* opt.ads opt.adb: Add Ada_Version_Explicit_Config along with
save/restore routines.
Properly handle Ada_Version_Explicit and Ada_Version_Config, which
were not always properly handled previously.
Since we are changing the tree format anyway, also get rid of the
junk obsolete Immediate_Errors flag.
(Tree_Read): Change the way of reading Tree_Version_String - now we
read the version string from the tree even if its length is not the
same as the length of the version string computed from Gnatvsn.
(Search_Directory_Present): New Boolean flag for the compiler.
Define Tree_Version_String as a dynamic string.
(Default_Stack_Size): new variable, used to handle switch -d.
* par-prag.adb:
For pragma Ada_2005, remove stuff about setting Ada_Version_Explicit
only for main unit.
Add pragma Ada_2005 (synonym for Ada_05)
Properly handle Ada_Version_Explicit and Ada_Version_Config, which
were not always properly handled previously.
* directio.ads, ioexcept.ads, sequenio.ads, text_io.ads: Change
explicit Ada_95 to Ada_2005.
