Remove the temporary fed_libstate_t structs used in
switch_p_libstate_[save|restore], and therefore eliminate the
fed_libstate_t copies.  This required some rearranging of code to
put make the locking safe.

PTRACE_DETRACE is defined on AIX, but it is the incorrect value.
PT_DETACH is correct.

to create network tables when network string contains "us" or "US".

"us" is the POE/LoadLeveler designation for using the federation
switch.

Fix adapter_count accounting problem.

    terminate slurmd with a fatal error and don't crash slurmctld.

we can avoid dereferencing a null pointer

* Increased the size of the buffer used to store libstate from
  128KB to 1MB

* Decreased size of SNI adapter name storage from 16 to 5 bytes.
  We should never see a name with any more than 5 bytes, e.g. (sniX)

* Increased realloc block size from 4KB to 128K.  Fixed memory
  corruption problems on larger clusters

* Added lid->adapter_name caching for required for POE

* Fixed bug where next_adapter/next_window were always reset to zero
  after a call to fed_unpack_nodeinfo()

* Reformatted the output fed_print_nodeinfo()

* Increased lock section in fed_unpack_nodeinfo() to address
  race condition bug

* Fixed potential infinite loop in setup_table_entry.  Now we only
  iterate once through all windows and return error if none are
  found

* Added lock section to _copy_libstate and fed_free_libstate
