* Implement the ability to save directory contents as TAR.
With the ability to customize saving of specific files and also select which files are saved and which aren't.
* Implement full original TAR USTAR 255 characters path support.
* Implement file modification time and access time support for extracted/archived TAR.
* Implement full extraction of PS3UPDAT.PUP.
* Implement TAR extraction via GUI.
* Use VFS to implement missing PS3 filesystem characters escaping.
* Use VFS to error on illegal paths. (illegal paths such as malware pointing to "/../../..and so on../C:/Windows")
* Add new error types and descriptions.
* Do not crash on missing 0x100 and 0x300 PUP file entries.
* Report an error on missing PUP package inner files.
* Fix overflow in file-size against header check.
* Move all header errors to pup_object class.
* Move verbose error descriptions to pup_object class.
* Minor optimizations.
* Fix header magic test.
* Rewrite code to not use so many filesystem calls.
* Add many more error checks.
* Add missing NUL filetype.
* octalToDecimal(header.size) has been fixed to use fixed 12 characters range instead of endless string.
* Add many optimizations.
* Fix possible signed overflows with int, use the unisgned u64 type instead which allows for greater files as well.
* Log errors.
* Fix race condition in PUP installation abortion.
* Fix freezes of emulator in case the PUP installation failed due to filesystem errors.
* Use fs::create_path as opposed to fs::create_dir as it is can create upper directories in case they are missing and is better in error handling.
* Report TAR errors on failure to create directories.
* Fix pup_object constructor to not crash on invalid PUP file header. (report an error)
* Fix pup_object::validate_hashes to not crash on invalid PUP file entries. (report an error)
* Do not call Qt functions inside a named_thread because it is wrong.
* Allow emulation to work without firmware
* Fix HLE prx path detection.
* Fix manual list loading bugs.
* Fix HLE gcm
* GUI: Fix fonts search
* GUI: Hardcode sprx list
Do not depend on /dev_flash/sys/external/ contents.
Relax paranoidal mount point locking and temp dir creation mechanism.
It was incompatible with a setup where user directory is symlinked.
Instead, create temp dir as close to target as possible (see savedata).
Don't overwrite unchanged files.
Print error if failed to overwrite.
This commit affects PS3 firmware installation.
Trying to workaround a bug where some files cannot be overwritten.
