This is required as otherwise the game's exception filter will be called after ours. If we didn't handle the exception, the game's implementation, or an exception handler associated to the exception raised by address will take care of it. Unlike the game's implementation, our exception handler does not handle unknown exceptions. We only do the low level stuff reliably.
In Respawn's engine, the '-forceborder' command line parameter does the same thing as '-noborder'. '-forceborder' should remove the flags (nand) while '-noborder' should append the borderless flag. This code is an attempt to mitigate the problem. There was not enough bytes to assemble the nand operation for this code path without involving code caves or shifting.
* Add '-nosmap' command line parameter to disable signature caching.
* Invalidate the cache map after initialization.
* Add const qualifiers where possible.
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.
* Fixed bug where the system still added entries after we are initialized (file has already been written to the disk).
* Moved loading logic to CSigCache class.
* Dedicated and Host/Client now have their own cache files.
