Remove assorted external references from psqlscan.l in preparation for making it usable by other frontend programs. This mostly involves getting rid of direct calls to psql_error() and GetVariable() in favor of introducing a callback-functions struct to encapsulate variable fetching and error printing. In addition, pass the current encoding and standard-strings status as additional parameters to psql_scan_setup instead of looking directly at "pset" or calling additional functions. I did not bother to change some references to psql_error that are in functions that will soon migrate to a psql-specific backslash-command lexer. Other than that, this version of psqlscan.l is capable of compiling standalone. It still depends on assorted src/common functions as well as some encoding-related libpq functions, but we expect that all programs using it will be happy with those dependencies.
