Rename current_inferior as current_thread in gdbserver

Browse Source 
GDB has a function named "current_inferior" and gdbserver has a global
variable named "current_inferior", but the two are not equivalent;
indeed, gdbserver does not have any real equivalent of what GDB calls
an inferior.  What gdbserver's "current_inferior" is actually pointing
to is a structure describing the current thread.  This commit renames
current_inferior as current_thread in gdbserver to clarify this.  It
also renames the function "set_desired_inferior" to "set_desired_thread"
and renames various local variables from foo_inferior to foo_thread.
