poc: implement PFS dumping (user titles only).

Other changes include:

* nca: add title_id and title_type fields to NcaContext; redefine title_version field in NcaContext; redefine ncaInitializeContext() function signature (now requiring NcmContentMetaKey and NcmContentInfo objects); modify ncaInitializeFsSectionContext() to make it skip extra boundary checks on FS sections with a bogus sparse storage.

* config: rename "nsp/write_section_image" flag to "nsp/write_raw_section".

* nxdt_utils: modify utilsGeneratePath() to make it also check if the first character from the filename is a slash.

* pfs: modify pfsGetEntryIndexByName() to only log an error if the entry name being looked up isn't "main.npdm".
