  Merged revisions 179807 via svnmerge from 
  https://origsvn.digium.com/svn/asterisk/branches/1.4
  
  I had some work to do to port these changes to trunk; the 
  check_expr stuff hasn't been updated here for quite some
  time, it appears. I added some more tests to the check_expr2
  suite. I had to play around with the makefile a bit, etc.
  
  I added STANDALONE2 #ifdefs to ast_expr2.y so as not to
  conflict structure with aelparse.

    These changes allow AEL to better check ${} constructs within $[...], that are concatenated with text.
    
    I modified and added rules in ast_expr2.fl to better handle
    the concatenations.
    
    I added some default routines to ast_expr2.y so the standalone would
    compile. It also looks like I haven't run this thru bison since 2.1, so
    it's good to get this updated.
    
    The Makefile has comments added now for check_expr2 and check_expr to
    explain what they are for, and how to run them. 
    
    The testexpr2s stuff has been removed, in favor of check_expr2.
    
    expr2.testinput has been updated to include the two expressions
    that inspired these changes (from mcnobody on #asterisk this morning)
    The regression has been run and all looks well.

# read in a file containing expressions (as if they were in $[ ]), one per line.
# It will, of course signal any syntax errors. Devs (like murf) should use this whenever
# changes are made to ast_expr2.y or ast_expr2.fl (or the corresponding .c files),
# as a regression test. Others (mere mortals?) need not bother, but they are
# more than welcome to play! The regression test itself is in expr2.testinput.
