feat(libSceSsl): add the connection calls

[ErenYeager1836]

What

Carried from @screamm with author attribution preserved.

Implements connection lifecycle and parameter exports in libSceSsl:

• Implements sceSslCreateConnection, sceSslConnect, sceSslRead, sceSslWrite, sceSslDeleteConnection, and sceSslSetVerifyCallback.
• Manages connection context tracking, socket peer port lookup via sceNetGetpeername, and verification callbacks following SharpProspero Http.cs bindings.
• Returns SSL_ERROR_INVALID_ID (0x8095F006) for unknown context IDs and throws on null hosts or unimplemented handshake initiation.
• Updates docs/dev/debt/libSceSsl.md.

Tested

GuestSsl.cpp: exercises connection creation, context validation, callback registration, deletion, and socket lifecycle checks.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed under Silent stubs in their library's technical debt file
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title

Thanks for carrying this. On top of current main it did not build: the old parameterless (void) stubs of sceSslCreateConnection, sceSslDeleteConnection, sceSslSetVerifyCallback, sceSslConnect, sceSslRead and sceSslWrite were still in Export.cpp (conflicting C declarations), and GuestSsl.cpp still called sceSslSetVerifyCallback() with no arguments.

I added one commit on your branch removing those stubs and the old test line. The scoped build and tests (27, including guest_ssl) pass. Merging once the Windows build is green.

sceSslConnect, sceSslRead and sceSslWrite still can't do anything here, but they now throw their own runtime_error instead of NotImplemented_nid_no_patch(__func__), so the progress report counts them as implemented. Please keep those three as NotImplemented_nid_no_patch(__func__) stubs until there is a transport. Which title calls the connection functions?

[ErenYeager1836]

Updated as requested! Kept sceSslConnect, sceSslRead, and sceSslWrite as NotImplemented_nid_no_patch(func) stubs so they remain counted as todo/unimplemented in progress reports until TLS transport is implemented, and cleaned up the unused transport exception helpers and tests.

Regarding which title calls the connection functions:

• They were originally introduced as parameterless stubs for PPSA07411 (Resident Evil 4) in commit �03afed4c (ix(exports): export the calls PPSA07411 imports), as RE4 failed to load without them.
• They are also imported by titles using fmpeg.prx (e.g., media playback/streaming).
