* Changed 'CreateDirectories' to only copy sanitized path if pointer to string is passed.
* Changed 'IsValidBase64' to only tokenize base64 value if pointer to string is passed.
This implementation was done to calculate buffer CRC on the go, as that was what the VPK file system uses for the file crc's. But it later turned out to be unnecessary, and was never reverted.
These methods where only used for and by the VPKDir_t structure.
Also renamed variable and method names to reflect new changes regarding the use of KeyValues by creating a structure with all values defined during file lookup rather than doing this during the pack process.
The CPackedStore class now heavily relies on the engine's FileSystem and KeyValues API. Since its part of the engine, it would make more sense to utilize the engine's features instead. It also allows for easier modifications.
* The logic behind the build process hasn't changed.
* Don't call copy constructor on entry blocks when building the directory file.
* Don't call copy constructor for string when we don't want to sanitize the directory file name.
The sanitizer can retrieve the directory file name from the block file name if this is passed instead. This was broken in the previous system. Sanitization can be opted out if the 3rd parameter of the 'fs_vpk_unpack' command is omitted.
* Use reference to array index.
* Only obtain array size once during loop.
* Use static buffer of 1024*1024 for decompressing.
* Removed extraneous goto.
* Fixed bug where shared data would be mapped wrong due to the last optimization.
* This increased packing performance by 40/60 seconds when rebuilding all vpk's.
* Hash chunk before compression to determine if it already exists or not (don't run compression if it does).
* Use the result of vector::insert for data sharing (insert already checks if it exists or not, and returns the iterator).
* This optimization saves around 20 seconds total when rebuilding all VPK's.
* Replaced the boolean 'fatal' parameter with a error code parameter, anything non-null will prompt a message (fatal) and terminate the process with given error code.
* Fixed bug where the global ostreamsink for spdlog did NOT get cleared in 'SQVM_PrintFunc' when cvar 'sq_showvmoutput' was < 3. Moved to global scope.
* Added error message for when detouring the process has failed, with the error code.
* Only call 'Plat_GetProcessUpTime()' once per log, (improves performance and fixes bug where the error message box would show a different time stamp than what is logged into the console or file).
* All TIER0 loggers only log to notify and console when the SDK engine has fully initialized and detoured all functions.
When fatal is set, the function will show a error dialogue, which will halt the process and close when the message is dismissed. Else we will end up in a crash.
