[Pdbg] [PATCH v2 03/38] gdbserver: update gdb_parser_precompile.c, rename detach command

[Nicholas Piggin]

gdb_parser_precompile.c had not been updated since adding support for
the detach command, resulting in client error messages like this:

  Detaching from program: /home/npiggin/images/vmlinux, process 42000
  Remote doesn't know how to detach

The command handler should not be named disconnect, because that is a
different concept in gdb (disconnect leaves the target in the same
state, detach ends the debugging session).
