For consistency have the CI use the same build path as
the end-user builds.
Use where.exe from wine-10.0.
CI's version is a stub. Use one that actually works, until the CI gets
updated.
Also, fix broken RtlGenRandom by importing ADVAPI32's GetUserNameW(),
and calling GetModuleHandleW() / GetProcAddress() for SystemFunction032().
Instead of trying to use a fake import lib.
Bonus: Can now use the host system's username as the default for the
steam user name instead of "Noob".
("Noob" is still used as the fallback if this call fails, or the host
system's username is invalid.)
This creates a new "custom_master_server.txt" file that can be used to pre-seed a master server list.
This also allows for steam apps to manipulate the master server list in memory.
I.e. This implements:
Steam_Masterserver_Updater::AddMasterServer()
Steam_Masterserver_Updater::RemoveMasterServer()
Steam_Masterserver_Updater::GetNumMasterServers()
Steam_Masterserver_Updater::GetMasterServerAddress()
