* Added validity checks for player names, they must be UTF-8 encoded, else game clients will crash attempting to set non-UTF-8 player names in RUI.
* CServer::RejectConnection now takes a 'v_netadr_t*', previously it was 'user_creds_s*', which worked as 'v_netadr_t' is the first member in 'user_creds_s'.
* Programmer must now manually pass a character buffer to 'v_net_adr::GetAddress(...)'.
* Use Warning() for deadlock detection debug log.
* Use const qualifiers where possible.
* Cache rtech_debug->GetBool().
* Renamed 'RPakAssetEntry' to 'RPakAssetEntry_t'.
* Renamed 'RPakDescriptor' to 'RPakDescriptor_t'.
The smart pistol's laser line overlay did not draw after the debug overlay rebuild. After some small debugging, I found out that there was a function that creates the curved trace, and creates an overlay with index 4 (originally swept_box), however, the structure is different to that of swept_box. This is laser_line. Implemented logic for drawing out laser line, which essentially just calls DrawLine (as is the case in the engine).
* Change qualifiers for some types (make const, static const, etc..).
* Renamed 'CNotifyText' to 'CTextNotify'.
* Renamed 's_LogMutex' to 'g_LogMutex' (mutex was not static).
* Use single static buffer instead of each overlay having its own (its only used in the material system thread).
* Improved readability by using ternary operators and c++ style casts.
The behavior has been changed; when a material is missing and bComplain is false, nothing gets printed to the console unless 'mat_alwaysComplain' is nonzero.
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.
