c585e8f9d3 poc: add file browser for NCA FS sections.
Takes advantage of the recently implemented devoptab interfaces. Supports individual file dumping and multiple file/dir dumping via highlighting. May possibly need some additional testing. The code could potentially be improved, but I'll look into it at a later time -- I just want to release this now.

Other changes include:

* devoptab: comment out log messages.

* utils: add utilsGetDirectorySize() function.

364b3f39dc romfs: use hash buckets for FS entry lookups.
* romfs: add hash bucket fields to RomFileSystemContext struct.
* romfs: remove current offset fields from RomFileSystemContext struct and all functions that relied on them.
* romfs: add romfsCalculateEntryHash().
* romfs: update romfsInitializeContext() to also load file/directory hash buckets.
* romfs: update romfsGetTotalDataSize() to make up for the removed functions.
* romfs: update romfsGetChild*EntryByName() functions to use hash bucket lookups.

Other changes include:

* devoptab: add missing exit macros to some FS operations across all interfaces.

* poc: update extractedRomFsReadThreadFunc() to make up for the removed RomFS functions.

091747d197 Custom devoptab wrappers (part 4).
Improve dirnext() calls in both PFS and HFS devoptab wrappers to make them also return bogus "." and ".." directory entries.

The "st_ino" field is now also being filled for all file entries.

Other changes include:

* libs: update libusbhsfs.
