Avoid race condition when handling a SIGWINCH signal

The control variable win_resized must be cleared before responding to it. Otherwise there is a small window where another SIGWINCH might occur in between the handling of an earlier SIGWINCH and the clearing of win_resized, at which point win_resized would be set (again) by the signal handler. Shortly thereafter we would clear win_resized even though we only handled the earlier SIGWINCH but not the latest one. This chain of events is all avoided if we clear win_resized first. gdb/ChangeLog: * tui/tui-win.c (tui_async_resize_screen): Clear win_resized first before resizing the window. * tui.c (tui_enable): Likewise.

/* Objdump overview.

   Objdump displays information about one or more object files, either on
   their own, or inside libraries.  It is commonly used as a disassembler,
   but it can also display information about file headers, symbol tables,
   relocations, debugging directives and more.

   The flow of execution is as follows:
 
   1. Command line arguments are checked for control switches and the
      information to be displayed is selected.
      
   2. Any remaining arguments are assumed to be object files, and they are
      processed in order by display_bfd().  If the file is an archive each
      of its elements is processed in turn.
      
   3. The file's target architecture and binary file format are determined
      by bfd_check_format().  If they are recognised, then dump_bfd() is
      called.

   4. dump_bfd() in turn calls separate functions to display the requested
      item(s) of information(s).  For example disassemble_data() is called if
      a disassembly has been requested.

   When disassembling the code loops through blocks of instructions bounded
   by symbols, calling disassemble_bytes() on each block.  The actual
   disassembling is done by the libopcodes library, via a function pointer
   supplied by the disassembler() function.  */
