Implement ContentManager and related services (#438)

Browse source 
* Implement contentmanager and related services

* small changes

* read system firmware version from nand

* add pfs support, write directoryentry info for romfs files

* add file check in fsp-srv:8

* add support for open fs of internal files

* fix filename when accessing pfs

* use switch style paths for contentpath

* close nca after verifying type

* removed publishing profiles, align directory entry

* fix style

* lots of style fixes

* yasf(yet another style fix)

* yasf(yet another style fix) plus symbols

* enforce path check on every fs access

* change enum type to default

* fix typo
