Merge files:1.1259, db_command.c:1.75, db_command.h:1.14, db_lex.c:1.23,
db_lex.h:1.15, db_main.c:1.7, db_script.c:1.1-1.2, ddb.h:1.45 from HEAD
to RELENG_7:

  Add a simple scripting facility to DDB(4), allowing the user to
  define a set of named scripts.  Each script consists of a list of DDB
  commands separated by ";"s that will be executed verbatim.  No higher
  level language constructs, such as branching, are provided for:
  scripts are executed by sequentially injecting commands into the DDB
  input buffer.

  Four new commands are present in DDB: "run" to run a specific script,
  "script" to define or print a script, "scripts" to list currently
  defined scripts, and "unscript" to delete a script, modeled on shell
  alias commands.  Scripts may also be manipulated using sysctls in the
  debug.ddb.scripting MIB space, although users will prefer to use the
  soon-to-be-added ddb(8) tool for usability reasons.

  Scripts with certain names are automatically executed on various DDB
  events, such as entering the debugger via a panic, a witness error,
  watchdog, breakpoint, sysctl, serial break, etc, allowing customized
  handling.

  Remove duplicate $FreeBSD$ that snuck in.
