Re: [PATCH] consolidate gdbserver global data

[Stan Cox <scox@redhat.com>]

Any thoughts/comments on this patch that consolidates gdbserver external 
data as shown in this example?

(gdb) print *cs
$2 = {server_waiting_ = 0,
   extended_protocol_ = 1, response_needed_ = 1, exit_requested_ = 0, 
run_once_ = 0, multi_process_ = 1, report_fork_events_ = 1,
   report_vfork_events_ = 1, non_stop_ = 1, swbreak_feature_ = 1, 
hwbreak_feature_ = 1, disable_randomization_ = 1,
   program_argv_ = 0x682840, wrapper_argv_ = 0x0, packet_length_ = 16, 
pass_signals_ =     {0 <repeats 14 times>,
   in_buffer_ = 0x6833c0 "vCont;t:p6feb.-1ו\225\225\225\225", 
<incomplete sequence \327>, own_buffer_ = 0x689fa0 "OK",
   client_breakpoints = 0x0, ss = 0x680430, next = 0x0}

(gdb) print *cs->ss

   signal_pid_ = 28651, last_status_ = {kind = 
TARGET_WAITKIND_NO_RESUMED, value = {integer = 5, sig = GDB_SIGNAL_TRAP,
       related_pid = {pid = 5, lwp = 0, tid = 0}, execd_pathname = 0x5,
       syscall_number = 5}}, last_ptid_ = {pid = 0, lwp = 0, tid = 0},
   mem_buf_ = 0x67bc70 ,
   readchar_buf_ =  "$vCont;t:p6feb.-1#52:64bit-avx.xml:",
   readchar_bufp_ = 0x6804c4 ":64bit-avx.xml:0,fff#1bfc;",
   all_processes_ = {head = 0x682a80, tail = 0x682a80},
