[RFC: 2.6 patch] net/sunrpc/: possible cleanups

[Adrian Bunk <bunk@stusta.de>]

This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
  - xdr.c: xdr_decode_string
- remove the following unneeded EXPORT_SYMBOL's:
  - auth_gss/gss_mech_switch.c: gss_mech_get
  - auth_gss/gss_mech_switch.c: gss_mech_get_by_name
  - auth_gss/gss_mech_switch.c: gss_mech_get_by_pseudoflavor
  - auth_gss/gss_mech_switch.c: gss_pseudoflavor_to_service
  - auth_gss/gss_mech_switch.c: gss_service_to_auth_domain_name
  - auth_gss/gss_mech_switch.c: gss_mech_put
  - sunrpc_syms.c: rpc_wake_up_next
  - sunrpc_syms.c: rpc_new_child
  - sunrpc_syms.c: rpc_run_child
  - sunrpc_syms.c: rpc_new_task
  - sunrpc_syms.c: rpc_release_task
  - sunrpc_syms.c: rpc_release_client
  - sunrpc_syms.c: xprt_udp_slot_table_entries
  - sunrpc_syms.c: xprt_tcp_slot_table_entries
  - sunrpc_syms.c: svc_drop
  - sunrpc_syms.c: svc_authenticate
  - sunrpc_syms.c: xdr_decode_string

Please review which of these patches do make sense and which conflict 
with pending patches.
