Log Message:
Run external commands without flashing a console window on Windows

C's system() runs its command through cmd.exe, and when the calling
process has no console of its own -- a Windows service, sbbsctrl.exe, or
anything spawned by them -- cmd.exe allocates one, flashing a window onto
the sysop's desktop.  The web server made this obvious: every archive a
web client peeks into with ?view= runs lsar.

New in xpdev:

  xp_system() - system(), except that a console-less process spawns
  %COMSPEC% /S /C "..." with CREATE_NO_WINDOW instead.  A caller that does
  have a console still goes through system(), so console output is
  unchanged there.  Standard handles and handle inheritance are passed
  along as system() does (services.cpp hands a native service its socket
  that way).

  xp_popen() - popen(cmd, "r"), read to EOF, with the captured lines
  appended to a str_list_t.  On Windows it builds the pipe with
  CreateProcess() rather than _popen(), which requires the calling process
  to have a console and so has never worked inside a server.

system.popen() consequently works on Windows now and is no longer
documented as UNIX-only, and system.exec() no longer flashes a window.
Given the same treatment: the mail server's external mail processors, the
Services' native services, SBBSecho's external programs, and the
file-extraction command run for DIZ files.  FTP's SITE EXEC loses its
#ifdef and returns the command's output to the client on Windows too.

filecontents_lib.js drops the temp-file redirect it was using to keep
lsar off system.popen() (043587351c9) and captures the output directly.
