Allocate memory using the Tcl library's memory allocation engine. Like `malloc`, but integrates with the [memory] command (if that's defined). Pairs up with [Tcl_Realloc] and [Tcl_Free].

'''`Tcl_Alloc`''' and '''`Tcl_Realloc`''' will '''panic''' if memory allocation fails.  For alternatives that return ''`NULL`'', use '''`Tcl_AttemptAlloc`''' and '''`Tcl_AttemptRealloc`'''.
