8a7e1195d4 feat(exports): export the calls PPSA01317 imports
Gran Turismo 7 (PPSA01317) fails to load on unresolved imports and on
two needed libraries that AnyPS5 does not build (#4782).

- sceAppContentDownloadDataFormat empties /download0, as
  sceAppContentTemporaryDataFormat does for /temp0.
- sceNpAuthSetTimeout returns REQUEST_NOT_FOUND for an unknown request
  like the other request calls, and OK otherwise; no request reaches the
  network the timeouts would bound.
- sceNpWebApi2PushEventSetHandleTimeout throws for an unknown library
  context, like sceNpWebApi2GetMemoryPoolStats, and returns OK
  otherwise; push event handles are not tracked and nothing waits on
  one offline.
- sceSslDisableVerifyOption, sceSslGetAlpnSelected, sceSslSetAlpn,
  sceSslSetMinSslVersion, sceAudioOutDeviceIdOpen and the unnamed
  libScePsml NIDs xNZM9Y5lf-M and lcZD9tJraAw are declared without
  parameters and throw; their signatures are unknown.
- libSceUsbStorage and libSceUsbStorageDialog exist with no exports,
  like libSceXml: the title lists both as needed but imports nothing
  from them.

Each assumption is recorded in the library's technical debt file.

libSceAppContent technical debt

Unknown function info

  • sceAppContentDownloadDataGetAvailableSpaceKb (libSceAppContent) - a title whose param.json declares downloadDataSize 0 gets 0 KB and OK; the console's behaviour for a title without a download data area is unverified (it may return an error instead). KytyPS5 does not special-case it, and shadPS4 stubs 1048576 KB
  • sceAppContentGetAddcontDownloadProgress (libSceAppContent) - imported by PPSA08755, which fails to load without it; added without an implementation because its behavior is unverified. SharpProspero lists (uint32_t serviceLabel, entitlementLabel, SceAppContentAddcontDownloadProgress*), but no PS5 reference gives the progress layout or the error codes
  • sceAppContentDownloadDataFormat (libSceAppContent) - empties the /download0 directory, creating it if needed. Imported by PPSA01317. A null mount point returns PARAMETER as sceAppContentTemporaryDataFormat does, and another mount point throws as in sceAppContentDownloadDataGetAvailableSpaceKb; the console's error codes for both and its behaviour with files still open are unverified

Functional

  • Additional content (libSceAppContent) is not installed or mounted: sceAppContentAddcontMount answers NOT_FOUND for every entitlement label and sceAppContentAddcontUnmount for every mount point, as no add-content mount is ever handed out; sceAppContentGetAddcontInfo answers DRM_NO_ENTITLEMENT for every label and sceAppContentGetAddcontInfoList reports 0 entries
  • Temporary app-content storage tracks one /temp0 mount, preserves its files on unmount, and rejects new path resolutions until remount. Mount, format, space-query and unmount errors follow fpPS4; the pointer ABI is also declared by SharpProspero. Existing open host descriptors remain usable after unmount; console behaviour with open files is unverified. Host filesystem failures still throw.
