View source for TMA services

TMA (Target Manager Agent) acts as a debugging sysmodule for development kits. This system module is loaded in retail units, but remains unused.

These services are inaccessible on retail units. However, all [[Title_list#System_Applets|System Applets]] have permission to access them (see [[NPDM#Service_Access_Control]]).

TMA makes a few sets of services available. One set (the "htc" family), is aimed around managing Host/Target Connections. "htc" allows orchestrating the switch<->pc connection, "htc:tenv" allows retrieving information about the target's environment from the host, and "htcs" provides an interface for managing sockets on PC from the Switch. htcs is used primarily to host services on PC ports with actual management code running on Switch. The other service ("file_io") manages HostIO, a mechanism by which the Switch can read files present on the Host PC. When a host is connected, FS will attempt to read data via file_io when @Host:/ content paths are used, or when fsp-srv->OpenHostFileSystem() is used to open an IFileSystem to the Host PC. Nintendo's implementation only supports Windows, and FS will explicitly check for the presence of a "C:/" drive to detect this.
