Align ECPG lexer more closely with the core and psql lexers.
Make a bunch of basically-cosmetic changes to reduce the diffs between
the flex rules in scan.l, psqlscan.l, and pgc.l. Reorder some code,
adjust a lot of whitespace, sync some comments, make use of flex start
condition scopes to do that.
There are a few non-cosmetic changes in the ECPG lexer:
* Bring over the decimalfail rule (and support function
process_integer_literal) so that ECPG will lex "1..10" into
the same tokens as the backend would. I'm not sure this makes any
visible difference to users, but I'm not sure it doesn't, either.
* <xdc><<EOF>> gets its own rule so as to produce a more on-point
error message.
* Remove duplicate <SQL>{xdstart} rule.
John Naylor, with a few additional changes by me
