error. With #9834 (libSceHttp's request transport) and #11134 (default trust from the system CA list) it:

• signs in to Google Drive;
• downloads and installs its client update;
• reaches its ROM screen.

That screen needs the user's own ROMs.

Setup (the runs reported in #11134)

• Title: PokeMMO Prospero (PPSA98001, homebrew catalog), converted with the catalog runner.
• Machine: Windows 11 Pro (26300), Ryzen 5 7600X, WinLibs GCC 15.2.0, Release. Run on a separate desktop, muted.

The stop

cloud: POST send failed (0x80431063)

With #9834 alone, every HTTPS request without a verify callback fails with 0x80431063, last error 0x8095F00C (unknown CA). The libSceSsl context the title passes to sceHttpInit starts with no trust anchors.

With #9834 and #11134

• It shows Google's "Back up to Google Drive" screen with a device code: sign-in code shown (… at https://www.google.com/device).
• After "not now", its updater checks the release over HTTPS, then downloads and installs its 92 MB client: client update: download done, 92 MB in 2 s, RESULT client.update PASS.

Pull requests from this title

• feat(libSceHttp): add synchronous HTTP request transport #9834 (DoubleAAGuy): synchronous HTTP request transport in libSceHttp. fix(http): trust the system CA list for HTTPS requests #11134 is stacked on it, and feat(libSceHttp): add synchronous HTTP request transport #9834 depends on fix(http): preserve context and epoll state on allocation failure #9630.
• fix(http): trust the system CA list for HTTPS requests #11134: default HTTPS trust from the system CA list (the libSceSsl helper came with fix(http2): trust the system CA list for HTTPS requests #11145, now merged).

Open

• Nothing past the ROM screen, which needs the user's own ROMs.
